330-423 7.81e-62

FYVE, RhoGEF and PH domain containing/faciogenital dysplasia proteins 4, N-terminal Pleckstrin homology (PH) domain; In general, FGDs have a RhoGEF (DH) domain, followed by an N-terminal PH domain, a FYVE domain and a C-terminal PH domain. All FGDs are guanine nucleotide exchange factors that activates the Rho GTPase Cdc42, an important regulator of membrane trafficking. The RhoGEF domain is responsible for GEF catalytic activity, while the N-terminal PH domain is involved in intracellular targeting of the DH domain. FGD4 is one of the genes associated with Charcot-Marie-Tooth neuropathy type 4 (CMT4), a group of progressive motor and sensory axonal and demyelinating neuropathies that are distinguished from other forms of CMT by autosomal recessive inheritance. Those affected have distal muscle weakness and atrophy associated with sensory loss and, frequently, pes cavus foot deformity. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

FYVE, RhoGEF and PH domain containing/faciogenital dysplasia proteins pleckstrin homology (PH) domain, C-terminus; In general, FGDs have a RhoGEF (DH) domain, followed by an N-terminal PH domain, a FYVE domain and a C-terminal PH domain. All FGDs are guanine nucleotide exchange factors that activates the Rho GTPase Cdc42, an important regulator of membrane trafficking. The RhoGEF domain is responsible for GEF catalytic activity, while the N-terminal PH domain is involved in intracellular targeting of the DH domain. Not much is known about FGD2. FGD1 is the best characterized member of the group with mutations here leading to the X-linked disorder known as faciogenital dysplasia (FGDY). Both FGD1 and FGD3 are targeted by the ubiquitin ligase SCF(FWD1/beta-TrCP) upon phosphorylation of two serine residues in its DSGIDS motif and subsequently degraded by the proteasome. However, FGD1 and FGD3 induced significantly different morphological changes in HeLa Tet-Off cells and while FGD1 induced long finger-like protrusions, FGD3 induced broad sheet-like protrusions when the level of GTP-bound Cdc42 was significantly increased by the inducible expression of FGD3. They also reciprocally regulated cell motility in inducibly expressed in HeLa Tet-Off cells, FGD1 stimulated cell migration while FGD3 inhibited it. FGD1 and FGD3 therefore play different roles to regulate cellular functions, even though their intracellular levels are tightly controlled by the same destruction pathway through SCF(FWD1/beta-TrCP). FGD4 is one of the genes associated with Charcot-Marie-Tooth neuropathy type 4 (CMT4), a group of progressive motor and sensory axonal and demyelinating neuropathies that are distinguished from other forms of CMT by autosomal recessive inheritance.

FYVE domain found in FYVE, RhoGEF and PH domain-containing protein facio-genital dysplasia ...
461-525 4.62e-44

FYVE domain found in FYVE, RhoGEF and PH domain-containing protein facio-genital dysplasia FGD1, FGD2, FGD4; This family represents a group of Rho GTPase cell division cycle 42 (Cdc42)-specific guanine nucleotide exchange factors (GEFs), including FYVE, RhoGEF and PH domain-containing protein FGD1, FGD2 and FGD4. FGD1, also termed faciogenital dysplasia 1 protein, or Rho/Rac guanine nucleotide exchange factor FGD1 (Rho/Rac GEF), or zinc finger FYVE domain-containing protein 3, is a central regulator of extracellular matrix remodeling and belongs to the DBL family of GEFs that regulate the activation of the Rho GTPases. FGD1 is encoded by gene FGD1. Disabling mutations in the FGD1 gene cause the human X-linked developmental disorder faciogenital dysplasia (FGDY, also known as Aarskog-Scott syndrome). FGD2, also termed zinc finger FYVE domain-containing protein 4, is expressed in antigen-presenting cells, including B lymphocytes, macrophages, and dendritic cells. It localizes to early endosomes and active membrane ruffles. It plays a role in leukocyte signaling and vesicle trafficking in cells specialized to present antigen in the immune system. FGD4, also termed actin filament-binding protein frabin, or FGD1-related F-actin-binding protein, or zinc finger FYVE domain-containing protein 6, functions as an F-actin-binding (FAB) protein showing significant homology to FGD1. It induces the formation of filopodia through the activation of Cdc42 in fibroblasts. Those FGD proteins possess a similar domain organization that contains a DBL homology (DH) domain, a pleckstrin homology (PH) domain, a FYVE domain, and another PH domain in the C-terminus. However, each FGD has a unique N-terminal region that may directly or indirectly interact with F-actin. FGD1 and FGD4 have an N-terminal proline-rich domain (PRD) and an N-terminal F-actin binding (FAB) domain, respectively. This model corresponds to the FYVE domain, which has been found in many proteins involved in membrane trafficking and phosphoinositide metabolism, and has been defined by three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCR patch, and a C-terminal RVC motif, which form a compact phosphatidylinositol 3-phosphate (PtdIns3P or PI3P)-binding site. FGD1 possesses a FYVE-like domain that lack the N-terminal WxxD motif. Moreover, FGD2 is the only known RhoGEF family member shown to have a functional FYVE domain and endosomal binding activity.

461-525 4.62e-44

FYVE domain found in FYVE, RhoGEF and PH domain-containing protein facio-genital dysplasia FGD1, FGD2, FGD4; This family represents a group of Rho GTPase cell division cycle 42 (Cdc42)-specific guanine nucleotide exchange factors (GEFs), including FYVE, RhoGEF and PH domain-containing protein FGD1, FGD2 and FGD4. FGD1, also termed faciogenital dysplasia 1 protein, or Rho/Rac guanine nucleotide exchange factor FGD1 (Rho/Rac GEF), or zinc finger FYVE domain-containing protein 3, is a central regulator of extracellular matrix remodeling and belongs to the DBL family of GEFs that regulate the activation of the Rho GTPases. FGD1 is encoded by gene FGD1. Disabling mutations in the FGD1 gene cause the human X-linked developmental disorder faciogenital dysplasia (FGDY, also known as Aarskog-Scott syndrome). FGD2, also termed zinc finger FYVE domain-containing protein 4, is expressed in antigen-presenting cells, including B lymphocytes, macrophages, and dendritic cells. It localizes to early endosomes and active membrane ruffles. It plays a role in leukocyte signaling and vesicle trafficking in cells specialized to present antigen in the immune system. FGD4, also termed actin filament-binding protein frabin, or FGD1-related F-actin-binding protein, or zinc finger FYVE domain-containing protein 6, functions as an F-actin-binding (FAB) protein showing significant homology to FGD1. It induces the formation of filopodia through the activation of Cdc42 in fibroblasts. Those FGD proteins possess a similar domain organization that contains a DBL homology (DH) domain, a pleckstrin homology (PH) domain, a FYVE domain, and another PH domain in the C-terminus. However, each FGD has a unique N-terminal region that may directly or indirectly interact with F-actin. FGD1 and FGD4 have an N-terminal proline-rich domain (PRD) and an N-terminal F-actin binding (FAB) domain, respectively. This model corresponds to the FYVE domain, which has been found in many proteins involved in membrane trafficking and phosphoinositide metabolism, and has been defined by three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCR patch, and a C-terminal RVC motif, which form a compact phosphatidylinositol 3-phosphate (PtdIns3P or PI3P)-binding site. FGD1 possesses a FYVE-like domain that lack the N-terminal WxxD motif. Moreover, FGD2 is the only known RhoGEF family member shown to have a functional FYVE domain and endosomal binding activity.

FYVE zinc finger; The FYVE zinc finger is named after four proteins that it has been found in: Fab1, YOTB/ZK632.12, Vac1, and EEA1. The FYVE finger has been shown to bind two Zn++ ions. The FYVE finger has eight potential zinc coordinating cysteine positions. Many members of this family also include two histidines in a motif R+HHC+XCG, where + represents a charged residue and X any residue. We have included members which do not conserve these histidine residues but are clearly related.

Protein present in Fab1, YOTB, Vac1, and EEA1; The FYVE zinc finger is named after four proteins where it was first found: Fab1, YOTB/ZK632.12, Vac1, and EEA1. The FYVE finger has been shown to bind two Zn2+ ions. The FYVE finger has eight potential zinc coordinating cysteine positions. The FYVE finger is structurally related to the PHD finger and the RING finger. Many members of this family also include two histidines in a motif R+HHC+XCG, where + represents a charged residue and X any residue. The FYVE finger functions in the membrane recruitment of cytosolic proteins by binding to phosphatidylinositol 3-phosphate (PI3P), which is prominent on endosomes. The R+HHC+XCG motif is critical for PI3P binding.

330-423 7.81e-62

FYVE, RhoGEF and PH domain containing/faciogenital dysplasia proteins 4, N-terminal Pleckstrin homology (PH) domain; In general, FGDs have a RhoGEF (DH) domain, followed by an N-terminal PH domain, a FYVE domain and a C-terminal PH domain. All FGDs are guanine nucleotide exchange factors that activates the Rho GTPase Cdc42, an important regulator of membrane trafficking. The RhoGEF domain is responsible for GEF catalytic activity, while the N-terminal PH domain is involved in intracellular targeting of the DH domain. FGD4 is one of the genes associated with Charcot-Marie-Tooth neuropathy type 4 (CMT4), a group of progressive motor and sensory axonal and demyelinating neuropathies that are distinguished from other forms of CMT by autosomal recessive inheritance. Those affected have distal muscle weakness and atrophy associated with sensory loss and, frequently, pes cavus foot deformity. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

544-646 1.30e-53

FYVE, RhoGEF and PH domain containing/faciogenital dysplasia proteins pleckstrin homology (PH) domain, C-terminus; In general, FGDs have a RhoGEF (DH) domain, followed by an N-terminal PH domain, a FYVE domain and a C-terminal PH domain. All FGDs are guanine nucleotide exchange factors that activates the Rho GTPase Cdc42, an important regulator of membrane trafficking. The RhoGEF domain is responsible for GEF catalytic activity, while the N-terminal PH domain is involved in intracellular targeting of the DH domain. Not much is known about FGD2. FGD1 is the best characterized member of the group with mutations here leading to the X-linked disorder known as faciogenital dysplasia (FGDY). Both FGD1 and FGD3 are targeted by the ubiquitin ligase SCF(FWD1/beta-TrCP) upon phosphorylation of two serine residues in its DSGIDS motif and subsequently degraded by the proteasome. However, FGD1 and FGD3 induced significantly different morphological changes in HeLa Tet-Off cells and while FGD1 induced long finger-like protrusions, FGD3 induced broad sheet-like protrusions when the level of GTP-bound Cdc42 was significantly increased by the inducible expression of FGD3. They also reciprocally regulated cell motility in inducibly expressed in HeLa Tet-Off cells, FGD1 stimulated cell migration while FGD3 inhibited it. FGD1 and FGD3 therefore play different roles to regulate cellular functions, even though their intracellular levels are tightly controlled by the same destruction pathway through SCF(FWD1/beta-TrCP). FGD4 is one of the genes associated with Charcot-Marie-Tooth neuropathy type 4 (CMT4), a group of progressive motor and sensory axonal and demyelinating neuropathies that are distinguished from other forms of CMT by autosomal recessive inheritance. Those affected have distal muscle weakness and atrophy associated with sensory loss and, frequently, pes cavus foot deformity. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

FYVE, RhoGEF and PH domain containing/faciogenital dysplasia family proteins, N-terminal Pleckstrin homology (PH) domain; In general, FGDs have a RhoGEF (DH) domain, followed by an N-terminal PH domain, a FYVE domain and a C-terminal PH domain. All FGDs are guanine nucleotide exchange factors that activates the Rho GTPase Cdc42, an important regulator of membrane trafficking. The RhoGEF domain is responsible for GEF catalytic activity, while the N-terminal PH domain is involved in intracellular targeting of the DH domain.

461-525 4.62e-44

FYVE domain found in FYVE, RhoGEF and PH domain-containing protein facio-genital dysplasia FGD1, FGD2, FGD4; This family represents a group of Rho GTPase cell division cycle 42 (Cdc42)-specific guanine nucleotide exchange factors (GEFs), including FYVE, RhoGEF and PH domain-containing protein FGD1, FGD2 and FGD4. FGD1, also termed faciogenital dysplasia 1 protein, or Rho/Rac guanine nucleotide exchange factor FGD1 (Rho/Rac GEF), or zinc finger FYVE domain-containing protein 3, is a central regulator of extracellular matrix remodeling and belongs to the DBL family of GEFs that regulate the activation of the Rho GTPases. FGD1 is encoded by gene FGD1. Disabling mutations in the FGD1 gene cause the human X-linked developmental disorder faciogenital dysplasia (FGDY, also known as Aarskog-Scott syndrome). FGD2, also termed zinc finger FYVE domain-containing protein 4, is expressed in antigen-presenting cells, including B lymphocytes, macrophages, and dendritic cells. It localizes to early endosomes and active membrane ruffles. It plays a role in leukocyte signaling and vesicle trafficking in cells specialized to present antigen in the immune system. FGD4, also termed actin filament-binding protein frabin, or FGD1-related F-actin-binding protein, or zinc finger FYVE domain-containing protein 6, functions as an F-actin-binding (FAB) protein showing significant homology to FGD1. It induces the formation of filopodia through the activation of Cdc42 in fibroblasts. Those FGD proteins possess a similar domain organization that contains a DBL homology (DH) domain, a pleckstrin homology (PH) domain, a FYVE domain, and another PH domain in the C-terminus. However, each FGD has a unique N-terminal region that may directly or indirectly interact with F-actin. FGD1 and FGD4 have an N-terminal proline-rich domain (PRD) and an N-terminal F-actin binding (FAB) domain, respectively. This model corresponds to the FYVE domain, which has been found in many proteins involved in membrane trafficking and phosphoinositide metabolism, and has been defined by three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCR patch, and a C-terminal RVC motif, which form a compact phosphatidylinositol 3-phosphate (PtdIns3P or PI3P)-binding site. FGD1 possesses a FYVE-like domain that lack the N-terminal WxxD motif. Moreover, FGD2 is the only known RhoGEF family member shown to have a functional FYVE domain and endosomal binding activity.

330-437 2.68e-37

FYVE, RhoGEF and PH domain containing/faciogenital dysplasia protein 1, N-terminal Pleckstrin homology (PH) domain; In general, FGDs have a RhoGEF (DH) domain, followed by an N-terminal PH domain, a FYVE domain and a C-terminal PH domain. All FGDs are guanine nucleotide exchange factors that activates the Rho GTPase Cdc42, an important regulator of membrane trafficking. The RhoGEF domain is responsible for GEF catalytic activity, while the N-terminal PH domain is involved in intracellular targeting of the DH domain. Mutations in the FGD1 gene are responsible for the X-linked disorder known as faciogenital dysplasia (FGDY). Both FGD1 and FGD3 are targeted by the ubiquitin ligase SCF(FWD1/beta-TrCP) upon phosphorylation of two serine residues in its DSGIDS motif and subsequently degraded by the proteasome. However, FGD1 and FGD3 induced significantly different morphological changes in HeLa Tet-Off cells and while FGD1 induced long finger-like protrusions, FGD3 induced broad sheet-like protrusions when the level of GTP-bound Cdc42 was significantly increased by the inducible expression of FGD3. They also reciprocally regulated cell motility in inducibly expressed in HeLa Tet-Off cells, FGD1 stimulated cell migration while FGD3 inhibited it. FGD1 and FGD3 therefore play different roles to regulate cellular functions, even though their intracellular levels are tightly controlled by the same destruction pathway through SCF(FWD1/beta-TrCP). PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Protein present in Fab1, YOTB, Vac1, and EEA1; The FYVE zinc finger is named after four proteins where it was first found: Fab1, YOTB/ZK632.12, Vac1, and EEA1. The FYVE finger has been shown to bind two Zn2+ ions. The FYVE finger has eight potential zinc coordinating cysteine positions. The FYVE finger is structurally related to the PHD finger and the RING finger. Many members of this family also include two histidines in a motif R+HHC+XCG, where + represents a charged residue and X any residue. The FYVE finger functions in the membrane recruitment of cytosolic proteins by binding to phosphatidylinositol 3-phosphate (PI3P), which is prominent on endosomes. The R+HHC+XCG motif is critical for PI3P binding.

FYVE domain found in endofin and similar proteins; Endofin, also termed zinc finger FYVE domain-containing protein 16 (ZFY16), or endosome-associated FYVE domain protein, is a FYVE domain-containing protein that is localized to EEA1-containing endosomes. It is regulated by phosphoinositol lipid and engaged in endosome-mediated receptor modulation. Endofin is involved in Bone morphogenetic protein (BMP) signaling through interacting with Smad1 preferentially and enhancing Smad1 phosphorylation and nuclear localization upon BMP stimulation. It also functions as a scaffold protein that brings Smad4 to the proximity of the receptor complex in Transforming growth factor (TGF)-beta signaling. Moreover, endofin is a novel tyrosine phosphorylation target downstream of epidermal growth factor receptor (EGFR) in EGF-signaling. In addition, endofin plays a role in endosomal trafficking by recruiting cytosolic TOM1, an important molecule for membrane recruitment of clathrin, onto endosomal membranes.

FYVE domain found in FYVE, RhoGEF and PH domain-containing protein 6 (FGD6) and similar proteins; FGD6, also termed zinc finger FYVE domain-containing protein 24 is a putative Cdc42-specific guanine nucleotide exchange factor (GEF) whose biological function remains unclear. It is a homologue of FGD1 and contains a DBL homology (DH) domain and pleckstrin homology (PH) domain in the middle region, a FYVE domain, and another PH domain in the C-terminus, but lacks the N-terminal proline-rich domain (PRD) found in FGD1. Moreover, the FYVE domain of FGD6 is a canonical FYVE domain, which has been found in many proteins involved in membrane trafficking and phosphoinositide metabolism, and has been defined by three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCR patch, and a C-terminal RVC motif, which form a compact phosphatidylinositol 3-phosphate (PtdIns3P or PI3P)-binding site.

FYVE, RhoGEF and PH domain containing/faciogenital dysplasia proteins 5 and 6, N-terminal Pleckstrin Homology (PH) domain; FGD5 regulates promotes angiogenesis of vascular endothelial growth factor (VEGF) in vascular endothelial cells, including network formation, permeability, directional movement, and proliferation. The specific function of FGD6 is unknown. In general, FGDs have a RhoGEF (DH) domain, followed by a PH domain, a FYVE domain and a C-terminal PH domain. All FGDs are guanine nucleotide exchange factors that activate the Rho GTPase Cdc42, an important regulator of membrane trafficking. The RhoGEF domain is responsible for GEF catalytic activity, while the PH domain is involved in intracellular targeting of the DH domain.

FYVE domain found in lateral signaling target protein 2 homolog (Lst2) and similar proteins; Lst2, also termed zinc finger FYVE domain-containing protein 28, is a monoubiquitinylated phosphoprotein that functions as a negative regulator of epidermal growth factor receptor (EGFR) signaling. Unlike other FYVE domain-containing proteins, Lst2 displays primarily non-endosomal localization. Its endosomal localization is regulated by monoubiquitinylation. Lst2 physically binds Trim3, also known as BERP or RNF22, which is a coordinator of endosomal trafficking and interacts with Hrs and a complex that biases cargo recycling.

471-522 2.24e-17

FYVE domain like superfamily; FYVE domain is a 60-80 residue double zinc finger motif-containing module named after the four proteins, Fab1, YOTB, Vac1, and EEA1. The canonical FYVE domains are distinguished from other zinc fingers by three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCRxCG patch, and a C-terminal RVC motif, which form a compact phosphatidylinositol 3-phosphate (PtdIns3P, also termed PI3P)-binding site. They are found in many membrane trafficking regulators, including EEA1, Hrs, Vac1p, Vps27p, and FENS-1, which locate to early endosomes, specifically bind PtdIns3P, and play important roles in vesicular traffic and in signal transduction. Some proteins, such as rabphilin-3A and alpha-Rab3-interacting molecules (RIMs), are also involved in membrane trafficking and bind to members of the Rab subfamily of GTP hydrolases. However, they contain FYVE-related domains that are structurally similar to the canonical FYVE domains but lack the three signature sequences. At this point, they may not bind to phosphoinositides. In addition, this superfamily also contains the third group of proteins, caspase-associated ring proteins CARP1 and CARP2. They do not localize to membranes in the cell and are involved in the negative regulation of apoptosis, specifically targeting two initiator caspases, caspase 8 and caspase 10, which are distinguished from other FYVE-type proteins. Moreover, these proteins have an altered sequence in the basic ligand binding patch and lack the WxxD motif that is conserved only in phosphoinositide binding FYVE domains. Thus they constitute a family of unique FYVE-type domains called FYVE-like domains. The FYVE domain is structurally similar to the RING domain and the PHD finger. This superfamily also includes ADDz zinc finger domain, which is a PHD-like zinc finger motif that contains two parts, a C2-C2 and a PHD-like zinc finger.

FYVE domain found in protein containing both PH and FYVE domains 1 (phafin-1), 2 (phafin-2), and similar proteins; This family includes protein containing both PH and FYVE domains 1 (phafin-1) and 2 (phafin-2). Phafin-1 is a representative of a novel family of PH and FYVE domain-containing proteins called phafins. It is a ubiquitously expressed pro-apoptotic protein via translocating to lysosomes, facilitating apoptosis induction through a lysosomal-mitochondrial apoptotic pathway. Phafin-2 is a ubiquitously expressed endoplasmic reticulum-associated protein that facilitates tumor necrosis factor alpha (TNF-alpha)-triggered cellular apoptosis through endoplasmic reticulum (ER)-mitochondrial apoptotic pathway. It is an endosomal phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) effector, as well as an interactor of the endosomal-tethering protein EEA1. It regulates endosome fusion upstream of Rab5. Phafin-2 also functions as a novel regulator of endocytic epidermal growth factor receptor (EGFR) degradation through a role in endosomal fusion.

They are members of the Dbl family guanine nucleotide exchange factors (GEFs) which are upstream positive regulators of Rho GTPases. Little is known about FARP1 and FARP6, though FARP1 has increased expression in differentiated chondrocytes. FARP2 is thought to regulate neurite remodeling by mediating the signaling pathways from membrane proteins to Rac. It is found in brain, lung, and testis, as well as embryonic hippocampal and cortical neurons. FARP1 and FARP2 are composed of a N-terminal FERM domain, a proline-rich (PR) domain, Dbl-homology (DH), and two C-terminal PH domains. FARP6 is composed of Dbl-homology (DH), and two C-terminal PH domains separated by a FYVE domain. This hierarchy contains the first PH repeat. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized.

FYVE domain found in FYVE domain-containing protein 26 (ZFY26 or ZFYVE26); ZFY26, also termed FYVE domain-containing centrosomal protein (FYVE-CENT), or spastizin, is a phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) binding protein that localizes to the centrosome and midbody. ZFY26 and its interacting partners TTC19 and KIF13A are required for cytokinesis. It also interacts with Beclin 1, a subunit of class III phosphatidylinositol 3-kinase complex, and may have potential implications for carcinogenesis. In addition, it has been considered as the causal agent of a rare form of hereditary spastic paraplegia. ZFY26 contains a FYVE domain that is important for targeting of FYVE-CENT to the midbody.

FYVE domain found in protein containing both PH and FYVE domains 2 (phafin-2) and similar proteins; Phafin-2, also termed endoplasmic reticulum-associated apoptosis-involved protein containing PH and FYVE domains (EAPF), or pleckstrin homology domain-containing family F member 2 (PKHF2), or PH domain-containing family F member 2, or PH and FYVE domain-containing protein 2, or zinc finger FYVE domain-containing protein 18, is a ubiquitously expressed endoplasmic reticulum-associated protein that facilitates tumor necrosis factor alpha (TNF-alpha)-triggered cellular apoptosis through endoplasmic reticulum (ER)-mitochondrial apoptotic pathway. It is an endosomal phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) effector, as well as an interactor of the endosomal-tethering protein EEA1. It regulates endosome fusion upstream of Rab5. Phafin-2 also functions as a novel regulator of endocytic epidermal growth factor receptor (EGFR) degradation through a role in endosomal fusion.

317-437 1.19e-15

FYVE, RhoGEF and PH domain containing/faciogenital dysplasia protein 6, N-terminal Pleckstrin Homology (PH) domain; FGD5 regulates promotes angiogenesis of vascular endothelial growth factor (VEGF) in vascular endothelial cells, including network formation, permeability, directional movement, and proliferation. The specific function of FGD6 is unknown. In general, FGDs have a RhoGEF (DH) domain, followed by a PH domain, a FYVE domain and a C-terminal PH domain. All FGDs are guanine nucleotide exchange factors that activate the Rho GTPase Cdc42, an important regulator of membrane trafficking. The RhoGEF domain is responsible for GEF catalytic activity, while the PH domain is involved in intracellular targeting of the DH domain. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Pleckstrin homology domain; Domain commonly found in eukaryotic signalling proteins. The domain family possesses multiple functions including the abilities to bind inositol phosphates, and various proteins. PH domains have been found to possess inserted domains (such as in PLC gamma, syntrophins) and to be inserted within other domains. Mutations in Brutons tyrosine kinase (Btk) within its PH domain cause X-linked agammaglobulinaemia (XLA) in patients. Point mutations cluster into the positively charged end of the molecule around the predicted binding site for phosphatidylinositol lipids.

FYVE domain found in early endosome antigen 1 (EEA1) and similar proteins; EEA1, also termed endosome-associated protein p162, or zinc finger FYVE domain-containing protein 2, is an essential component of the endosomal fusion machinery and required for the fusion and maturation of early endosomes in endocytosis. It forms a parallel coiled-coil homodimer in cells. EEA1 serves as the p97 ATPase substrate and the p97 ATPase may regulate the size of early endosomes by governing the oligomeric state of EEA1. It can interact with the GTP-bound form of Rab22a and be involved in endosomal membrane trafficking. EEA1 also functions as an obligate scaffold for angiotensin II-induced Akt activation in early endosomes. It can be phosphorylated by p38 mitogen-activated protein kinase (MAPK) and further regulate mu opioid receptor endocytosis. EEA1 consists of an N-terminal C2H2 Zn2+ finger, four long heptad repeats, and a C-terminal region containing a calmodulin binding (IQ) motif, a Rab5 interaction site, and a FYVE domain. This model corresponds to the FYVE domain that is responsible for binding phosphatidyl inositol-3-phosphate (PtdIns3P or PI3P) on the membrane.

FYVE-like domain found in FYVE, RhoGEF and PH domain-containing protein 3 (FGD3) and similar proteins; FGD3, also termed zinc finger FYVE domain-containing protein 5, is a putative Cdc42-specific guanine nucleotide exchange factor (GEF) that undergoes the ubiquitin ligase SCFFWD1/beta-TrCP-mediated proteasomal degradation. It is a homologue of FGD1 and contains a DBL homology (DH) domain and pleckstrin homology (PH) domain in the middle region, a FYVE domain, and another PH domain in the C-terminus, but lacks the N-terminal proline-rich domain (PRD) found in FGD1. Due to this difference, FGD3 may play different roles from that of FGD1 to regulate cell morphology or motility. The FYVE domain of FGD3 resembles a FYVE-like domain that is different from the canonical FYVE domains, since it lacks one of the three conserved signature motifs (the WxxD motif) that are involved in phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) binding and exhibits altered lipid binding specificities.

FYVE domain found in WD40 repeat and FYVE domain-containing protein 3 (WDFY3) and similar proteins; WDFY3, also termed autophagy-linked FYVE protein (Alfy), is a ubiquitously expressed phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) binding protein required for selective macroautophagic degradation of aggregated proteins. It regulates the protein degradation through the direct interaction with the autophagy protein Atg5. Moreover, WDFY3 acts as a scaffold that bridges its cargo to the macroautophagic machinery via the creation of a greater complex with Atg12, Atg16L, and LC3. It also functionally associates with sequestosome-1/p62 (SQSTM1) in osteoclasts. WDFY3 shuttles between the nucleus and cytoplasm. It predominantly localizes to the nucleus and nuclear membrane under basal conditions, but is recruited to cytoplasmic ubiquitin-positive protein aggregates under stress conditions. WDFY3 contains a PH-BEACH domain assemblage, five WD40 repeats and a PtdIns3P-binding FYVE domain.

FGD5 is a homologue of FGD1 and contains a DBL homology (DH) domain, a pleckstrin homology (PH) domain, a FYVE domain, and another PH domain in the C-terminus, but lacks the N-terminal proline-rich domain (PRD) found in FGD1. The FYVE domain of FGD5 resembles a FYVE-like domain that is different from the canonical FYVE domains, since it lacks one of the three conserved signature motifs (the WxxD motif) that are involved in phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) binding and exhibits altered lipid binding specificities.

FYVE domain found in metazoan PIKfyve, fungal and plant Fab1, and similar proteins; PIKfyve, also termed FYVE finger-containing phosphoinositide kinase, or 1-phosphatidylinositol 3-phosphate 5-kinase, or phosphatidylinositol 3-phosphate 5-kinase (PIP5K3), or phosphatidylinositol 3-phosphate 5-kinase type III (PIPkin-III or type III PIP kinase), is a phosphoinositide 5-kinase that forms a complex with its regulators, the scaffolding protein Vac14 and the lipid phosphatase Fig4. The complex is responsible for synthesizing phosphatidylinositol 3,5-bisphosphate [PtdIns(3,5)P2] from phosphatidylinositol 3-phosphate (PtdIns3P or PI3P). Then phosphatidylinositol-5-phosphate (PtdIns5P) is generated directly from PtdIns(3,5)P2. PtdIns(3,5)P2 and PtdIns5P regulate endosomal trafficking and responses to extracellular stimuli. At this point, PIKfyve is vital in early embryonic development. Moreover, PIKfyve forms a complex with ArPIKfyve (associated regulator of PIKfyve) and SAC3 at the endomembranes, which plays a role in receptor tyrosine kinase (RTK) degradation. The phosphorylation of PIKfyve by AKT can facilitate Epidermal growth factor receptor (EGFR) degradation. In addition, PIKfyve may participate in the regulation of the glutamate transporters EAAT2, EAAT3 and EAAT4, and the cystic fibrosis transmembrane conductance regulator (CFTR). It is also essential for systemic glucose homeostasis and insulin-regulated glucose uptake/GLUT4 translocation in skeletal muscle. It can be activated by protein kinase B (PKB/Akt) and further up-regulates human ether-a-go-go (hERG) channels. This family also includes the yeast and plant orthologs of human PIKfyve, Fab1. PIKfyve and its orthologs share a similar architecture. They contain an N-terminal FYVE domain, a middle region related to the CCT/TCP-1/Cpn60 chaperonins that are involved in productive folding of actin and tubulin, a second middle domain that contains a number of conserved cysteine residues (CCR) unique to this family, and a C-terminal lipid kinase domain related to PtdInsP kinases.

304-425 1.72e-12

Collybistin/APC-stimulated guanine nucleotide exchange factor pleckstrin homology (PH) domain; Collybistin (also called PEM2) is homologous to the Dbl proteins ASEF (also called ARHGEF4/RhoGEF4) and SPATA13 (Spermatogenesis-associated protein 13; also called ASEF2). It activates CDC42 specifically and not any other Rho-family GTPases. Collybistin consists of an SH3 domain, followed by a RhoGEF/DH and PH domain. In Dbl proteins, the DH and PH domains catalyze the exchange of GDP for GTP in Rho GTPases, allowing them to signal to downstream effectors. It induces submembrane clustering of the receptor-associated peripheral membrane protein gephyrin, which is thought to form a scaffold underneath the postsynaptic membrane linking receptors to the cytoskeleton. It also acts as a tumor suppressor that links adenomatous polyposis coli (APC) protein, a negative regulator of the Wnt signaling pathway and promotes the phosphorylation and degradation of beta-catenin, to Cdc42. Autoinhibition of collybistin is accomplished by the binding of its SH3 domain with both the RhoGEF and PH domains to block access of Cdc42 to the GTPase-binding site. Inactivation promotes cancer progression. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

FYVE, RhoGEF and PH domain containing/faciogenital dysplasia proteins 5 and 6 pleckstrin homology (PH) domain, C-terminus; FGD5 regulates promotes angiogenesis of vascular endothelial growth factor (VEGF) in vascular endothelial cells, including network formation, permeability, directional movement, and proliferation. The specific function of FGD6 is unknown. In general, FGDs have a RhoGEF (DH) domain, followed by a PH domain, a FYVE domain and a C-terminal PH domain. All FGDs are guanine nucleotide exchange factors that activate the Rho GTPase Cdc42, an important regulator of membrane trafficking. The RhoGEF domain is responsible for GEF catalytic activity, while the PH domain is involved in intracellular targeting of the DH domain. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner.

It also acts as a novel regulator of vesicle docking and/or fusion at the endosome and functions in vesicle-mediated transport of Golgi precursor carboxypeptidase Y (CPY), protease A (PrA), protease B (PrB), but not alkaline phosphatase (ALP) from the trans-Golgi network-like compartment (TGN) to the endosome. Vac1p contains an N-terminal classical TFIIIA-like zinc finger, two putative zinc-binding FYVE fingers, and a C-terminal coiled coil region. The family corresponds to the second FYVE domain that is responsible for the ability of Pep7p to efficiently interact with Vac1p and Vps45p.

FYVE domain found in myotubularin-related protein 4 (MTMR4) and similar proteins; MTMR4, also termed FYVE domain-containing dual specificity protein phosphatase 2 (FYVE-DSP2), or zinc finger FYVE domain-containing protein 11, is an dual specificity protein phosphatase that specifically dephosphorylates phosphatidylinositol 3-phosphate (PtdIns3P or PI3P). It is localizes to early endosomes, as well as to Rab11- and Sec15-positive recycling endosomes, and regulates sorting from early endosomes. Moreover, MTMR4 is preferentially associated with and dephosphorylated the activated regulatory Smad proteins (R-Smads) in cytoplasm to keep transforming growth factor (TGF) beta signaling in homeostasis. It also functions as an essential negative modulator for the homeostasis of bone morphogenetic protein (BMP)/decapentaplegic (Dpp) signaling. In addition, MTMR4 acts as a novel interactor of the ubiquitin ligase Nedd4 (neural-precursor-cell-expressed developmentally down-regulated 4) and may play a role in the biological process of muscle breakdown. MTMR4 contains an N-terminal PH-GRAM (PH-G) domain, a MTM phosphatase domain, a coiled-coil region, and a C-terminal FYVE domain.

332-423 2.12e-10

Pleckstrin homology (PH) domain; PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

FYVE domain found in myotubularin-related protein 3 (MTMR3) and similar proteins; MTMR3, also termed Myotubularin-related phosphatase 3, or FYVE domain-containing dual specificity protein phosphatase 1 (FYVE-DSP1), or zinc finger FYVE domain-containing protein 10, is a ubiquitously expressed phosphoinositide 3-phosphatase specific for phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) and phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2) and PIKfyve, which produces PtdIns(3,5)P2 from PtdIns3P. It regulates cell migration through modulating phosphatidylinositol 5-phosphate (PtdIns5P) levels. MTMR3 contains an N-terminal PH-GRAM (PH-G) domain, a MTM phosphatase domain, a coiled-coil region, and a C-terminal FYVE domain. Unlike conventional FYVE domains, the FYVE domain of MTMR3 neither confers endosomal localization nor binds to PtdIns3P. It is also not required for the enzyme activity of MTMR3. In contrast, the PH-G domain binds phosphoinositides.

FYVE domain found in WD40 repeat and FYVE domain-containing protein WDFY1 and WDFY2, and similar proteins; This family includes WD40 repeat and FYVE domain-containing protein WDFY1 and WDFY2. WDFY1, also termed FYVE domain containing protein localized to endosomes-1 (FENS-1), or phosphoinositide-binding protein 1, or zinc finger FYVE domain-containing protein 17, is a novel single FYVE domain containing protein that binds phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) with high specificity over other phosphoinositides. WDFY1 to early endosomes requires an intact FYVE domain and is inhibited by wortmannin, a PI3-kinase inhibitor. WDFY2, also termed zinc finger FYVE domain-containing protein 22, or ProF (propeller-FYVE protein), is a phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) binding protein that is localized to a distinct subset of early endosomes close to the plasma membrane. It interacts preferentially with endogenous serine/threonine kinase Akt2, but not Akt1, and plays a specific role in modulating signaling through Akt downstream of the interaction of this kinase with the endosomal proteins APPL (adaptor protein containing PH domain, PTB domain, and leucine zipper motif). In addition to Akt, WDFY2 serves as a binding partner for protein kinase C, zeta (PRKCZ), and its substrate vesicle-associated membrane protein 2 (VAMP2), and is involved in vesicle cycling in various secretory pathways. Moreover, Silencing of WDFY2 by siRNA produces a strong inhibition of endocytosis. Both WDFY1 and WDFY2 contain a FYVE domain and multiple WD-40 repeats.

472-522 2.23e-09

FYVE domain found in hepatocyte growth factor (HGF)-regulated tyrosine kinase substrate (Hrs) and similar proteins; Hrs, also termed protein pp110, is a tyrosine phosphorylated protein that plays an important role in the signaling pathway of HGF. It is localized to early endosomes and an essential component of the endosomal sorting and trafficking machinery. Hrs interacts with hypertonia-associated protein Trak1, a novel regulator of endosome-to-lysosome trafficking. It can also forms an Hrs/actinin-4/BERP/myosin V protein complex that is required for efficient transferrin receptor (TfR) recycling but not for epidermal growth factor receptor (EGFR) degradation. Moreover, Hrs, together with STAM proteins, STAM1 and STAM2, and EPs15, forms a multivalent ubiquitin-binding complex that sorts ubiquitinated proteins into the multivesicular body pathway, and plays a regulatory role in endocytosis/exocytosis. Furthermore, Hrs functions as an interactor of the neurofibromatosis 2 tumor suppressor protein schwannomin/merlin. It is also involved in the inhibition of citron kinase-mediated HIV-1 budding. Hrs contains a single ubiquitin-interacting motif (UIM) that is crucial for its function in receptor sorting, and a FYVE domain that harbors double Zn2+ binding sites.

FYVE, RhoGEF and PH domain containing/faciogenital dysplasia protein 4 pleckstrin homology (PH) domain, C-terminus, in insect and related arthropods; In general, FGDs have a RhoGEF (DH) domain, followed by an N-terminal PH domain, a FYVE domain and a C-terminal PH domain. All FGDs are guanine nucleotide exchange factors that activates the Rho GTPase Cdc42, an important regulator of membrane trafficking. The RhoGEF domain is responsible for GEF catalytic activity, while the N-terminal PH domain is involved in intracellular targeting of the DH domain. FGD4 is one of the genes associated with Charcot-Marie-Tooth neuropathy type 4 (CMT4), a group of progressive motor and sensory axonal and demyelinating neuropathies that are distinguished from other forms of CMT by autosomal recessive inheritance. Those affected have distal muscle weakness and atrophy associated with sensory loss and, frequently, pes cavus foot deformity. This cd contains insects, crustaceans, and chelicerates. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized.

Sesquipedalian family Pleckstrin homology (PH) domain; The sesquipedalian family has 2 mammalian members: Ses1 and Ses2, which are also callled 7 kDa inositol polyphosphate phosphatase-interacting protein 1 and 2. They play a role in endocytic trafficking and are required for receptor recycling from endosomes, both to the trans-Golgi network and the plasma membrane. Members of this family form homodimers and heterodimers. Sesquipedalian interacts with inositol polyphosphate 5-phosphatase OCRL-1 (INPP5F) also known as Lowe oculocerebrorenal syndrome protein, a phosphatase enzyme that is involved in actin polymerization and is found in the trans-Golgi network and INPP5B. Sesquipedalian contains a single PH domain.

564-645 2.20e-07

Phosphoinositol 3-phosphate binding proteins 1, 2, and 3 pleckstrin homology (PH) domain; PEPP1 (also called PLEKHA4/PH domain-containing family A member 4 and RHOXF1/Rhox homeobox family member 1), and related homologs PEPP2 (also called PLEKHA5/PH domain-containing family A member 5) and PEPP3 (also called PLEKHA6/PH domain-containing family A member 6), have PH domains that interact specifically with PtdIns(3,4)P3. Other proteins that bind PtdIns(3,4)P3 specifically are: TAPP1 (tandem PH-domain-containing protein-1) and TAPP2], PtdIns3P AtPH1, and Ptd- Ins(3,5)P2 (centaurin-beta2). All of these proteins contain at least 5 of the 6 conserved amino acids that make up the putative phosphatidylinositol 3,4,5- trisphosphate-binding motif (PPBM) located at their N-terminus. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

FYVE-related domain found in uncharacterized myotubularin-related proteins mainly from eumetazoa; This family includes a group of uncharacterized myotubularin-related proteins mainly found in eumetazoa. Although their biological functions remain unclear, they share similar domain architecture that consists of an N-terminal pleckstrin homology (PH) domain, a highly conserved region related to myotubularin proteins, a C-terminal FYVE domain. The model corresponds to the FYVE domain, which resembles the FYVE-related domain as it has an altered sequence in the basic ligand binding patch.

Connector enhancer of KSR (Kinase suppressor of ras) (CNK) pleckstrin homology (PH) domain; CNK family members function as protein scaffolds, regulating the activity and the subcellular localization of RAS activated RAF. There is a single CNK protein present in Drosophila and Caenorhabditis elegans in contrast to mammals which have 3 CNK proteins (CNK1, CNK2, and CNK3). All of the CNK members contain a sterile a motif (SAM), a conserved region in CNK (CRIC) domain, and a PSD-95/DLG-1/ZO-1 (PDZ) domain, and a PH domain. A CNK2 splice variant CNK2A also has a PDZ domain-binding motif at its C terminus and Drosophila CNK (D-CNK) also has a domain known as the Raf-interacting region (RIR) that mediates binding of the Drosophila Raf kinase. This cd contains CNKs from insects, spiders, mollusks, and nematodes. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.

It suppresses formation of surplus axons for neuronal polarity. Unlike other RUFY proteins, RUFY3 can associate with the GTP-bound active form of Rab5. Moreover, the FYVE domain of RUFY3 resembles the FYVE-related domain as it lacks the WxxD motif (x for any residue).

FERM, RhoGEF and pleckstrin domain-containing protein 1 and related proteins Pleckstrin Homology (PH) domain, repeat 2; Members here include FARP1 (also called Chondrocyte-derived ezrin-like protein; PH domain-containing family C member 2), FARP2 (also called FIR/FERM domain including RhoGEF; FGD1-related Cdc42-GEF/FRG), and FARP6 (also called Zinc finger FYVE domain-containing protein 24). They are members of the Dbl family guanine nucleotide exchange factors (GEFs) which are upstream positive regulators of Rho GTPases. Little is known about FARP1 and FARP6, though FARP1 has increased expression in differentiated chondrocytes. FARP2 is thought to regulate neurite remodeling by mediating the signaling pathways from membrane proteins to Rac. It is found in brain, lung, and testis, as well as embryonic hippocampal and cortical neurons. FARP1 and FARP2 are composed of a N-terminal FERM domain, a proline-rich (PR) domain, Dbl-homology (DH), and two C-terminal PH domains. FARP6 is composed of Dbl-homology (DH), and two C-terminal PH domains separated by a FYVE domain. This hierarchy contains the second PH repeat. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized.

FYVE-related domain found in Slp homolog lacking C2 domains c (SlaC2-c) and similar proteins; SlaC2-c, also termed Rab effector MyRIP, or exophilin-8, or myosin-VIIa- and Rab-interacting protein, or synaptotagmin-like protein lacking C2 domains c, is a GTP-bound form of Rab27A-, myosin Va/VIIa-, and actin-binding protein mainly present on retinal melanosomes and secretory granules. It may play a role in insulin granule exocytosis. It is also involved in the control of isoproterenol (IPR)-induced amylase release from parotid acinar cells. SlaC2-c belongs to the Slp homolog lacking C2 domains (Slac2) family. It contains an N-terminal Slp homology domain (SHD), but lacks tandem C2 domains. The SHD consists of two conserved regions, designated SHD1 (Slp homology domain 1) and SHD2, which may function as protein interaction sites. The SHD1 and SHD2 of SlaC2-c are separated by a putative FYVE zinc finger, which resembles a FYVE-related domain that is structurally similar to the canonical FYVE domains but lacks the three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCRxCG patch, and a C-terminal RVC motif. Moreover, Slac2-c has a middle myosin-binding domain and a C-terminal actin-binding domain.

Rho GTPase activating protein 25 and related proteins Pleckstrin homology (PH) domain; RhoGAP25 (also called ArhGap25) like other RhoGaps are involved in cell polarity, cell morphology and cytoskeletal organization. They act as GTPase activators for the Rac-type GTPases by converting them to an inactive GDP-bound state and control actin remodeling by inactivating Rac downstream of Rho leading to suppress leading edge protrusion and promotes cell retraction to achieve cellular polarity and are able to suppress RAC1 and CDC42 activity in vitro. Overexpression of these proteins induces cell rounding with partial or complete disruption of actin stress fibers and formation of membrane ruffles, lamellipodia, and filopodia. This hierarchy contains RhoGAP22, RhoGAP24, and RhoGAP25. Members here contain an N-terminal PH domain followed by a RhoGAP domain and either a BAR or TATA Binding Protein (TBP) Associated Factor 4 (TAF4) domain. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized.

559-646 1.62e-06

Src kinase-associated phosphoprotein homolog and Skap 2 Pleckstrin homology (PH) domain; Adaptor protein Skap-hom, a homolog of Skap55, which interacts with actin and with ADAP (adhesion and degranulation promoting adapter protein) undergoes tyrosine phosphorylation in response to plating of bone marrow-derived macrophages on fibronectin. Skap-hom has an N-terminal coiled-coil conformation that is involved in homodimer formation, a central PH domain and a C-terminal SH3 domain that associates with ADAP. The Skap-hom PH domain regulates intracellular targeting; its interaction with the DM domain inhibits Skap-hom actin-based ruffles in macrophages and its binding to 3'-phosphoinositides reverses this autoinhibition. The Skap-hom PH domain binds PI[3,4]P2 and PI[3,4,5]P3, but not to PI[3]P, PI[5]P, or PI[4,5]P2. Skap2 is a downstream target of Heat shock transcription factor 4 (HSF4) and functions in the regulation of actin reorganization during lens differentiation. It is thought that SKAP2 anchors the complex of tyrosine kinase adaptor protein 2 (NCK20/focal adhesion to fibroblast growth factor receptors at the lamellipodium in lens epithelial cells. Skap2 has an N-terminal coiled-coil conformation which interacts with the SH2 domain of NCK2, a central PH domain and a C-terminal SH3 domain that associates with ADAP (adhesion and degranulation promoting adapter protein)/FYB (the Fyn binding protein). Skap2 PH domain binds to membrane lipids. Skap adaptor proteins couple receptors to cytoskeletal rearrangements. Src kinase-associated phosphoprotein of 55 kDa (Skap55)/Src kinase-associated phosphoprotein 1 (Skap1), Skap2, and Skap-hom have an N-terminal coiled-coil conformation, a central PH domain and a C-terminal SH3 domain. Their PH domains bind 3'-phosphoinositides as well as directly affecting targets such as in Skap55 where it directly affecting integrin regulation by ADAP and NF-kappaB activation or in Skap-hom where the dimerization and PH domains comprise a 3'-phosphoinositide-gated molecular switch that controls ruffle formation. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane.

PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

FYVE-related domain found in protrudin and similar proteins; Protrudin, also termed zinc finger FYVE domain-containing protein 27 (ZFY27 or ZFYVE27), is a FYVE domain-containing protein involved in transport of neuronal cargoes and implicated in the onset of hereditary spastic paraplegia (HSP). It is involved in neurite outgrowth through binding to spastin. Moreover, it functions as a key regulator of the Rab11-dependent membrane trafficking during neurite extension. It serves as an adaptor molecule that links its associated proteins, such as Rab11-GDP, VAP-A and -B, Surf4, and RTN3, to KIF5, a motor protein that mediates anterograde vesicular transport in neurons, and thus plays a key role in the maintenance of neuronal function. The FYVE domain of protrudin resembles a FYVE-related domain that is structurally similar to the canonical FYVE domains but lacks the three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCRxCG patch, and a C-terminal RVC motif. In addition, unlike canonical FYVE domains that is located to early endosomes and specifically binds to phosphatidylinositol 3-phosphate (PtdIns3P or PI3P), the FYVE domain of protrudin is located to plasma membrane and preferentially binds phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2), phosphatidylinositol 3,4-bisphosphate (PtdIns(3,4)P2), and phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P3). In addition to FYVE-related domain, protrudin also contains a Rab11-binding domain (RBD11), two hydrophobic domains, HP-1 and HP-2, an FFAT motif, and a coiled-coil domain.

FYVE domain found in WD40 repeat and FYVE domain-containing protein 2 (WDFY2); WDFY2, also termed zinc finger FYVE domain-containing protein 22, or ProF (propeller-FYVE protein), is a phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) binding protein that is localized to a distinct subset of early endosomes close to the plasma membrane. It interacts preferentially with endogenous serine/threonine kinase Akt2, but not Akt1, and plays a specific role in modulating signaling through Akt downstream of the interaction of this kinase with the endosomal proteins APPL (adaptor protein containing PH domain, PTB domain, and leucine zipper motif). In addition to Akt, WDFY2 serves as a binding partner for protein kinase C, zeta (PRKCZ), and its substrate vesicle-associated membrane protein 2 (VAMP2), and is involved in vesicle cycling in various secretory pathways. Moreover, Silencing of WDFY2 by siRNA produces a strong inhibition of endocytosis. WDFY2 contains WD40 motifs and a FYVE domain.

332-429 6.02e-06

ArfGAP with coiled-coil, ankyrin repeat and PH domains Pleckstrin homology (PH) domain; ACAP (also called centaurin beta) functions both as a Rab35 effector and as an Arf6-GTPase-activating protein (GAP) by which it controls actin remodeling and membrane trafficking. ACAP contain an NH2-terminal bin/amphiphysin/Rvs (BAR) domain, a phospholipid-binding domain, a PH domain, a GAP domain, and four ankyrin repeats. The AZAPs constitute a family of Arf GAPs that are characterized by an NH2-terminal pleckstrin homology (PH) domain and a central Arf GAP domain followed by two or more ankyrin repeats. On the basis of sequence and domain organization, the AZAP family is further subdivided into four subfamilies: 1) the ACAPs contain an NH2-terminal bin/amphiphysin/Rvs (BAR) domain (a phospholipid-binding domain that is thought to sense membrane curvature), a single PH domain followed by the GAP domain, and four ankyrin repeats; 2) the ASAPs also contain an NH2-terminal BAR domain, the tandem PH domain/GAP domain, three ankyrin repeats, two proline-rich regions, and a COOH-terminal Src homology 3 domain; 3) the AGAPs contain an NH2-terminal GTPase-like domain (GLD), a split PH domain, and the GAP domain followed by four ankyrin repeats; and 4) the ARAPs contain both an Arf GAP domain and a Rho GAP domain, as well as an NH2-terminal sterile-a motif (SAM), a proline-rich region, a GTPase-binding domain, and five PH domains. PMID 18003747 and 19055940 Centaurin can bind to phosphatidlyinositol (3,4,5)P3. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

331-427 8.75e-06

Cloned out of library/PAK-interactive exchange factor pleckstrin homology (PH) domain; There are two forms of Pix proteins: alpha Pix (also called Rho guanine nucleotide exchange factor (GEF) 6/90Cool-2) and beta Pix (GEF7/p85Cool-1). betaPix contains an N-terminal SH3 domain, a RhoGEF/DH domain, a PH domain, a GIT1 binding domain (GBD), and a C-terminal coiled-coil (CC) domain. alphaPix differs in that it contains a calponin homology (CH) domain, which interacts with beta-parvin, N-terminal to the SH3 domain. alphaPix is an exchange factor for Rac1 and Cdc42 and mediates Pak activation on cell adhesion to fibronectin. Mutations in alphaPix can cause X-linked mental retardation. alphaPix also interacts with Huntington's disease protein (htt), and enhances the aggregation of mutant htt (muthtt) by facilitating SDS-soluble muthtt-muthtt interactions. The DH-PH domain of a Pix was required for its binding to htt. In the majority of Rho GEF proteins, the DH-PH domain is responsible for the exchange activity. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.

A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Pleckstrin homology (PH) domain containing, family H (with MyTH4 domain) members 1 and 2 (PLEKHH1) PH domain, repeat 1; PLEKHH1 and PLEKHH2 (also called PLEKHH1L) are thought to function in phospholipid binding and signal transduction. There are 3 Human PLEKHH genes: PLEKHH1, PLEKHH2, and PLEKHH3. There are many isoforms, the longest of which contain a FERM domain, a MyTH4 domain, two PH domains, a peroximal domain, a vacuolar domain, and a coiled coil stretch. The FERM domain has a cloverleaf tripart structure (FERM_N, FERM_M, FERM_C/N, alpha-, and C-lobe/A-lobe, B-lobe, C-lobe/F1, F2, F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.

472-522 1.56e-05

FYVE domain found in Saccharomyces cerevisiae vacuolar protein sorting-associated protein 27 (scVps27p) and FYVE-related domain 1 found in yeast protein VAC1 (Vac1p) and similar proteins; The family includes Saccharomyces cerevisiae vacuolar protein sorting-associated protein 27 (scVps27p) and protein VAC1 (Vac1p). scVps27p, also termed Golgi retention defective protein 11, is the putative yeast counterpart of the mammalian protein Hrs and is involved in endosome maturation. It is a mono-ubiquitin-binding protein that interacts with ubiquitinated cargoes, such as Hse1p, and is required for protein sorting into the multivesicular body. Vps27p forms a complex with Hse1p. The complex binds ubiquitin and mediates endosomal protein sorting. At the endosome, Vps27p and a trimeric protein complex, ESCRT-1, bind ubiquitin and are important for multivesicular body (MVB) sorting. Vps27p contains an N-terminal VHS (Vps27/Hrs/STAM) domain, a FYVE domain that binds PtdIns3P, followed by two ubiquitin-interacting motifs (UIMs), and a C-terminal clathrin-binding motif. Vac1p, also termed vacuolar segregation protein Pep7p, or carboxypeptidase Y-deficient protein 7, or vacuolar protein sorting-associated protein 19 (Vps19p), or vacuolar protein-targeting protein 19, is a phosphatidylinositol 3-phosphate (PtdIns3P or PI3P)-binding protein that interacts with a Rab GTPase, GTP-bound form of Vps21p, and a Sec1p homologue, Vps45p, to facilitate Vps45p-dependent vesicle-mediated vacuolar protein sorting. It also acts as a novel regulator of vesicle docking and/or fusion at the endosome and functions in vesicle-mediated transport of Golgi precursor carboxypeptidase Y (CPY), protease A (PrA), protease B (PrB), but not alkaline phosphatase (ALP) from the trans-Golgi network-like compartment (TGN) to the endosome. Vac1p contains an N-terminal classical TFIIIA-like zinc finger, two putative zinc-binding FYVE fingers, and a C-terminal coiled coil region. The FYVE domain in both Vps27p and Vac1p harbors a zinc-binding site composed of seven Cysteines and one Histidine, which is different from that of other FYVE domain containing proteins.

327-423 3.57e-05

Son of Sevenless (SOS) Pleckstrin homology (PH) domain; SOS is a Ras guanine nucleotide exchange factor. SOS is thought to transmit signals from activated receptor tyrosine kinases to the Ras signaling pathway. SOS contains a histone domain, Dbl-homology (DH), a PH domain, Rem domain, Cdc25 domain, and a Grb2 binding domain. The SOS PH domain binds to phosphatidylinositol-4,5-bisphosphate (PIP2) and phosphatidic acid (PA). SOS is dependent on Ras binding to the allosteric site via its histone domain for both a lower level of activity (Ras GDP) and maximal activity (Ras GTP). The DH domain blocks the allosteric Ras binding site in SOS. The PH domain is closely associated with the DH domain and the action of the DH-PH unit gates a reciprocal interaction between Ras and SOS. The C-terminal proline-rich domain of SOS binds to the adapter protein Grb2 which localizes the Sos protein to the plasma membrane and diminishes the negative effect of the C-terminal domain on the guanine nucleotide exchange activity of the CDC25-homology domain of SOS. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

323-423 5.13e-05

Ephexin Pleckstrin homology (PH) domain; Ephexin-1 (also called NGEF/ neuronal guanine nucleotide exchange factor) plays a role in the homeostatic modulation of presynaptic neurotransmitter release. Specific functions are still unknown for Ephexin-2 (also called RhoGEF19) and Ephexin-3 (also called Rho guanine nucleotide exchange factor 5/RhoGEF5, Transforming immortalized mammary oncogene/p60 TIM, and NGEF/neuronalGEF). Ephexin-4 (also called RhoGEF16) acts downstream of EphA2 to promote ligand-independent breast cancer cell migration and invasion toward epidermal growth factor through activation of RhoG. This in turn results in the activation of RhoG which recruits ELMO2 and Dock4 to form a complex with EphA2 at the tips of cortactin-rich protrusions in migrating breast cancer cells. Ephexin-5 is the specific GEF for RhoA activation and the regulation of vascular smooth muscle contractility. It interacts with EPHA4 PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. The members of the Ephexin family contains a RhoGEF (DH) followed by a PH domain and an SH3 domain. The ephexin PH domain is believed to act with the DH domain in mediating protein-protein interactions. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

332-424 5.49e-05

Dual Adaptor for Phosphotyrosine and 3-Phosphoinositides Pleckstrin homology (PH) domain; DAPP1 (also known as PHISH/3' phosphoinositide-interacting SH2 domain-containing protein or Bam32) plays a role in B-cell activation and has potential roles in T-cell and mast cell function. DAPP1 promotes B cell receptor (BCR) induced activation of Rho GTPases Rac1 and Cdc42, which feed into mitogen-activated protein kinases (MAPK) activation pathways and affect cytoskeletal rearrangement. DAPP1can also regulate BCR-induced activation of extracellular signal-regulated kinase (ERK), and c-jun NH2-terminal kinase (JNK). DAPP1 contains an N-terminal SH2 domain and a C-terminal pleckstrin homology (PH) domain with a single tyrosine phosphorylation site located centrally. DAPP1 binds strongly to both PtdIns(3,4,5)P3 and PtdIns(3,4)P2. The PH domain is essential for plasma membrane recruitment of PI3K upon cell activation. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Src kinase-associated phosphoprotein family Pleckstrin homology (PH) domain; Skap adaptor proteins couple receptors to cytoskeletal rearrangements. Src kinase-associated phosphoprotein of 55 kDa (Skap55)/Src kinase-associated phosphoprotein 1 (Skap1), Skap2, and Skap-homology (Skap-hom) have an N-terminal coiled-coil conformation, a central PH domain and a C-terminal SH3 domain. Their PH domains bind 3'-phosphoinositides as well as directly affecting targets such as in Skap55 where it directly affecting integrin regulation by ADAP and NF-kappaB activation or in Skap-hom where the dimerization and PH domains comprise a 3'-phosphoinositide-gated molecular switch that controls ruffle formation. PH domains are only found in eukaryotes. They share little sequence conservation, but all have a common fold, which is electrostatically polarized.

554-648 7.56e-05

Actin filament associated protein family Pleckstrin homology (PH) domain, repeat 2; There are 3 members of the AFAP family of adaptor proteins: AFAP1, AFAP1L1, and AFAP1L2/XB130. AFAP1 is a cSrc binding partner and actin cross-linking protein. AFAP1L1 is thought to play a similar role to AFAP1 in terms of being an actin cross-linking protein, but it preferentially binds to cortactin and not cSrc, thereby playing a role in invadosome formation. AFAP1L2 is a cSrc binding protein, but does not bind to actin filaments. AFAP1L2 acts as an intermediary between the RET/PTC kinase and PI-3kinase pathway in the thyroid. The AFAPs share a similar structure of a SH3 binding motif, 3 SH2 binding motifs, 2 PH domains, a coiled-coil region corresponding to the AFAP1 leucine zipper, and an actin binding domain. This cd is the second PH domain of AFAP. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.

FYVE-related domain 1 found in yeast protein VAC1 (Vac1p) and similar proteins; Vac1p, also termed vacuolar segregation protein Pep7p, or carboxypeptidase Y-deficient protein 7, or vacuolar protein sorting-associated protein 19 (Vps19p), or vacuolar protein-targeting protein 19, is a phosphatidylinositol 3-phosphate (PtdIns3P or PI3P)-binding protein that interacts with a Rab GTPase, GTP-bound form of Vps21p, and a Sec1p homologue, Vps45p, to facilitate Vps45p-dependent vesicle-mediated vacuolar protein sorting. It also acts as a novel regulator of vesicle docking and/or fusion at the endosome and functions in vesicle-mediated transport of Golgi precursor carboxypeptidase Y (CPY), protease A (PrA), protease B (PrB), but not alkaline phosphatase (ALP) from the trans-Golgi network-like compartment (TGN) to the endosome. Vac1p contains an N-terminal classical TFIIIA-like zinc finger, two putative zinc-binding FYVE fingers, and a C-terminal coiled coil region. The family corresponds to the first FYVE domain, which resembles the FYVE-related domain as it has an altered sequence in the basic ligand binding patch.

There are 3 Human PLEKHH genes: PLEKHH1, PLEKHH2, and PLEKHH3. There are many isoforms, the longest of which contain a FERM domain, a MyTH4 domain, two PH domains, a peroximal domain, a vacuolar domain, and a coiled coil stretch. The FERM domain has a cloverleaf tripart structure (FERM_N, FERM_M, FERM_C/N, alpha-, and C-lobe/A-lobe, B-lobe, C-lobe/F1, F2, F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.

Autophagy-related protein 26/Sterol 3-beta-glucosyltransferase Pleckstrin homology (PH) domain, repeat 1; ATG26 (also called UGT51/UDP-glycosyltransferase 51), a member of the glycosyltransferase 28 family, resulting in the biosynthesis of sterol glucoside. ATG26 in decane metabolism and autophagy. There are 32 known autophagy-related (ATG) proteins, 17 are components of the core autophagic machinery essential for all autophagy-related pathways and 15 are the additional components required only for certain pathways or species. The core autophagic machinery includes 1) the ATG9 cycling system (ATG1, ATG2, ATG9, ATG13, ATG18, and ATG27), 2) the phosphatidylinositol 3-kinase complex (ATG6/VPS30, ATG14, VPS15, and ATG34), and 3) the ubiquitin-like protein system (ATG3, ATG4, ATG5, ATG7, ATG8, ATG10, ATG12, and ATG16). Less is known about how the core machinery is adapted or modulated with additional components to accommodate the nonselective sequestration of bulk cytosol (autophagosome formation) or selective sequestration of specific cargos (Cvt vesicle, pexophagosome, or bacteria-containing autophagosome formation). The pexophagosome-specific additions include the ATG30-ATG11-ATG17 receptor-adaptors complex, the coiled-coil protein ATG25, and the sterol glucosyltransferase ATG26. ATG26 is necessary for the degradation of medium peroxisomes. It contains 2 GRAM domains and a single PH domain. PH domains are only found in eukaryotes. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. PH domains also have diverse functions. They are often involved in targeting proteins to the plasma membrane, but few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains.

378-435 2.62e-04

Human Oxysterol binding protein related protein 9 Pleckstrin homology (PH) domain; Human ORP9 is proposed to function in regulation of Akt phosphorylation. ORP9 has 2 forms, a long (ORP9L) and a short (ORP9S). ORP9L contains an N-terminal PH domain, a FFAT motif (two phenylalanines in an acidic tract), and a C-terminal OSBP-related domain. ORP1S is truncated and contains a FFAT motif and an OSBP-related domain. Oxysterol binding proteins are a multigene family that is conserved in yeast, flies, worms, mammals and plants. In general OSBPs and ORPs have been found to be involved in the transport and metabolism of cholesterol and related lipids in eukaryotes. They all contain a C-terminal oxysterol binding domain, and most contain an N-terminal PH domain. OSBP PH domains bind to membrane phosphoinositides and thus likely play an important role in intracellular targeting. They are members of the oxysterol binding protein (OSBP) family which includes OSBP, OSBP-related proteins (ORP), Goodpasture antigen binding protein (GPBP), and Four phosphate adaptor protein 1 (FAPP1). They have a wide range of purported functions including sterol transport, cell cycle control, pollen development and vessicle transport from Golgi recognize both PI lipids and ARF proteins. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

377-427 5.08e-04

Bruton's tyrosine kinase pleckstrin homology (PH) domain; Btk is a member of the Tec family of cytoplasmic protein tyrosine kinases that includes BMX, IL2-inducible T-cell kinase (Itk) and Tec. Btk plays a role in the maturation of B cells. Tec proteins general have an N-terminal PH domain, followed by a Tek homology (TH) domain, a SH3 domain, a SH2 domain and a kinase domain. The Btk PH domain binds phosphatidylinositol 3,4,5-trisphosphate and responds to signalling via phosphatidylinositol 3-kinase. The PH domain is also involved in membrane anchoring which is confirmed by the discovery of a mutation of a critical arginine residue in the BTK PH domain. This results in severe human immunodeficiency known as X-linked agammaglobulinemia (XLA) in humans and a related disorder is mice.PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

331-423 9.21e-04

Type 2 Diacylglycerol kinase Pleckstrin homology (PH) domain; DGK (also called DAGK) catalyzes the conversion of diacylglycerol (DAG) to phosphatidic acid (PA) utilizing ATP as a source of the phosphate. In non-stimulated cells, DGK activity is low and DAG is used for glycerophospholipid biosynthesis. Upon receptor activation of the phosphoinositide pathway, DGK activity increases which drives the conversion of DAG to PA. DGK acts as a switch by terminating the signalling of one lipid while simultaneously activating signalling by another. There are 9 mammalian DGK isoforms all with conserved catalytic domains and two cysteine rich domains. These are further classified into 5 groups according to the presence of additional functional domains and substrate specificity: Type 1 - DGK-alpha, DGK-beta, DGK-gamma - contain EF-hand motifs and a recoverin homology domain; Type 2 - DGK-delta, DGK-eta, and DGK-kappa- contain a pleckstrin homology domain, two cysteine-rich zinc finger-like structures, and a separated catalytic region; Type 3 - DGK-epsilon - has specificity for arachidonate-containing DAG; Type 4 - DGK-zeta, DGK-iota- contain a MARCKS homology domain, ankyrin repeats, a C-terminal nuclear localization signal, and a PDZ-binding motif; Type 5 - DGK-theta - contains a third cysteine-rich domain, a pleckstrin homology domain and a proline rich region. The type 2 DGKs are present as part of this Metazoan DGK hierarchy. They have a N-terminal PH domain, two cysteine rich domains, followed by bipartite catalytic domains, and a C-terminal SAM domain. Their catalytic domains and perhaps other DGK catalytic domains may function as two independent units in a coordinated fashion. They may also require other motifs for maximal activity because several DGK catalytic domains have very little DAG kinase activity when expressed as isolated subunits. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

328-436 1.00e-03

Switch-associated protein-70 Pleckstrin homology (PH) domain; SWAP-70 (also called Differentially expressed in FDCP 6/DEF-6 or IRF4-binding protein) functions in cellular signal transduction pathways (in conjunction with Rac), regulates cell motility through actin rearrangement, and contributes to the transformation and invasion activity of mouse embryo fibroblasts. Metazoan SWAP-70 is found in B lymphocytes, mast cells, and in a variety of organs. Metazoan SWAP-70 contains an N-terminal EF-hand motif, a centrally located PH domain, and a C-terminal coiled-coil domain. The PH domain of Metazoan SWAP-70 contains a phosphoinositide-binding site and a nuclear localization signal (NLS), which localize SWAP-70 to the plasma membrane and nucleus, respectively. The NLS is a sequence of four Lys residues located at the N-terminus of the C-terminal a-helix; this is a unique characteristic of the Metazoan SWAP-70 PH domain. The SWAP-70 PH domain binds PtdIns(3,4,5)P3 and PtdIns(4,5)P2 embedded in lipid bilayer vesicles. There are additional plant SWAP70 proteins, but these are not included in this hierarchy. Rice SWAP70 (OsSWAP70) exhibits GEF activity toward the its Rho GTPase, OsRac1, and regulates chitin-induced production of reactive oxygen species and defense gene expression in rice. Arabidopsis SWAP70 (AtSWAP70) plays a role in both PAMP- and effector-triggered immunity. Plant SWAP70 contains both DH and PH domains, but their arrangement is the reverse of that in typical DH-PH-type Rho GEFs, wherein the DH domain is flanked by a C-terminal PH domain. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.

580-648 1.45e-03

SifA and kinesin-interacting protein Pleckstrin homology (PH) domain; SKIP (also called PLEKHM2/Pleckstrin homology domain-containing family M member 2) is a soluble cytosolic protein that contains a RUN domain and a PH domain separated by a unstructured linker region. SKIP is a target of the Salmonella effector protein SifA and the SifA-SKIP complex regulates kinesin-1 on the bacterial vacuole. The PH domain of SKIP binds to the N-terminal region of SifA while the N-terminus of SKIP is proposed to bind the TPR domain of the kinesin light chain. The opposite side of the SKIP PH domain is proposed to bind phosphoinositides. TSifA, SKIP, SseJ, and RhoA family GTPases are also thought to promote host membrane tubulation. Recently, it was shown that the lysosomal GTPase Arl8 binds to the kinesin-1 linker SKIP and that both are required for the normal intracellular distribution of lysosomes. Interestingly, two kinesin light chain binding motifs (WD) in SKIP have now been identified to match a consensus sequence for a kinesin light chain binding site found in several proteins including calsyntenin-1/alcadein, caytaxin, and vaccinia virus A36. SKIP has also been shown to interact with Rab1A. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.

PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Phospholipase D pleckstrin homology (PH) domain; PLD hydrolyzes phosphatidylcholine to phosphatidic acid (PtdOH), which can bind target proteins. PLD contains a PH domain, a PX domain and four conserved PLD signature domains. The PLD PH domain is specific for bisphosphorylated inositides. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner.

Connector enhancer of KSR (Kinase suppressor of ras) (CNK) pleckstrin homology (PH) domain; CNK family members function as protein scaffolds, regulating the activity and the subcellular localization of RAS activated RAF. There is a single CNK protein present in Drosophila and Caenorhabditis elegans in contrast to mammals which have 3 CNK proteins (CNK1, CNK2, and CNK3). All of the CNK members contain a sterile a motif (SAM), a conserved region in CNK (CRIC) domain, and a PSD-95/DLG-1/ZO-1 (PDZ) domain, and, with the exception of CNK3, a PH domain. A CNK2 splice variant CNK2A also has a PDZ domain-binding motif at its C terminus and Drosophila CNK (D-CNK) also has a domain known as the Raf-interacting region (RIR) that mediates binding of the Drosophila Raf kinase. This cd contains CNKs from mammals, chickens, amphibians, fish, and crustacea. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.

472-518 2.04e-03

FYVE-related domain found in synaptotagmin-like protein 4 (Slp4) and similar proteins; Slp4, also termed exophilin-2, or granuphilin, has been characterized as a regulator of the release of insulin granules from pancreatic beta-cells and dense core granules from PC12 neuronal cells by binding to Rab27A , and amylase granules from parotid gland acinar cells through interaction with syntaxin-2/3 in a Munc18-2-dependent manner on the apical plasma membrane. It can binds to syntaxin 2 in parotid acinar cells. It is also involved in granule transport by recruitment of the motor protein myosin Va. Moreover, it requires Rab8 to increase granule release in platelets. Slp4 contains an N-terminal Slp homology domain (SHD) and C-terminal tandem C2 domains. The Slp homology domain (SHD) consists of two conserved regions, designated SHD1 (Slp homology domain 1) and SHD2, which may function as protein interaction sites. The SHD1 and SHD2 of Slp4 are separated by a putative FYVE zinc finger, which resembles a FYVE-related domain that is structurally similar to the canonical FYVE domains but lacks the three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCRxCG patch, and a C-terminal RVC motif.

FYVE-related domain found in Slp homolog lacking C2 domains a (SlaC2-a) and similar proteins; SlaC2-a, also termed melanophilin, or exophilin-3, is a GTP-bound form of Rab27A-, myosin Va-, and actin-binding protein present on melanosomes. It is involved in the control of transferring of melanosomes from microtubules to actin filaments. It also functions as a melanocyte type myosin Va (McM5) binding partner and directly activates the actin-activated ATPase activity of McM5 through forming a tripartite protein complex with Rab27A and an actin-based motor myosin Va. SlaC2-a belongs to the Slp homolog lacking C2 domains (Slac2) family. It contains an N-terminal Slp homology domain (SHD), but lacks tandem C2 domains. The SHD consists of two conserved regions, designated SHD1 (Slp homology domain 1) and SHD2, which may function as protein interaction sites. The SHD1 and SHD2 of SlaC2-a are separated by a putative FYVE zinc finger, which resembles a FYVE-related domain that is structurally similar to the canonical FYVE domains but lacks the three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCRxCG patch, and a C-terminal RVC motif. Moreover, Slac2-a has a middle myosin-binding domain and a C-terminal actin-binding domain.

581-645 3.42e-03

Boi family Pleckstrin homology domain; Yeast Boi proteins Boi1 and Boi2 are functionally redundant and important for cell growth with Boi mutants displaying defects in bud formation and in the maintenance of cell polarity.They appear to be linked to Rho-type GTPase, Cdc42 and Rho3. Boi1 and Boi2 display two-hybrid interactions with the GTP-bound ("active") form of Cdc42, while Rho3 can suppress of the lethality caused by deletion of Boi1 and Boi2. These findings suggest that Boi1 and Boi2 are targets of Cdc42 that promote cell growth in a manner that is regulated by Rho3. Boi proteins contain a N-terminal SH3 domain, followed by a SAM (sterile alpha motif) domain, a proline-rich region, which mediates binding to the second SH3 domain of Bem1, and C-terminal PH domain. The PH domain is essential for its function in cell growth and is important for localization to the bud, while the SH3 domain is needed for localization to the neck. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

IQ motif and SEC7 domain-containing protein family Pleckstrin homology domain; The IQSEC (also called BRAG/Brefeldin A-resistant Arf-gunanine nucleotide exchange factor) family are a subset of Arf GEFs that have been shown to activate Arf6, which acts in the endocytic pathway to control the trafficking of a subset of cargo proteins including integrins and have key roles in the function and organization of distinct excitatory and inhibitory synapses in the retina. The family consists of 3 members: IQSEC1 (also called BRAG2/GEP100), IQSEC2 (also called BRAG1), and IQSEC3 (also called SynArfGEF, BRAG3, or KIAA1110). IQSEC1 interacts with clathrin and modulates cell adhesion by regulating integrin surface expression and in addition to Arf6, it also activates the class II Arfs, Arf4 and Arf5. Mutations in IQSEC2 cause non-syndromic X-linked intellectual disability as well as reduced activation of Arf substrates (Arf1, Arf6). IQSEC3 regulates Arf6 at inhibitory synapses and associates with the dystrophin-associated glycoprotein complex and S-SCAM. These members contains a IQ domain that may bind calmodulin, a PH domain that is thought to mediate membrane localization by binding of phosphoinositides, and a SEC7 domain that can promote GEF activity on ARF. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Triple functional domain pleckstrin homology pleckstrin homology (PH) domain, repeat 1; RhoGEFs, Kalirin and Trio, the mammalian homologs of Drosophila Trio and Caenorhabditis elegans UNC-73 regulate a novel step in secretory granule maturation. Their signaling modulates the extent to which regulated cargo enter and remain in the regulated secretory pathway. This allows for fine tuning of peptides released by a single secretory cell type with impaired signaling leading to pathological states. Trio plays an essential role in regulating the actin cytoskeleton during axonal guidance and branching. Kalirin and Trio are encoded by separate genes in mammals and by a single one in invertebrates. Kalirin and Trio share the same complex multidomain structure and display several splice variants. The longest Kalirin and Trio proteins have a Sec14 domain, a stretch of spectrin repeats, a RhoGEF(DH)/PH cassette (also called GEF1), an SH3 domain, a second RhoGEF(DH)/PH cassette (also called GEF2), a second SH3 domain, Ig/FNIII domains, and a kinase domain. The first RhoGEF(DH)/PH cassette catalyzes exchange on Rac1 and RhoG while the second RhoGEF(DH)/PH cassette is specific for RhoA. Kalirin and Trio are closely related to p63RhoGEF and have PH domains of similar function. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.

A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains.

544-642 5.77e-03

Actin filament associated protein family Pleckstrin homology (PH) domain, repeat 1; There are 3 members of the AFAP family of adaptor proteins: AFAP1, AFAP1L1, and AFAP1L2/XB130. AFAP1 is a cSrc binding partner and actin cross-linking protein. AFAP1L1 is thought to play a similar role to AFAP1 in terms of being an actin cross-linking protein, but it preferentially binds to cortactin and not cSrc, thereby playing a role in invadosome formation. AFAP1L2 is a cSrc binding protein, but does not bind to actin filaments. AFAP1L2 acts as an intermediary between the RET/PTC kinase and PI-3kinase pathway in the thyroid. The AFAPs share a similar structure of a SH3 binding motif, 3 SH2 binding motifs, 2 PH domains, a coiled-coil region corresponding to the AFAP1 leucine zipper, and an actin binding domain. The amino terminal PH1 domain of AFAP1 has been known to function in intra-molecular regulation of AFAP1. In addition, the PH1 domain is a binding partner for PKCa and phospholipids. This cd is the first PH domain of AFAP. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.

397-429 5.91e-03

Alsin Pleckstrin homology (PH) domain; The ALS2 gene encodes alsin, a GEF, that has dual specificity for Rac1 and Rab5 GTPases. Alsin mutations in the form of truncated proteins are responsible for motor function disorders including juvenile-onset amyotrophic lateral sclerosis, familial juvenile primary lateral sclerosis, and infantile-onset ascending hereditary spastic paralysis. The alsin protein is widely expressed in the developing CNS including neurons of the cerebral cortex, brain stem, spinal cord, and cerebellum. Alsin contains a regulator of chromosome condensation 1 (RCC1) domain, a Rho guanine nucleotide exchanging factor (RhoGEF) domain, a PH domain, a Membrane Occupation and Recognition Nexus (MORN), a vacuolar protein sorting 9 (Vps9) domain, and a Dbl homology (DH) domain. Alsin interacts with Rab5 through its Vps9 domain and through this interaction modulates early endosome fusion and trafficking. The GEF activity of alsin towards Rab5 is regulated by Rac1 function. The GEF activity of alsin for Rac1 occurs via its DH domain and this interaction plays a role in promoting spinal motor neuron survival via multiple Rac-dependent signaling pathways. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.
