 806-1045 6.11e-75

Guanine nucleotide exchange factor for Ras-like small GTPases. Small GTP-binding proteins of the Ras superfamily function as molecular switches in fundamental events such as signal transduction, cytoskeleton dynamics and intracellular trafficking. Guanine-nucleotide-exchange factors (GEFs) positively regulate these GTP-binding proteins in response to a variety of signals. GEFs catalyze the dissociation of GDP from the inactive GTP-binding proteins. GTP can then bind and induce structural changes that allow interaction with effectors.

 469-575 6.40e-48

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.

first histone-fold domain found in son of sevenless homolog 1 (SOS-1) and similar proteins; SOS-1 is a guanine nucleotide exchange factor for Ras that binds to GRB2. It promotes the exchange of Ras-bound GDP by GTP. It is a catalytic component of a trimeric complex that participates in transduction of signals from Ras to Rac, by promoting the Rac-specific guanine nucleotide exchange factor (GEF) activity. SOS-1 contains tandem histone folds at the N-terminal region. The model corresponds to the first repeat.

 469-575 6.40e-48

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.

first histone-fold domain found in son of sevenless homolog 1 (SOS-1) and similar proteins; SOS-1 is a guanine nucleotide exchange factor for Ras that binds to GRB2. It promotes the exchange of Ras-bound GDP by GTP. It is a catalytic component of a trimeric complex that participates in transduction of signals from Ras to Rac, by promoting the Rac-specific guanine nucleotide exchange factor (GEF) activity. SOS-1 contains tandem histone folds at the N-terminal region. The model corresponds to the first repeat.

 635-769 2.35e-34

Guanine nucleotide exchange factor for Ras-like GTPases; N-terminal domain (RasGef_N), also called REM domain (Ras exchanger motif). This domain is common in nucleotide exchange factors for Ras-like small GTPases and is typically found immediately N-terminal to the RasGef (Cdc25-like) domain. REM contacts the GTPase and is assumed to participate in the catalytic activity of the exchange factor. Proteins with the REM domain include Sos1 and Sos2, which relay signals from tyrosine-kinase mediated signalling to Ras, RasGRP1-4, RasGRF1,2, CNrasGEF, and RAP-specific nucleotide exchange factors, to name a few.

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.

 806-1045 6.11e-75

Guanine nucleotide exchange factor for Ras-like small GTPases. Small GTP-binding proteins of the Ras superfamily function as molecular switches in fundamental events such as signal transduction, cytoskeleton dynamics and intracellular trafficking. Guanine-nucleotide-exchange factors (GEFs) positively regulate these GTP-binding proteins in response to a variety of signals. GEFs catalyze the dissociation of GDP from the inactive GTP-binding proteins. GTP can then bind and induce structural changes that allow interaction with effectors.

 469-575 6.40e-48

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.

Guanine nucleotide exchange factor for Ras-like GTPases; N-terminal domain (RasGef_N), also called REM domain (Ras exchanger motif). This domain is common in nucleotide exchange factors for Ras-like small GTPases and is typically found immediately N-terminal to the RasGef (Cdc25-like) domain. REM contacts the GTPase and is assumed to participate in the catalytic activity of the exchange factor. Proteins with the REM domain include Sos1 and Sos2, which relay signals from tyrosine-kinase mediated signalling to Ras, RasGRP1-4, RasGRF1,2, CNrasGEF, and RAP-specific nucleotide exchange factors, to name a few.

 449-572 1.53e-17

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.

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.

 475-571 2.20e-08

FYVE, RhoGEF and PH domain containing/faciogenital dysplasia proteins 1-4 and similar 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. 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. They play different roles to regulate cellular functions, even though their intracellular levels are tightly controlled by the same destruction pathway. 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.

 142-219 2.67e-07

histone-fold domain found in histone H2A and similar proteins; Histone H2A is the core component of the nucleosome, which wraps and compacts DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers.

 441-568 2.77e-07

Pleckstrin homology domain-containing family G members 1, 2, and 3 pleckstrin homology (PH) domain; PLEKHG1 (also called ARHGEF41), PLEKHG2 (also called ARHGEF42 or CLG/common-site lymphoma/leukemia guanine nucleotide exchange factor2), and PLEKHG3 (also called ARHGEF43) have RhoGEF DH/double-homology domains in tandem with a PH domain which is involved in phospholipid binding. They function as a guanine nucleotide exchange factor (GEF) and are involved in the regulation of Rho protein signal transduction. Mutations in PLEKHG1 have been associated panic disorder (PD), an anxiety disorder characterized by panic attacks and anticipatory anxiety. 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.

 485-571 6.66e-06

Vav pleckstrin homology (PH) domain; Vav acts as a guanosine nucleotide exchange factor (GEF) for Rho/Rac proteins. They control processes including T cell activation, phagocytosis, and migration of cells. The Vav subgroup of Dbl GEFs consists of three family members (Vav1, Vav2, and Vav3) in mammals. Vav1 is preferentially expressed in the hematopoietic system, while Vav2 and Vav3 are described by broader expression patterns. Mammalian Vav proteins consist of a calponin homology (CH) domain, an acidic region, a catalytic Dbl homology (DH) domain, a PH domain, a zinc finger cysteine rich domain (C1/CRD), and an SH2 domain, flanked by two SH3 domains. In invertebrates such as Drosophila and C. elegans, Vav is missing the N-terminal SH3 domain. The DH domain is involved in RhoGTPase recognition and selectivity and stimulates the reorganization of the switch regions for GDP/GTP exchange. The PH domain is implicated in directing membrane localization, allosteric regulation of guanine nucleotide exchange activity, and as a phospholipid- dependent regulator of GEF activity. Vavs bind RhoGTPases including Rac1, RhoA, RhoG, and Cdc42, while other members of the GEF family are specific for a single RhoGTPase. This promiscuity is thought to be a result of its CRD. 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.polarized. PH domains also have diverse functions. They are often involved in targeting proteins to the plasma membrane, but only a few (less than 10%) display strong specificity in binding inositol phosphates. 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.

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). 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.

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. 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.

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.

Obscurin pleckstrin homology (PH) domain; Obscurin (also called Obscurin-RhoGEF; Obscurin-myosin light chain kinase/Obscurin-MLCK) is a giant muscle protein that is concentrated at the peripheries of Z-disks and M-lines. It binds small ankyrin I, a component of the sarcoplasmic reticulum (SR) membrane. It is associated with the contractile apparatus through binding with titin and sarcomeric myosin. It plays important roles in the organization and assembly of the myofibril and the SR. Obscurin has been observed as alternatively-spliced isoforms. The major isoform in sleletal muscle, approximately 800 kDa in size, is composed of many adhesion modules and signaling domains. It harbors 49 Ig and 2 FNIII repeats at the N-terminues, a complex middle region with additional Ig domains, an IQ motif, and a conserved SH3 domain near RhoGEF and PH domains, and a non-modular C-terminus with phosphorylation motifs. The obscurin gene also encodes two kinase domains, which are not part of the 800 kDa form of the protein, but is part of smaller spliced products that present in heart muscle. 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.

p63RhoGEF pleckstrin homology (PH) domain, repeat 2; The guanine nucleotide exchange factor p63RhoGEF is an effector of the heterotrimeric G protein, Galphaq and linking Galphaq-coupled receptors (GPCRs) to the activation of RhoA. The Dbl(DH) and PH domains of p63RhoGEF interact with the effector-binding site and the C-terminal region of Galphaq and appear to relieve autoinhibition of the catalytic DH domain by the PH domain. Trio, Duet, and p63RhoGEF are shown to constitute a family of Galphaq effectors that appear to activate RhoA both in vitro and in intact cells. Dbs is a guanine nucleotide exchange factor (GEF), which contains spectrin repeats, a rhoGEF (DH) domain and a PH domain. The Dbs PH domain participates in binding to both the Cdc42 and RhoA GTPases. Trio plays an essential role in regulating the actin cytoskeleton during axonal guidance and branching. Trio is a multidomain signaling protein that contains two RhoGEF(DH)-PH domains in tandem. 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.

FERM, RhoGEF and pleckstrin domain-containing protein 1 and related proteins Pleckstrin Homology (PH) domain, repeat 1; 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 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. 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.
