 2-262 4.75e-178

The F-BAR (FES-CIP4 Homology and Bin/Amphiphysin/Rvs) domain of FCH domain Only 1 protein; F-BAR domains are dimerization modules that bind and bend membranes and are found in proteins involved in membrane dynamics and actin reorganization. FCH domain Only 1 (FCHO1) may be involved in clathrin-coated vesicle formation. It contains an N-terminal F-BAR domain and a C-terminal domain of unknown function named SAFF which is also present in FCHO2 and endophilin interacting protein 1. F-BAR domains form banana-shaped dimers with a positively-charged concave surface that binds to negatively-charged lipid membranes. They can induce membrane deformation in the form of long tubules.

AP_MHD_Cterm super family cl10970

 603-864 2.06e-145

C-terminal domain of adaptor protein (AP) complexes medium mu subunits and its homologs (MHD); This family corresponds to the C-terminal domain of heterotetrameric AP complexes medium mu subunits and its homologs existing in monomeric stonins, delta-subunit of the heteroheptameric coat protein I (delta-COPI), a protein encoded by a pro-death gene referred as MuD (also known as MUDENG, mu-2 related death-inducing gene), an endocytic adaptor syp1, the mammalian FCH domain only proteins (FCHo1/2), SH3-containing GRB2-like protein 3-interacting protein 1 (SGIP1), and related proteins. AP complexes participate in the formation of intracellular coated transport vesicles and select cargo molecules for incorporation into the coated vesicles in the late secretory and endocytic pathways. Stonins have been characterized as clathrin-dependent AP-2 mu chain related factors and may act as cargo-specific sorting adaptors in endocytosis. Coat protein complex I (COPI)-coated vesicles function in the early secretory pathway. They mediate the retrograde transport from the Golgi to the ER, and intra-Golgi transport. MuD is distantly related to the C-terminal domain of mu2 subunit of AP-2. It is able to induce cell death by itself and plays an important role in cell death in various tissues. Syp1 represents a novel type of endocytic adaptor protein that participates in endocytosis, promotes vesicle tabulation, and contributes to cell polarity and stress responses. It shares the same domain architecture with its two ubiquitously expressed mammalian counterparts, FCHo1/2, which represent key initial proteins ultimately controlling cellular nutrient uptake, receptor regulation, and synaptic vesicle retrieval. They bind specifically to the plasma membrane and recruit the scaffold proteins eps15 and intersectin, which subsequently engage the adaptor complex AP2 and clathrin, leading to coated vesicle formation. Another mammalian neuronal-specific protein SGIP1 does have a C-terminal MHD and has been classified into this family as well. It is an endophilin-interacting protein that plays an obligatory role in the regulation of energy homeostasis. It is also involved in clathrin-mediated endocytosis by interacting with phospholipids and eps15.

FCHo1_MHD cd09268
mu-homology domain (MHD) of F-BAR domain-containing Fer/Cip4 homology domain-only protein 1 ...
 603-864 2.06e-145

mu-homology domain (MHD) of F-BAR domain-containing Fer/Cip4 homology domain-only protein 1 (FCH domain only 1 or FCHo1, also known as KIAA0290) and similar proteins; This family corresponds to the MHD found in ubiquitously expressed mammalian membrane-sculpting FCHo1 and similar proteins. FCHo1 represents a key initial protein that ultimately controls cellular nutrient uptake, receptor regulation, and synaptic vesicle retrieval. It is required for plasma membrane clathrin-coated vesicle (CCV) budding and marks sites of CCV formation. It binds specifically to the plasma membrane and recruits the scaffold proteins eps15 and intersectin, which subsequently engage the adaptor complex AP2 and clathrin, leading to coated vesicle formation. FCHo1 contains an N-terminal EFC/F-BAR domain, a proline-rich domain (PRD) in the middle region, and a C-terminal MHD. The crescent-shaped EFC/F-BAR domain can form an antiparallel dimer structure that binds PtdIns(4,5)P2-enriched membranes and can polymerize into rings to generate membrane tubules. The MHD is structurally related to the cargo-binding mu2 subunit of adaptor complex 2 (AP-2) and is responsible for the binding of eps15 and intersectin. Unlike other F-BAR domain containing proteins, FCHo1 has neither the Src homology 3 (SH3) domain nor any other known domain for interaction with dynamin and actin cytoskeleton. However, it can periodically accumulate at the budding site of clathrin. FCHo1 may utilize a unique action mode for vesicle formation as compared with other F-BAR proteins.

 602-862 2.05e-73

Muniscin C-terminal mu homology domain; The muniscins are a family of endocytic adaptors that is conserved from yeast to humans.This C-terminal domain is structurally similar to mu homology domains, and is the region of the muniscin proteins involved in the interactions with the endocytic adaptor-scaffold proteins Ede1-eps15. This interaction influences muniscin localization. The muniscins provide a combined adaptor-membrane-tubulation activity that is important for regulating endocytosis.

Fes/CIP4, and EFC/F-BAR homology domain; Alignment extended from. Highly alpha-helical. The cytosolic endocytic adaptor proteins in fungi carry this domain at the N-terminus; several of these have been referred to as muniscin proteins. These N-terminal BAR, N-BAR, and EFC/F-BAR domains are found in proteins that regulate membrane trafficking events by inducing membrane tubulation. The domain dimerizes into a curved structure that binds to liposomes and either senses or induces the curvature of the membrane bilayer to cause biophysical changes to the shape of the bilayer; it also thereby recruits other trafficking factors, such as the GTPase dynamin. Most EFC/F-BAR domain-family members localize to actin-rich structures.

 603-864 2.06e-145

mu-homology domain (MHD) of F-BAR domain-containing Fer/Cip4 homology domain-only protein 1 (FCH domain only 1 or FCHo1, also known as KIAA0290) and similar proteins; This family corresponds to the MHD found in ubiquitously expressed mammalian membrane-sculpting FCHo1 and similar proteins. FCHo1 represents a key initial protein that ultimately controls cellular nutrient uptake, receptor regulation, and synaptic vesicle retrieval. It is required for plasma membrane clathrin-coated vesicle (CCV) budding and marks sites of CCV formation. It binds specifically to the plasma membrane and recruits the scaffold proteins eps15 and intersectin, which subsequently engage the adaptor complex AP2 and clathrin, leading to coated vesicle formation. FCHo1 contains an N-terminal EFC/F-BAR domain, a proline-rich domain (PRD) in the middle region, and a C-terminal MHD. The crescent-shaped EFC/F-BAR domain can form an antiparallel dimer structure that binds PtdIns(4,5)P2-enriched membranes and can polymerize into rings to generate membrane tubules. The MHD is structurally related to the cargo-binding mu2 subunit of adaptor complex 2 (AP-2) and is responsible for the binding of eps15 and intersectin. Unlike other F-BAR domain containing proteins, FCHo1 has neither the Src homology 3 (SH3) domain nor any other known domain for interaction with dynamin and actin cytoskeleton. However, it can periodically accumulate at the budding site of clathrin. FCHo1 may utilize a unique action mode for vesicle formation as compared with other F-BAR proteins.

 603-864 7.15e-137

Mu-homology domain (MHD) of endocytic adaptor protein (AP), Syp1; This family corresponds to the MHD found in the metazoan counterparts of yeast Syp1, which includes two ubiquitously expressed membrane-sculpting F-BAR domain-containing Fer/Cip4 homology domain-only proteins 1 and 2 (FCH domain only 1 and 2, or FCHo1/FCHo2), neuronal-specific SH3-containing GRB2-like protein 3-interacting protein 1 (SGIP1), and related uncharacterized proteins. FCHo1/FCHo2 represent key initial proteins ultimately controlling cellular nutrient uptake, receptor regulation, and synaptic vesicle retrieval. They are required for plasma membrane clathrin-coated vesicle (CCV) budding and marked sites of CCV formation. They bind specifically to the plasma membrane and recruit the scaffold proteins eps15 and intersectin, which subsequently engage the adaptor complex AP2 and clathrin, leading to coated vesicle formation. Both FCHo1/FCHo2 contain an N-terminal EFC/F-BAR domain that induces membrane tabulation, a proline-rich domain (PRD) in the middle region, and a C-terminal MHD responsible for the binding of eps15 and intersectin. Another mammalian neuronal-specific protein, neuronal-specific transcript Scr homology 3 (SH3)-domain growth factor receptor-bound 2 (GRB2)-like (endophilin) interacting protein 1 [SGIP1] does not contain EFC/F-BAR domain, but does have a PRD and a C-terminal MHD and has been classified into this family as well. SGIP1 is an endophilin-interacting protein that plays an obligatory role in the regulation of energy homeostasis. It is also involved in clathrin-mediated endocytosis by interacting with phospholipids and eps15.

 602-862 2.05e-73

Muniscin C-terminal mu homology domain; The muniscins are a family of endocytic adaptors that is conserved from yeast to humans.This C-terminal domain is structurally similar to mu homology domains, and is the region of the muniscin proteins involved in the interactions with the endocytic adaptor-scaffold proteins Ede1-eps15. This interaction influences muniscin localization. The muniscins provide a combined adaptor-membrane-tubulation activity that is important for regulating endocytosis.

 603-864 2.33e-35

Mu-homology domain (MHD) of muniscins adaptor proteins (AP) and similar proteins; This family corresponds to the MHD found in muniscins, a novel family of endocytic adaptor proteins. The term, muniscins, has been assigned to name the MHD of proteins with both EFC/F-BAR domain and MHD. These two domains are responsible for the membrane-tubulation activity associated with transmembrane cargo proteins. Members in this family include an endocytic adaptor Syp1, the mammalian FCH domain only proteins (FCHo1/2), SH3-containing GRB2-like protein 3-interacting protein 1 (SGIP1), and related uncharacterized proteins. Syp1 is a poorly characterized yeast protein with multiple biological functions. Syp1 contains an N-terminal EFC/F-BAR domain that induces membrane tabulation, a proline-rich domain (PRD) in the middle region, and a C-terminal MHD that can directly binds to the endocytic adaptor/scaffold protein Ede1 or a transmembrane stress sensor cargo protein Mid2. Thus, Syp1 represents a novel type of endocytic adaptor protein that participates in endocytosis, promotes vesicle tabulation, and contributes to cell polarity and stress response. Syp1 shares the same domain architecture with its two ubiquitously expressed mammalian counterparts, the membrane-sculpting F-BAR domain-containing Fer/Cip4 homology domain-only proteins 1 and 2 (FCHo1/2). FCHo1/2 represent key initial proteins ultimately controlling cellular nutrient uptake, receptor regulation, and synaptic vesicle retrieval. They are required for plasma membrane clathrin-coated vesicle (CCV) budding and marked sites of CCV formation. They bind specifically to the plasma membrane and recruit the scaffold proteins eps15 and intersectin, which subsequently engage the adaptor complex AP2 and clathrin, leading to coated vesicle formation. Another mammalian neuronal-specific protein, neuronal-specific transcript Scr homology 3 (SH3)-domain growth factor receptor-bound 2 (GRB2)-like (endophilin) interacting protein 1 [SGIP1] does not contain EFC/F-BAR domain, but does have a PRD and a C-terminal MHD and has been classified into this family as well. SGIP1 is an endophilin-interacting protein that plays an obligatory role in the regulation of energy homeostasis. It is also involved in clathrin-mediated endocytosis by interacting with phospholipids and eps15.

The Extended FES-CIP4 Homology (FCH) or F-BAR (FCH and Bin/Amphiphysin/Rvs) domain, a dimerization module that binds and bends membranes; F-BAR domains are dimerization modules that bind and bend membranes and are found in proteins involved in membrane dynamics and actin reorganization. F-BAR domain containing proteins, also known as Pombe Cdc15 homology (PCH) family proteins, include Fes and Fer tyrosine kinases, PACSINs/Syndapins, FCHO, PSTPIP, CIP4-like proteins and srGAPs. Many members also contain an SH3 domain and play roles in endocytosis. F-BAR domains form banana-shaped dimers with a positively-charged concave surface that binds to negatively-charged lipid membranes. They can induce membrane deformation in the form of long tubules. These tubules have diameters larger than those observed with N-BARs. The F-BAR domains of some members such as NOSTRIN and Rgd1 are important for the subcellular localization of the protein.

The F-BAR (FES-CIP4 Homology and Bin/Amphiphysin/Rvs) domain of Proline-Serine-Threonine Phosphatase-Interacting Proteins; F-BAR domains are dimerization modules that bind and bend membranes and are found in proteins involved in membrane dynamics and actin reorganization. Vetebrates contain two Proline-Serine-Threonine Phosphatase-Interacting Proteins (PSTPIPs), PSTPIP1 and PSTPIP2. PSTPIPs are mainly expressed in hematopoietic cells and are involved in the regulation of cell adhesion and motility. Mutations in PSTPIPs have been shown to cause autoinflammatory disorders. PSTPIP1 contains an N-terminal F-BAR domain, PEST motifs, and a C-terminal SH3 domain, while PSTPIP2 contains only the N-terminal F-BAR domain. F-BAR domains form banana-shaped dimers with a positively-charged concave surface that binds to negatively-charged lipid membranes. They can induce membrane deformation in the form of long tubules.

The F-BAR (FES-CIP4 Homology and Bin/Amphiphysin/Rvs) domain of Growth Arrest Specific protein 7; F-BAR domains are dimerization modules that bind and bend membranes and are found in proteins involved in membrane dynamics and actin reorganization. Growth Arrest Specific protein 7 (GAS7) is mainly expressed in the brain and is required for neurite outgrowth. It may also play a role in the protection and migration of embryonic stem cells. Treatment-related acute myeloid leukemia (AML) has been reported resulting from mixed-lineage leukemia (MLL)-GAS7 translocations as a complication of primary cancer treatment. GAS7 contains an N-terminal SH3 domain, followed by a WW domain, and a central F-BAR domain. F-BAR domains form banana-shaped dimers with a positively-charged concave surface that binds to negatively-charged lipid membranes. They can induce membrane deformation in the form of long tubules.

Fes/CIP4, and EFC/F-BAR homology domain; Alignment extended from. Highly alpha-helical. The cytosolic endocytic adaptor proteins in fungi carry this domain at the N-terminus; several of these have been referred to as muniscin proteins. These N-terminal BAR, N-BAR, and EFC/F-BAR domains are found in proteins that regulate membrane trafficking events by inducing membrane tubulation. The domain dimerizes into a curved structure that binds to liposomes and either senses or induces the curvature of the membrane bilayer to cause biophysical changes to the shape of the bilayer; it also thereby recruits other trafficking factors, such as the GTPase dynamin. Most EFC/F-BAR domain-family members localize to actin-rich structures.

The F-BAR (FES-CIP4 Homology and Bin/Amphiphysin/Rvs) domain of Proline-Serine-Threonine Phosphatase-Interacting Protein 2; F-BAR domains are dimerization modules that bind and bend membranes and are found in proteins involved in membrane dynamics and actin reorganization. Proline-Serine-Threonine Phosphatase-Interacting Protein 2 (PSTPIP2), also known as Macrophage Actin-associated tYrosine Phosphorylated protein (MAYP), is mostly expressed in hematopoietic cells but is also expressed in the brain. It is involved in regulating cell adhesion and motility. Mutations in the gene encoding murine PSTPIP2 can cause autoinflammatory disorders such as chronic multifocal osteomyelitis and macrophage autoinflammatory disease. PSTPIP2 contains an N-terminal F-BAR domain and lacks the PEST motifs and SH3 domain that are found in PSTPIP1. F-BAR domains form banana-shaped dimers with a positively-charged concave surface that binds to negatively-charged lipid membranes. They can induce membrane deformation in the form of long tubules.

 5-212 1.01e-14

The F-BAR (FES-CIP4 Homology and Bin/Amphiphysin/Rvs) domain of Nitric Oxide Synthase TRaffic INducer (NOSTRIN); F-BAR domains are dimerization modules that bind and bend membranes and are found in proteins involved in membrane dynamics and actin reorganization. Nitric Oxide Synthase TRaffic INducer (NOSTRIN) is expressed in endothelial and epithelial cells and is involved in the regulation, trafficking and targeting of endothelial NOS (eNOS). NOSTRIN facilitates the endocytosis of eNOS by coordinating the functions of dynamin and the Wiskott-Aldrich syndrome protein (WASP). Increased expression of NOSTRIN may be correlated to preeclampsia. NOSTRIN contains an N-terminal F-BAR domain and a C-terminal SH3 domain. F-BAR domains form banana-shaped dimers with a positively-charged concave surface that binds to negatively-charged lipid membranes. They can induce membrane deformation in the form of long tubules. The F-BAR domain of NOSTRIN is necessary and sufficient for its membrane association and is responsible for its subcellular localization.

The F-BAR (FES-CIP4 Homology and Bin/Amphiphysin/Rvs) domain of Schizosaccharomyces pombe Cdc15, and similar proteins; F-BAR domains are dimerization modules that bind and bend membranes and are found in proteins involved in membrane dynamics and actin reorganization. This subfamily is composed of Schizosaccharomyces pombe Cdc15 and Imp2, and similar proteins. These proteins contain an N-terminal F-BAR domain and a C-terminal SH3 domain. S. pombe Cdc15 and Imp2 play both distinct and overlapping roles in the maintenance and strengthening of the contractile ring at the division site, which is required in cell division. Cdc15 is a component of the actomyosin ring and is required in normal cytokinesis. Imp2 colocalizes with the medial ring during septation and is required for normal septation. F-BAR domains form banana-shaped dimers with a positively-charged concave surface that binds to negatively-charged lipid membranes. They can induce membrane deformation in the form of long tubules.

The F-BAR (FES-CIP4 Homology and Bin/Amphiphysin/Rvs) domain of Proline-Serine-Threonine Phosphatase-Interacting Protein 1; F-BAR domains are dimerization modules that bind and bend membranes and are found in proteins involved in membrane dynamics and actin reorganization. Proline-Serine-Threonine Phosphatase-Interacting Protein 1 (PSTPIP1), also known as CD2 Binding Protein 1 (CD2BP1), is mainly expressed in hematopoietic cells. It is a binding partner of the cell surface receptor CD2 and PTP-PEST, a tyrosine phosphatase which functions in cell motility and Rac1 regulation. It also plays a role in the activation of the Wiskott-Aldrich syndrome protein (WASP), which couples actin rearrangement and T cell activation. Mutations in the gene encoding PSTPIP1 cause the autoinflammatory disorder known as PAPA (pyogenic sterile arthritis, pyoderma gangrenosum, and acne) syndrome. PSTPIP1 contains an N-terminal F-BAR domain, PEST motifs, and a C-terminal SH3 domain. F-BAR domains form banana-shaped dimers with a positively-charged concave surface that binds to negatively-charged lipid membranes. They can induce membrane deformation in the form of long tubules.

 8-231 2.10e-05

The Bin/Amphiphysin/Rvs (BAR) domain, a dimerization module that binds membranes and detects membrane curvature; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions including organelle biogenesis, membrane trafficking or remodeling, and cell division and migration. Mutations in BAR containing proteins have been linked to diseases and their inactivation in cells leads to altered membrane dynamics. A BAR domain with an additional N-terminal amphipathic helix (an N-BAR) can drive membrane curvature. These N-BAR domains are found in amphiphysins and endophilins, among others. BAR domains are also frequently found alongside domains that determine lipid specificity, such as the Pleckstrin Homology (PH) and Phox Homology (PX) domains which are present in beta centaurins (ACAPs and ASAPs) and sorting nexins, respectively. A FES-CIP4 Homology (FCH) domain together with a coiled coil region is called the F-BAR domain and is present in Pombe/Cdc15 homology (PCH) family proteins, which include Fes/Fes tyrosine kinases, PACSIN or syndapin, CIP4-like proteins, and srGAPs, among others. The Inverse (I)-BAR or IRSp53/MIM homology Domain (IMD) is found in multi-domain proteins, such as IRSp53 and MIM, that act as scaffolding proteins and transducers of a variety of signaling pathways that link membrane dynamics and the underlying actin cytoskeleton. BAR domains form dimers that bind to membranes, induce membrane bending and curvature, and may also be involved in protein-protein interactions. The I-BAR domain induces membrane protrusions in the opposite direction compared to classical BAR and F-BAR domains, which produce membrane invaginations. BAR domains that also serve as protein interaction domains include those of arfaptin and OPHN1-like proteins, among others, which bind to Rac and Rho GAP domains, respectively.

 627-829 6.53e-05

mu-homology domain (MHD) of adaptor protein (AP), Syp1, and related proteins; This family corresponds to the MHD found in a novel endocytic adaptor Syp1 and related proteins. Syp1 is a poorly characterized yeast protein with multiple biological functions. It was originally identified as a suppressor of a yeast profiling deletion and later as a suppressor of arf3delta (Arf3 is the yeast homologue of Arf6, a mammalian regulator of endocytosis). Syp1 can bind to septins and physically link with cell polarity factors. It also directly binds to the endocytic adaptor/scaffold protein Ede1, and plays a role in endocytosis. Further studies show that Syp1 is itself an endocytic adaptor protein contributing to stress responses. Its mu-homology domain at the C-terminus binds to the cargo protein Mid2, a transmembrane stress sensor protein, and mediates Mid2 internalization. In addition, Syp1 contains an EFC/F-BAR domain which can induce membrane tabulation.

 24-198 2.46e-04

The F-BAR (FES-CIP4 Homology and Bin/Amphiphysin/Rvs) domain of Protein kinase C and Casein kinase Substrate in Neurons 3 (PACSIN3); F-BAR domains are dimerization modules that bind and bend membranes and are found in proteins involved in membrane dynamics and actin reorganization. Protein kinase C and Casein kinase Substrate in Neurons (PACSIN) proteins, also called Synaptic dynamin-associated proteins (Syndapins), act as regulators of cytoskeletal and membrane dynamics. Vetebrates harbor three isoforms with distinct expression patterns and specific functions. PACSIN 3 or Syndapin III is expressed ubiquitously and regulates glucose uptake in adipocytes through its role in GLUT1 trafficking. It also modulates the subcellular localization and stimulus-specific function of the cation channel TRPV4. PACSIN 3 contains an N-terminal F-BAR domain and a C-terminal SH3 domain. F-BAR domains form banana-shaped dimers with a positively-charged concave surface that binds to negatively-charged lipid membranes. They can induce membrane deformation in the form of long tubules.

 24-178 3.42e-04

The F-BAR (FES-CIP4 Homology and Bin/Amphiphysin/Rvs) domain of Slit-Robo GTPase Activating Proteins; F-BAR domains are dimerization modules that bind and bend membranes and are found in proteins involved in membrane dynamics and actin reorganization. Slit-Robo GTPase Activating Proteins (srGAPs) are Rho GAPs that interact with Robo1, the transmembrane receptor of Slit proteins. Slit proteins are secreted proteins that control axon guidance and the migration of neurons and leukocytes. Vertebrates contain three isoforms of srGAPs, all of which are expressed during embryonic and early development in the nervous system but with different localization and timing. srGAPs contain an N-terminal F-BAR domain, a Rho GAP domain, and a C-terminal SH3 domain. F-BAR domains form banana-shaped dimers with a positively-charged concave surface that binds to negatively-charged lipid membranes. They can induce membrane deformation in the form of long tubules.

 711-834 1.75e-03

C-terminal domain of medium Mu3 subunit in adaptor protein (AP) complex AP-3; AP complexes participate in the formation of intracellular coated transport vesicles and select cargo molecules for incorporation into the coated vesicles in the late secretory and endocytic pathways. There are four AP complexes, AP-1, AP-2, AP-3, and AP-4, described in various eukaryotic organisms. Each AP complex consists of four subunits: two large chains (one each of gamma/alpha/delta/epsilon and beta1-4, respectively), a medium mu chain (mu1-4), and a small sigma chain (sigma1-4). Each of the four subunits from the different AP complexes exhibits similarity with each other. This family corresponds to the C-terminal domain of heterotetrameric adaptor protein complex 3 (AP-3) medium mu3 subunit, which includes two closely related homologs, mu3A (P47A, encoded by ap3m1) and mu1B (P47B, encoded by ap3m2). Mu3A is ubiquitously expressed, but mu3B is specifically expressed in neurons and neuroendocrine cells. AP-3 is particularly important for targeting integral membrane proteins to lysosomes and lysome-related organelles at trans-Golgi network (TGN) and/or endosomes, such as the yeast vacuole, fly pigment granules and mammalian melanosomes, platelet dense bodies and the secretory lysosomes of cytotoxic T lymphocytes. Unlike AP-1 and AP-2, which function in conjunction with clathrin which is a scaffolding protein participating in the formation of coated vesicles, the nature of the outer shell of AP-3 containing coats remains to be elucidated. Membrane-anchored cargo molecules interact with adaptors through short sorting signals in their cytosolic segments. Tyrosine-based endocytotic signals are one of the most important sorting signals. They are of the form Y-X-X-Phi, where Y is tyrosine, X is any amino acid and Phi is a bulky hydrophobic residue that can be Leu, Ile, Met, Phe, or Val. These kinds of sorting signals can be recognized by the C-terminal domain of AP-3 mu3 subunit, also known as Y-X-X-Phi signal-binding domain that contains two hydrophobic pockets, one for the tyrosine-binding and one for the bulky hydrophobic residue-binding.
