Pleckstrin homology-like domain; The PH-like family includes the PH domain, both the Shc-like and IRS-like PTB domains, the ran-binding domain, the EVH1 domain, a domain in neurobeachin and the third domain of FERM. All of these domains have a PH fold, but lack significant sequence similarity. They are generally involved in targeting to protein to the appropriate cellular location or interacting with a binding partner. This domain family possesses multiple functions including the ability to bind inositol phosphates and to other proteins.

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, RhoGEF and PH domain containing/faciogenital dysplasia protein 5, 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. 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.

FYVE-like domain found in FYVE, RhoGEF and PH domain-containing protein 5 (FGD5) and similar proteins; FGD5, also termed zinc finger FYVE domain-containing protein 23, is an endothelial cell (EC)-specific guanine nucleotide exchange factor (GEF) that regulates endothelial adhesion, survival, and angiogenesis by modulating phosphatidylinositol 3-kinase signaling. It functions as a novel genetic regulator of vascular pruning by activation of endothelial cell-targeted apoptosis. 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.

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 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 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.

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.

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.

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.

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.

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.

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. 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.

Breakpoint Cluster Region-related pleckstrin homology (PH) domain; The BCR gene is one of the two genes in the BCR-ABL complex, which is associated with the Philadelphia chromosome, a product of a reciprocal translocation between chromosomes 22 and 9. BCR is a GTPase-activating protein (GAP) for RAC1 (primarily) and CDC42. The Dbl region of BCR has the most RhoGEF activity for Cdc42, and less activity towards Rac and Rho. Since BCR possesses both GAP and GEF activities, it may function to temporally regulate the activity of these GTPases. It also displays serine/threonine kinase activity. The BCR protein contains multiple domains including an N-terminal kinase domain, a RhoGEF domain, a PH domain, a C1 domain, a C2 domain, and a C-terminal RhoGAP domain. ABR, a related smaller protein, is structurally similar to BCR, but lacks the N-terminal kinase domain and has GAP activity for both Rac and Cdc42. 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.

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.

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.
