The complex is responsible for synthesizing phosphatidylinositol 3,5-bisphosphate [PtdIns(3,5)P2] by catalyzing the phosphorylation of phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) on the fifth hydroxyl of the myo-inositol ring. 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. PIKfyve is vital in early embryonic development. It forms a complex with ArPIKfyve (associated regulator of PIKfyve) and SAC3 at the endomembranes, playing 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.

chaperonin_like superfamily. Chaperonins are involved in productive folding of proteins. They share a common general morphology, a double toroid of 2 stacked rings, each composed of 7-9 subunits. There are 2 main chaperonin groups. The symmetry of type I is seven-fold and they are found in eubacteria (GroEL) and in organelles of eubacterial descent (hsp60 and RBP). The symmetry of type II is eight- or nine-fold and they are found in archea (thermosome), thermophilic bacteria (TF55) and in the eukaryotic cytosol (CTT).

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.

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-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 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.

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.

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.

377-449 | 1.36e-03 | |||||||||
DEP (Dishevelled, Egl-10, and Pleckstrin) domain found in RGS (regulator of G-protein signaling) proteins of the subfamily R7. This subgroup contains RGS7, RGS6, RGS9 and RGS11. They share a common domain architecture, containing, beside the RGS domain, a DEP domain and a GGL (G-protein gamma subunit-like ) domain. RGS proteins are GTPase-activating (GAP) proteins of heterotrimeric G proteins by increasing the rate of GTP hydrolysis of the alpha subunit. The fungal homologs, like yeast Sst2, share a related common domain architecture, containing RGS and DEP domains. Sst2 has been identified as the principal regulator of mating pheromone signaling and recently the DEP domain of Sst2 has been shown to be necessary and sufficient to mediate receptor interaction.

TCP-1 (CTT or eukaryotic type II) chaperonin family, theta subunit. Chaperonins are involved in productive folding of proteins. They share a common general morphology, a double toroid of 2 stacked rings. In contrast to bacterial group I chaperonins (GroEL), each ring of the eukaryotic cytosolic chaperonin (CTT) consists of eight different, but homologous subunits. Their common function is to sequester nonnative proteins inside their central cavity and promote folding by using energy derived from ATP hydrolysis. The best studied in vivo substrates of CTT are actin and tubulin. Pssm-ID: 239457 [Multi-domain] Cd Length: 472 Bit Score: 42.98 E-value: 2.06e-03

FYVE-related domain found in RUN and FYVE domain-containing protein 3 (RUFY3) and similar proteins; RUFY3, also termed Rap2-interacting protein x (RIPx or RPIPx), or single axon-regulated protein (singar), is an N-terminal RUN domain and a C-terminal FYVE domain containing protein predominantly expressed in the brain. 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). Pssm-ID: 277283 [Multi-domain] Cd Length: 52 Bit Score: 37.40 E-value: 3.55e-03

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.

FYVE-like domain found in caspase regulator CARP1 and similar proteins; CARP1, also termed E3 ubiquitin-protein ligase RNF34, or caspases-8 and -10-associated RING finger protein 1, or FYVE-RING finger protein Momo, or RING finger homologous to inhibitor of apoptosis protein (RFI), or RING finger protein 34, or RING finger protein RIFF, is a nuclear protein that functions as a specific E3 ubiquitin ligase for the transcriptional coactivator PGC-1alpha, a master regulator of energy metabolism and adaptive thermogenesis in the brown fat cell, and negatively regulates brown fat cell metabolism. It is preferentially expressed in esophageal, gastric and colorectal cancers, suggesting a possible association with the development of the digestive tract cancers. It regulates the p53 signaling pathway through degrading 14-3-3 sigma and stabilizing MDM2. CARP1 does not localize to membranes in the cell and is 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, CARP1 has an altered sequence in the basic ligand binding patch and lack the WxxD (x for any residue) motif that is conserved only in phosphoinositide binding FYVE domains. Thus it belongs to a family of unique FYVE-type domains called FYVE-like domains. In addition to the N-terminal FYVE-like domain, CARP1 harbors a C-terminal RING domain.
