Catalytic inositol polyphosphate 5-phosphatase (INPP5c) domain of Type II inositol polyphosphate 5-phosphatase I, Oculocerebrorenal syndrome of Lowe 1, and related proteins; This subfamily contains the INPP5c domain of type II inositol polyphosphate 5-phosphatase I (INPP5B), Oculocerebrorenal syndrome of Lowe 1 (OCRL-1), and related proteins. It belongs to a family of Mg2+-dependent inositol polyphosphate 5-phosphatases, which hydrolyze the 5-phosphate from the inositol ring of various 5-position phosphorylated phosphoinositides (PIs) and inositol phosphates (IPs), and to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds. INPP5B and OCRL1 preferentially hydrolyze the 5-phosphate of phosphatidylinositol (4,5)- bisphosphate [PI(4,5)P2] and phosphatidylinositol (3,4,5)- trisphosphate [PI(3,4,5)P3]. INPP5B can also hydrolyze soluble inositol (1,4,5)-trisphosphate [I(1,4,5)P3] and inositol (1,3,4,5)-tetrakisphosphate [I(1,3,4,5)P4]. INPP5B participates in the endocytic pathway and in the early secretory pathway. In the latter, it may function in retrograde ERGIC (ER-to-Golgi intermediate compartment)-to-ER transport; it binds specific RAB proteins within the secretory pathway. In the endocytic pathway, it binds RAB5 and during endocytosis, may function in a RAB5-controlled cascade for converting PI(3,4,5)P3 to phosphatidylinositol 3-phosphate (PI3P). This cascade may link growth factor signaling and membrane dynamics. Mutation in OCRL1 is implicated in Lowe syndrome, an X-linked recessive multisystem disorder, which includes defects in eye, brain, and kidney function, and in Type 2 Dent's disease, a disorder with only the renal symptoms. OCRL-1 may have a role in membrane trafficking within the endocytic pathway and at the trans-Golgi network, and may participate in actin dynamics or signaling from endomembranes. OCRL1 and INPP5B have overlapping functions: deletion of both 5-phosphatases in mice is embryonic lethal, deletion of OCRL1 alone has no phenotype, and deletion of Inpp5b alone has only a mild phenotype (male sterility). Several of the proteins that interact with OCRL1 also bind INPP5B, for examples, inositol polyphosphate phosphatase interacting protein of 27kDa (IPIP27)A and B (also known as Ses1 and 2), and endocytic signaling adaptor APPL1. OCRL1, but not INPP5B, binds clathrin heavy chain, the plasma membrane AP2 adaptor subunit alpha-adaptin. In addition to this INPP5c domain, most proteins in this subfamily have a C-terminal RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain. : Pssm-ID: 197327 Cd Length: 292 Bit Score: 604.31 E-value: 0e+00

oculocerebrorenal syndrome of Lowe 1 Pleckstrin homology-like domain; OCRL1 (also called INPP5F, LOCR, NPHL2, or phosphatidylinositol polyphosphate 5-phosphatase) hydrolyzes phosphatidylinositol 4,5-bisphosphate (PtIns(4,5)P2) and the signaling molecule phosphatidylinositol 1,4,5-trisphosphate (PtIns(1,4,5)P3), and thereby modulates cellular signaling events. It interact with APPL1, FAM109A and FAM109B and several Rab GTPases which might both target them to the specific membranes and as well as stimulating the phosphatase activity. OCRL1 contains a PH domain and a Rho-GAP domain. Patients with Lowe syndrome suffer primarily from congenital cataracts, neonatal hypotonia, intellectual disability and Fanconi syndrome. Mutations in OCRL are also found in a subset of patients with type 2 Dent disease, who selectively suffer from renal proximal tubular dysfunction. 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.

Catalytic domain of inositol polyphosphate 5-phosphatases; Inositol polyphosphate 5-phosphatases (5-phosphatases) are signal-modifying enzymes, which hydrolyze the 5-phosphate from the inositol ring of specific 5-position phosphorylated phosphoinositides (PIs) and inositol phosphates (IPs), such as PI(4,5)P2, PI(3,4,5)P3, PI(3,5)P2, I(1,4,5)P3, and I(1,3,4,5)P4. These enzymes are Mg2+-dependent, and belong to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds. In addition to this INPP5c domain, 5-phosphatases often contain additional domains and motifs, such as the SH2 domain, the Sac-1 domain, the proline-rich domain (PRD), CAAX, RhoGAP (RhoGTPase-activating protein), and SKICH [SKIP (skeletal muscle- and kidney-enriched inositol phosphatase) carboxyl homology] domains, that are important for protein-protein interactions and/or for the subcellular localization of these enzymes. 5-phosphatases incorporate into large signaling complexes, and regulate diverse cellular processes including postsynaptic vesicular trafficking, insulin signaling, cell growth and survival, and endocytosis. Loss or gain of function of 5-phosphatases is implicated in certain human diseases. This family also contains a functionally unrelated nitric oxide transport protein, Cimex lectularius (bedbug) nitrophorin, which catalyzes a heme-assisted S-nitrosation of a proximal thiolate; the heme however binds at a site distinct from the active site of the 5-phosphatases.

Catalytic inositol polyphosphate 5-phosphatase (INPP5c) domain of Saccharomyces cerevisiae Inp51p, Inp52p, and Inp53p, and related proteins; This subfamily contains the INPP5c domain of three Saccharomyces cerevisiae synaptojanin-like inositol polyphosphate 5-phosphatases (INP51, INP52, and INP53), Schizosaccharomyces pombe synaptojanin (SPsynaptojanin), and related proteins. It belongs to a family of Mg2+-dependent inositol polyphosphate 5-phosphatases, which hydrolyze the 5-phosphate from the inositol ring of various 5-position phosphorylated phosphoinositides (PIs) and inositol phosphates (IPs), and to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds. In addition to this INPP5c domain, these proteins have an N-terminal catalytic Sac1-like domain (found in other proteins including the phophoinositide phosphatase Sac1p), and a C-terminal proline-rich domain (PRD). The Sac1 domain allows Inp52p and Inp53p to recognize and dephosphorylate a wider range of substrates including PI3P, PI4P, and PI(3,5)P2. The Sac1 domain of Inp51p is non-functional. Disruption of any two of INP51, INP52, and INP53, in S. cerevisiae leads to abnormal vacuolar and plasma membrane morphology. During hyperosmotic stress, Inp52p and Inp53p localize at actin patches, where they may facilitate the hydrolysis of PI(4,5)P2, and consequently promote actin rearrangement to regulate cell growth. SPsynaptojanin is also active against a range of soluble and lipid inositol phosphates, including I(1,4,5)P3, I(1,3,4,5)P4, I(1,4,5,6)P4, PI(4,5)P2, and PIP3. Transformation of S. cerevisiae with a plasmid expressing the SPsynaptojanin 5-phosphatase domain rescues inp51/inp52/inp53 triple-mutant strains.

Catalytic inositol polyphosphate 5-phosphatase (INPP5c) domain of synaptojanins; This subfamily contains the INPP5c domains of two human synaptojanins, synaptojanin 1 (Synj1) and synaptojanin 2 (Synj2), and related proteins. It belongs to a family of Mg2+-dependent inositol polyphosphate 5-phosphatases, which hydrolyze the 5-phosphate from the inositol ring of various 5-position phosphorylated phosphoinositides (PIs) and inositol phosphates (IPs). They belong to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds. Synj1 occurs as two main isoforms: a brain enriched 145 KDa protein (Synj1-145) and a ubiquitously expressed 170KDa protein (Synj1-170). Synj1-145 participates in clathrin-mediated endocytosis. The primary substrate of the Synj1-145 INPP5c domain is PI(4,5)P2, which it converts to PI4P. Synj1-145 may work with membrane curvature sensors/generators (such as endophilin) to remove PI(4,5)P2 from curved membranes. The recruitment of the INPP5c domain of Synj1-145 to endophilin-induced membranes leads to a fragmentation and condensation of these structures. The PI(4,5)P2 to PI4P conversion may cooperate with dynamin to produce membrane fission. In addition to this INPP5c domain, Synjs contain an N-terminal Sac1-like domain; the Sac1 domain can dephosphorylate a variety of phosphoinositides in vitro. Synj2 can hydrolyze phosphatidylinositol diphosphate (PIP2) to phosphatidylinositol phosphate (PIP). Synj2 occurs as multiple alternative splice variants in various tissues. These variants share the INPP5c domain and the Sac1 domain. Synj2A is recruited to the mitochondria via its interaction with OMP25 (a mitochondrial outer membrane protein). Synj2B is found at nerve terminals in the brain and at the spermatid manchette in testis. Synj2B undergoes further alternative splicing to give 2B1 and 2B2. In clathrin-mediated endocytosis, Synj2 participates in the formation of clathrin-coated pits, and perhaps also in vesicle decoating. Rac1 GTPase regulates the intracellular localization of Synj2 forms, but not Synj1. Synj2 may contribute to the role of Rac1 in cell migration and invasion, and is a potential target for therapeutic intervention in malignant tumors.

It belongs to a family of Mg2+-dependent inositol polyphosphate 5-phosphatases, which hydrolyze the 5-phosphate from the inositol ring of various 5-position phosphorylated phosphoinositides (PIs) and inositol phosphates (IPs), and to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds. Synj2 can hydrolyze phosphatidylinositol diphosphate (PIP2) to phosphatidylinositol phosphate (PIP). In addition to this INPP5c domain, these proteins contain an N-terminal Sac1-like domain; the Sac1 domain can dephosphorylate a variety of phosphoinositides in vitro. Synj2 occurs as multiple alternative splice variants in various tissues. These variants share the INPP5c domain and the Sac1 domain. Synj2A is recruited to the mitochondria via its interaction with OMP25, a mitochondrial outer membrane protein. Synj2B is found at nerve terminals in the brain and at the spermatid manchette in testis. Synj2B undergoes further alternative splicing to give 2B1 and 2B2. In clathrin-mediated endocytosis, Synj2 participates in the formation of clathrin-coated pits, and perhaps also in vesicle decoating. Rac1 GTPase regulates the intracellular localization of Synj2 forms, but not Synj1. Synj2 may contribute to the role of Rac1 in cell migration and invasion, and is a potential target for therapeutic intervention in malignant tumors.

Catalytic inositol polyphosphate 5-phosphatase (INPP5c) domain of synaptojanin 1; This subfamily contains the INPP5c domains of human synaptojanin 1 (Synj1) and related proteins. It belongs to a family of Mg2+-dependent inositol polyphosphate 5-phosphatases, which hydrolyze the 5-phosphate from the inositol ring of various 5-position phosphorylated phosphoinositides (PIs) and inositol phosphates (IPs), and to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds. Synj1 occurs as two main isoforms: a brain enriched 145 KDa protein (Synj1-145) and a ubiquitously expressed 170KDa protein (Synj1-170). Synj1-145 participates in clathrin-mediated endocytosis. The primary substrate of the Synj1-145 INPP5c domain is PI(4,5)P2, which it converts to PI4P. Synj1-145 may work with membrane curvature sensors/generators (such as endophilin) to remove PI(4,5)P2 from curved membranes. The recruitment of the INPP5c domain of Synj1-145 to endophilin-induced membranes leads to a fragmentation and condensation of these structures. The PI(4,5)P2 to PI4P conversion may cooperate with dynamin to produce membrane fission. In addition to this INPP5c domain, these proteins contain an N-terminal Sac1-like domain; the Sac1 domain can dephosphorylate a variety of phosphoinositides in vitro.

oculocerebrorenal syndrome of Lowe 1 Pleckstrin homology-like domain; OCRL1 (also called INPP5F, LOCR, NPHL2, or phosphatidylinositol polyphosphate 5-phosphatase) hydrolyzes phosphatidylinositol 4,5-bisphosphate (PtIns(4,5)P2) and the signaling molecule phosphatidylinositol 1,4,5-trisphosphate (PtIns(1,4,5)P3), and thereby modulates cellular signaling events. It interact with APPL1, FAM109A and FAM109B and several Rab GTPases which might both target them to the specific membranes and as well as stimulating the phosphatase activity. OCRL1 contains a PH domain and a Rho-GAP domain. Patients with Lowe syndrome suffer primarily from congenital cataracts, neonatal hypotonia, intellectual disability and Fanconi syndrome. Mutations in OCRL are also found in a subset of patients with type 2 Dent disease, who selectively suffer from renal proximal tubular dysfunction. 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.

SHIP1's enzymic activity is restricted to phosphatidylinositol 3,4,5-trisphosphate [PI (3,4,5)P3] and inositol-1,3,4,5- polyphosphate [I(1,3,4,5)P4]. It converts these two phosphoinositides to phosphatidylinositol 3,4-bisphosphate [PI (3,4)P2] and inositol-1,3,4-polyphosphate [I(1,3,4)P3], respectively. SHIP1 is a negative regulator of cell growth and plays a major part in mediating the inhibitory signaling in B cells; it is predominantly expressed in hematopoietic cells. In addition to this INPP5c domain, SHIP1 has an N-terminal SH2 domain, two NPXY motifs, and a C-terminal proline-rich region (PRD). SHIP1's phosphorylated NPXY motifs interact with proteins with phosphotyrosine binding (PTB) domains, and facilitate the translocation of SHIP1 to the plasma membrane to hydrolyze PI(3,4,5)P3. SHIP1 generally acts to oppose the activity of phosphatidylinositol 3-kinase (PI3K). It acts as a negative signaling molecule, reducing the levels of PI(3,4,5)P3, thereby removing the latter as a membrane-targeting signal for PH domain-containing effector molecules. SHIP1 may also, in certain contexts, amplify PI3K signals. SHIP1 and SHIP2 have little overlap in their in vivo functions. Pssm-ID: 197334 Cd Length: 307 Bit Score: 185.96 E-value: 1.55e-52

Its interacting partners include filamin/actin, p130Cas, Shc, Vinexin, Interesectin 1, and c-Jun NH2-terminal kinase (JNK)-interacting protein 1 (JIP1). A large variety of extracellular stimuli appear to lead to the tyrosine phosphorylation of SHIP2, including epidermal growth factor (EGF), platelet-derived growth factor (PDGF), insulin, macrophage colony-stimulating factor (M-CSF) and hepatocyte growth factor (HGF). SHIP2 is localized to the cytosol in quiescent cells; following growth factor stimulation and /or cell adhesion, it relocalizes to membrane ruffles. In addition to this INPP5c domain, SHIP2 has an N-terminal SH2 domain, a C-terminal proline-rich domain (PRD), which includes a WW-domain binding motif (PPLP), an NPXY motif and a sterile alpha motif (SAM) domain.

Its intracellular localization is chiefly cytosolic, with pronounced perinuclear/Golgi localization. INPP5E also has an N-terminal proline rich domain (PRD) and a C-terminal CAAX motif. This protein is expressed in a variety of tissues, including the breast, brain, testis, and haemopoietic cells. It is differentially expressed in several cancers, for example, it is up-regulated in cervical cancer and down-regulated in stomach cancer. It is a candidate target for therapeutics of obesity and related disorders, as it is expressed in the hypothalamus, and following insulin stimulation, it undergoes tyrosine phosphorylation, associates with insulin receptor substrate-1, -2, and PI3-kinase, and become active as a 5-phosphatase. INPP5E may play a role, along with other 5-phosphatases SHIP2 and SKIP, in regulating glucose homoeostasis and energy metabolism.

RhoGAP-ARHGAP11A: RhoGAP (GTPase-activator protein [GAP] for Rho-like small GTPases) domain of ArhGAP11A-like proteins. The mouse homolog of human ArhGAP11A has been detected as a gene exclusively expressed in immature ganglion cells, potentially playing a role in retinal development. The exact function of ArhGAP11A is unknown. Small GTPases cluster into distinct families, and all act as molecular switches, active in their GTP-bound form but inactive when GDP-bound. The Rho family of GTPases activates effectors involved in a wide variety of developmental processes, including regulation of cytoskeleton formation, cell proliferation and the JNK signaling pathway. GTPases generally have a low intrinsic GTPase hydrolytic activity but there are family-specific groups of GAPs that enhance the rate of GTP hydrolysis by several orders of magnitude.

RhoGAP_Graf: GTPase-activator protein (GAP) domain for Rho-like GTPases found in GRAF (GTPase regulator associated with focal adhesion kinase); Graf is a multi-domain protein, containing SH3 and PH domains, that binds focal adhesion kinase and influences cytoskeletal changes mediated by Rho proteins. Graf exhibits GAP activity toward RhoA and Cdc42, but only weakly activates Rac1. Small GTPases cluster into distinct families, and all act as molecular switches, active in their GTP-bound form but inactive when GDP-bound. The Rho family of GTPases activates effectors involved in a wide variety of developmental processes, including regulation of cytoskeleton formation, cell proliferation and the JNK signaling pathway. GTPases generally have a low intrinsic GTPase hydrolytic activity but there are family-specific groups of GAPs that enhance the rate of GTP hydrolysis by several orders of magnitude.
