http://identifiers.org/unip...biopax3:commentFUNCTION: Generates phosphatidylinositol 3-phosphate (PtdIns3P) and phosphatidylinositol 3,4-bisphosphate (PtdIns(3,4)P2) that act as second messengers. Has a role in several intracellular trafficking events. Functions in insulin signaling and secretion. Required for translocation of the glucose transporter SLC2A4/GLUT4 to the plasma membrane and glucose uptake in response to insulin- mediated RHOQ activation. Regulates insulin secretion through two different mechanisms: involved in glucose-induced insulin secretion downstream of insulin receptor in a pathway that involves AKT1 activation and TBC1D4/AS160 phosphorylation, and participates in the late step of insulin granule exocytosis probably in insulin granule fusion. Synthesizes PtdIns3P in response to insulin signaling. Functions in clathrin-coated endocytic vesicle formation and distribution. Regulates dynamin- independent endocytosis, probably by recruiting EEA1 to internalizing vesicles. In neurosecretory cells synthesizes PtdIns3P on large dense core vesicles. Participates in calcium induced contraction of vascular smooth muscle by regulating myosin light chain (MLC) phosphorylation through a mechanism involving Rho kinase-dependent phosphorylation of the MLCP-regulatory subunit MYPT1. May play a role in the EGF signaling cascade. May be involved in mitosis and UV-induced damage response. Required for maintenance of normal renal structure and function by supporting normal podocyte function. CATALYTIC ACTIVITY: ATP + 1-phosphatidyl-1D-myo-inositol 4- phosphate = ADP + 1-phosphatidyl-1D-myo-inositol 3,4-bisphosphate. COFACTOR: Calcium or magnesium. Manganese cannot be used (By similarity). ENZYME REGULATION: Activated by clathrin (By similarity). Only slightly inhibited by wortmannin and LY294002. Activated by insulin. SUBUNIT: Interacts with ERBB2 and EGFR. Interacts with clathrin trimers (By similarity). SUBCELLULAR LOCATION: Cell membrane. Golgi apparatus. Cytoplasmic vesicle, clathrin-coated vesicle. Nucleus. Cytoplasm (By similarity). Note=Has a preference for membranes containing PtdIns(4,5)P2 or PtdIns(3,4)P2. ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q61194-1; Sequence=Displayed; Name=2; IsoId=Q61194-2; Sequence=VSP_015254; TISSUE SPECIFICITY: Detected in podocytes. PTM: Phosphorylated on Ser-261 during mitosis and upon UV irradiation; which does not change enzymatic activity but leads to proteasomal degradation (By similarity). Phosphorylated upon insulin stimulation; which may lead to enzyme activation. DISRUPTION PHENOTYPE: Chronic renal failure and kidney lesions. Affects podocyte morphology and function. SIMILARITY: Belongs to the PI3/PI4-kinase family. SIMILARITY: Contains 1 C2 domain. SIMILARITY: Contains 1 C2 PI3K-type domain. SIMILARITY: Contains 1 PI3K-RBD domain. SIMILARITY: Contains 1 PI3K/PI4K domain. SIMILARITY: Contains 1 PIK helical domain. SIMILARITY: Contains 1 PX (phox homology) domain. SEQUENCE CAUTION: Sequence=AAB07682.1; Type=Erroneous initiation; GENE SYNONYMS:Pik3c2a Cpk. COPYRIGHT: Protein annotation is derived from the UniProt Consortium (http://www.uniprot.org/).
