| Background Information | PI3 Kinase (Phosphatidylinositol 3-Kinase) is responsible for phosphorylation of the 3 position of the inositol ring of PI(4,5)P2, to generate PI(3,4,5)P3, a potent second messenger required for survival, signaling, and insulin action. PI3 Kinase is a heterodimeric complex composed of an 85 kDa regulatory subunit and a 110 kDa catalytic subunit. Tyrosine phosphorylation of growth factor receptors creates docking sites for binding of p85 (through its SH2 domains) on the receptors; p85 brings with it p110, which is then proximal to its phospho-lipid substrate on the membrane. PI3 Kinase is also activated by Ras, and by the β:γ subunits of heterotrimeric g-proteins. PI3 Kinase is inhibitable by wortmannin, a useful tool for the study of the PI3 Kinase signaling pathway. |

| UniProt Summary | FUNCTION: Phosphorylates PtdIns, PtdIns4P and PtdIns(4,5)P2 with a preference for PtdIns(4,5)P2. CATALYTIC ACTIVITY: ATP + 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate = ADP + 1-phosphatidyl-1D-myo-inositol 3,4,5-trisphosphate. SUBUNIT STRUCTURE: Heterodimer of a p110 (catalytic) and a p85 (regulatory) subunit. Binds to IRS1 in nuclear extracts. Interacts with RUFY3 By similarity. INVOLVEMENT IN DISEASE: Defects in PIK3CA are associated with colorectal cancer (CRC) [MIM:114500]. Defects in PIK3CA are associated with breast cancer [MIM:114480]. Defects in PIK3CA are associated with epithelial ovarian cancer (EOC) [MIM:604370]. Defects in PIK3CA may underlie hepatocellular carcinoma (HCC) [MIM:114550]. Ref.14 PI3KCA mutations affecting exons 9 and 20 display gender- and tissue-specific patterns, thus suggesting that the different amino acid changes could exert distinct functional effects on the oncogenic properties of this enzyme. Furthermore, sexual dimorphisms and tissue specific factors might directly or indirectly influence the occurrence of PI3KCA cancer alleles. SEQUENCE SIMILARITIES: Belongs to the PI3/PI4-kinase family. Contains 1 C2 domain. Contains 1 PI3K/PI4K domain. |
