PI3K is composed of a catalytic and a regulatory subunit. The protein encoded by this gene represents a regulatory subunit of PI3K. The encoded protein contains two SH2 domains through which it binds activated protein tyrosine kinases to regulate their activity. [provided by RefSeq, Jun 2016]. * **UniProt Summary**: Binds to activated (phosphorylated) protein-tyrosine kinases through its SH2 domain and regulates their kinase activity. During insulin stimulation, it also binds to IRS-1. |SH2| |1-phosphatidylinositol-3-kinase activity| |1-phosphatidylinositol-3-kinase regulator activity| |phosphatidylinositol-3-phosphate biosynthetic process| |phosphatidylinositol 3-kinase complex| |cell migration involved in sprouting angiogenesis| |blood vessel endothelial cell migration| |protein kinase B signaling| |phosphotyrosine residue binding| |phosphatidylinositol phosphorylation| |regulation of phosphatidylinositol 3-kinase activity| |sprouting angiogenesis| |regulation of lipid kinase activity| |lipid phosphorylation| |endothelial cell migration| |epithelial cell migration| |regulation of phospholipid metabolic process| |epithelium migration| |insulin receptor signaling pathway| |tissue migration| |phosphatidylinositol biosynthetic process| |cellular response to insulin stimulus| |phosphatidylinositol metabolic process| |ameboidal-type cell migration| |lipid modification| |glycerophospholipid biosynthetic process| |glycerolipid biosynthetic process| |response to insulin| |phospholipid biosynthetic process| |cellular response to peptide hormone stimulus| |glycerophospholipid metabolic process| |angiogenesis| |cellular response to peptide| |phospholipid metabolic process| |glycerolipid metabolic process| |response to peptide hormone| |regulation of lipid metabolic process| |blood vessel morphogenesis| |response to peptide| |blood vessel development| |positive regulation of cell migration| |transmembrane receptor protein tyrosine kinase signaling pathway| |vasculature development| |cardiovascular system development| |positive regulation of cell motility| |organophosphate biosynthetic process| |positive regulation of cellular component movement| |positive regulation of locomotion| |lipid biosynthetic process| |cellular response to organonitrogen compound| |cellular response to hormone stimulus| |tube morphogenesis| |cellular response to nitrogen compound| |enzyme linked receptor protein signaling pathway| |tube development| |regulation of cell migration| |circulatory system development| |regulation of kinase activity| |organophosphate metabolic process| |anatomical structure formation involved in morphogenesis| |response to hormone| |regulation of cell motility| |cellular lipid metabolic process| |cell migration| |regulation of transferase activity| |regulation of locomotion| |regulation of cellular component movement| |response to organonitrogen compound| |positive regulation of protein phosphorylation| |cellular response to oxygen-containing compound| |positive regulation of phosphorylation| |cell motility| |localization of cell| |response to nitrogen compound| |positive regulation of phosphate metabolic process| |positive regulation of phosphorus metabolic process| |lipid metabolic process| |cellular response to endogenous stimulus| |positive regulation of protein modification process| |phosphorylation| |locomotion| |regulation of protein phosphorylation| |response to endogenous stimulus| |movement of cell or subcellular component| |response to oxygen-containing compound| |regulation of phosphorylation| |positive regulation of cellular protein metabolic process| |intracellular signal transduction| |positive regulation of protein metabolic process| |regulation of phosphate metabolic process| |regulation of phosphorus metabolic process| |regulation of protein modification process| |positive regulation of gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp498|Lead acetate 2000μM R08 exp498 no dilution day6]]|-2.04| |[[:results:exp533|TNF-alpha 44ng/ml R08 exp533]]|-1.99| |[[:results:exp107|UMK57 0.6μM R03 exp107]]|1.75| |[[:results:exp16|DABN 2μM R00 exp16]]|1.83| |[[:results:exp132|Metformin 40μM R03 exp132]]|1.86| |[[:results:exp5|Alpha-Amanitin 0.5μM R00 exp5]]|1.91| |[[:results:exp103|Taxol 0.004μM R03 exp103]]|2.37| |[[:results:exp23|Nocodazole 0.02μM R00 exp23]]|2.42| No correlation found to any other genes in chemogenomics.
