The PI3Ks are divided into three classes: I, II and III, and only the class I PI3Ks are involved in oncogenesis. This gene encodes the 101 kD regulatory subunit of the class I PI3K gamma complex, which is a dimeric enzyme, consisting of a 110 kD catalytic subunit gamma and a regulatory subunit of either 55, 87 or 101 kD. This protein recruits the catalytic subunit from the cytosol to the plasma membrane through high-affinity interaction with G-beta-gamma proteins. Multiple alternatively spliced transcript variants encoding two distinct isoforms have been found. [provided by RefSeq, Oct 2011]. * **UniProt Summary**: Regulatory subunit of the PI3K gamma complex. Required for recruitment of the catalytic subunit to the plasma membrane via interaction with beta-gamma G protein dimers. Required for G protein-mediated activation of PIK3CG (By similarity). {ECO:0000250}. |PI3K 1B p101| |phosphatidylinositol 3-kinase complex, class IB| |1-phosphatidylinositol-3-kinase regulator activity| |phosphatidylinositol 3-kinase complex| |G-protein beta/gamma-subunit complex binding| |phosphatidylinositol 3-kinase signaling| |regulation of phosphatidylinositol 3-kinase activity| |regulation of lipid kinase activity| |phosphatidylinositol-mediated signaling| |inositol lipid-mediated signaling| |regulation of phospholipid metabolic process| |positive regulation of phosphatidylinositol 3-kinase signaling| |phosphatidylinositol biosynthetic process| |regulation of phosphatidylinositol 3-kinase signaling| |platelet activation| |microtubule organizing center| |positive regulation of protein kinase B signaling| |phosphatidylinositol metabolic process| |glycerophospholipid biosynthetic process| |regulation of protein kinase B signaling| |glycerolipid biosynthetic process| |phospholipid biosynthetic process| |positive regulation of MAP kinase activity| |blood coagulation| |coagulation| |hemostasis| |glycerophospholipid metabolic process| |positive regulation of protein serine/threonine kinase activity| |regulation of MAP kinase activity| |phospholipid metabolic process| |glycerolipid metabolic process| |regulation of lipid metabolic process| |wound healing| |regulation of body fluid levels| |regulation of protein serine/threonine kinase activity| |positive regulation of protein kinase activity| |organophosphate biosynthetic process| |positive regulation of MAPK cascade| |response to wounding| |positive regulation of kinase activity| |lipid biosynthetic process| |positive regulation of transferase activity| |regulation of MAPK cascade| |regulation of protein kinase activity| |regulation of kinase activity| |organophosphate metabolic process| |cellular lipid metabolic process| |regulation of transferase activity| |positive regulation of protein phosphorylation| |positive regulation of intracellular signal transduction| |positive regulation of phosphorylation| |cell activation| |positive regulation of phosphorus metabolic process| |positive regulation of phosphate metabolic process| |lipid metabolic process| |positive regulation of protein modification process| |G protein-coupled receptor signaling pathway| |positive regulation of catalytic activity| |regulation of protein phosphorylation| |regulation of phosphorylation| |positive regulation of cellular protein metabolic process| |positive regulation of signal transduction| |intracellular signal transduction| |positive regulation of protein metabolic process| |positive regulation of molecular function| |regulation of phosphate metabolic process| |regulation of phosphorus metabolic process| |positive regulation of cell communication| |positive regulation of signaling| |regulation of intracellular signal transduction| |regulation of protein modification process| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp441|GSK-J4 1.5μM R08 exp441]]|-1.72| |[[:results:exp347|Cyclosporin-A 0.8μM R07 exp347]]|2.19| No correlation found to any other genes in chemogenomics.
