WebPhosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit gamma isoform is an enzyme that in humans is encoded by the PIK3CG gene . Function [ edit] This gene encodes a protein that belongs to the pi3/pi4-kinase family of proteins. WebIdelalisib, a PI3K small molecule inhibitor, specifically blocks the phosphatidylinositol-4, 5-bisphosphate 3-kinase catalytic subunit delta isoform (PI3Kδ). This drug is targeted specifically for relapsed chronic lymphocytic leukemia (CLL). The pathogenesis for CLL is through the B cell receptor and the PI3K pathway normally regulates this.

Phosphatidylinositol 4,5-bisphosphate or PtdIns(4,5)P2, also known simply as PIP2 or PI(4,5)P2, is a minor phospholipid component of cell membranes. PtdIns(4,5)P2 is enriched at the plasma membrane where it is a substrate for a number of important signaling proteins. PIP2 also forms lipid clusters that sort … See more PIP2 is a part of many cellular signaling pathways, including PIP2 cycle, PI3K signalling, and PI5P metabolism. Recently, it has been found in the nucleus with unknown function.
