General annotation (Comments)

Function	3-phosphorylates the cellular phosphoinositide PtdIns-4,5-biphosphate (PtdIns(4,5)P2) to produce PtdIns-3, 4,5-triiphosphate (PtdIns(3,4,5)P3). Links G-protein coupled receptor activation to the secondary messenger PtdIns(3,4,5)P3 production.
Catalytic activity	ATP + 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate = ADP + 1-phosphatidyl-1D-myo-inositol 3,4,5-trisphosphate.
Enzyme regulation	Activated by both the alpha and the beta-gamma G proteins. Wortmannin sensitive in nM range. Ref.1
Pathway	Phospholipid metabolism; phosphatidylinositol phosphate biosynthesis.
Subunit structure	Heterodimer of a catalytic subunit (PIK3CG/p120) and a regulatory (PIK3R5a/p101) subunit By similarity.
Sequence similarities	Belongs to the PI3/PI4-kinase family. Contains 1 PI3K/PI4K domain.
