CC -!- FUNCTION: Phosphoinositide-3-kinase (PI3K) phosphorylates
CC phosphatidylinositol (PI) and its phosphorylated derivatives at
CC position 3 of the inositol ring to produce 3-phosphoinositides
CC (PubMed:1322797, PubMed:14729945). Uses ATP and PtdIns(4,5)P2
CC (phosphatidylinositol 4,5-bisphosphate) to generate
CC phosphatidylinositol 3,4,5-trisphosphate (PIP3) (By similarity). PIP3
CC plays a key role by recruiting PH domain-containing proteins to the
CC membrane, including AKT1 and PDPK1, activating signaling cascades
CC involved in cell growth, survival, proliferation, motility and
CC morphology. Participates in cellular signaling in response to various
CC growth factors. Involved in the activation of AKT1 upon stimulation by
CC receptor tyrosine kinases ligands such as EGF, insulin, IGF1, VEGFA and
CC PDGF. Involved in signaling via insulin-receptor substrate (IRS)
CC proteins. Essential in endothelial cell migration during vascular
CC development through VEGFA signaling, possibly by regulating RhoA
CC activity. Required for lymphatic vasculature development, possibly by
CC binding to RAS and by activation by EGF and FGF2, but not by PDGF.
CC Regulates invadopodia formation through the PDPK1-AKT1 pathway.
CC Participates in cardiomyogenesis in embryonic stem cells through a AKT1
CC pathway. Participates in vasculogenesis in embryonic stem cells through
CC PDK1 and protein kinase C pathway (By similarity). In addition to its
CC lipid kinase activity, it displays a serine-protein kinase activity
CC that results in the autophosphorylation of the p85alpha regulatory
CC subunit as well as phosphorylation of other proteins such as 4EBP1, H-
CC Ras, the IL-3 beta c receptor and possibly others (PubMed:15178440,
CC PubMed:14729945). Plays a role in the positive regulation of
CC phagocytosis and pinocytosis (By similarity).
