Phosphoinositide-3-kinase (PI3K) phosphorylates phosphatidylinositol (PI) and its phosphorylated derivatives at position 3 of the inositol ring to produce 3-phosphoinositides (PubMed:15135396, PubMed:23936502, PubMed:28676499). Uses ATP and PtdIns(4,5)P2 (phosphatidylinositol 4,5-bisphosphate) to generate phosphatidylinositol 3,4,5-trisphosphate (PIP3) (PubMed:15135396, PubMed:28676499). PIP3 plays a key role by recruiting PH domain-containing proteins to the membrane, including AKT1 and PDPK1, activating signaling cascades involved in cell growth, survival, proliferation, motility and morphology. Participates in cellular signaling in response to various growth factors. Involved in the activation of AKT1 upon stimulation by receptor tyrosine kinases ligands such as EGF, insulin, IGF1, VEGFA and PDGF. Involved in signaling via insulin-receptor substrate (IRS) proteins. Essential in endothelial cell migration during vascular development through VEGFA signaling, possibly by regulating RhoA activity. Required for lymphatic vasculature development, possibly by binding to RAS and by activation by EGF and FGF2, but not by PDGF. Regulates invadopodia formation through the PDPK1-AKT1 pathway. Participates in cardiomyogenesis in embryonic stem cells through a AKT1 pathway. Participates in vasculogenesis in embryonic stem cells through PDK1 and protein kinase C pathway. In addition to its lipid kinase activity, it displays a serine-protein kinase activity that results in the autophosphorylation of the p85alpha regulatory subunit as well as phosphorylation of other proteins such as 4EBP1, H-Ras, the IL-3 beta c receptor and possibly others (PubMed:23936502, PubMed:28676499). Plays a role in the positive regulation of phagocytosis and pinocytosis (By similarity).

PI 3 kinase catalytic subunit alpha also known as PIK3CA or PI3K-alpha is a protein kinase with significant roles in cellular signaling. This protein has a mass of approximately 124 kDa and is part of the PI3 kinase family. PIK3CA is primarily expressed in various tissues including the liver breast and pancreas where it plays an important role in the regulation of cell growth and survival. The structure of PI3 kinase involves a complex of p110 catalytic subunits and p85 regulatory subunits which facilitate its enzymatic functions.
The PIK3CA protein phosphorylates the inositol ring of phosphoinositides generating phosphatidylinositol (345)-trisphosphate (PIP3) a lipid second messenger involved in numerous signaling pathways. PIK3CA often acts within a complex interacting with regulatory subunits such as p85 to control its activity. The complex formation enhances its stability and localization to the cell membrane where it can exert its enzymatic actions effectively. In its biological capacity PIK3CA plays a role in cellular proliferation survival and metabolism.
The PI3K/Akt signaling pathway involves PIK3CA as an important mediator. This pathway is integral to numerous cellular processes including metabolism growth and survival. PIK3CA links closely with Akt a downstream protein kinase that propagates the signal initiated by PIP3 generation. The mTOR pathway is another critical route involving PIK3CA where it regulates translation and cellular growth. These pathways emphasize the importance of PIK3CA in maintaining cellular homeostasis and responding to external growth signals.
Mutations and aberrations in PIK3CA associate with several cancers especially breast and colorectal cancers. The altered activity of PIK3CA can cause uncontrolled cell proliferation due to constant activation of the PI3K/Akt signaling pathway. This disrupts normal cellular apoptosis and fosters tumor growth. Additionally PIK3CA mutations are linked to certain genetic disorders such as PIK3CA-related overgrowth spectrum (PROS) where overactivation alters normal tissue growth and development. The interaction of PIK3CA with proteins like PTEN a tumor suppressor involved in cancer pathways also highlights its significance in oncogenic processes.
