Phosphatidylinositol 4-phosphate 3-kinase C2 domain-containing subunit alpha (PIK3C2A)

Generates phosphatidylinositol 3-phosphate (PtdIns3P) and phosphatidylinositol 3,4-bisphosphate (PtdIns(3,4)P2) that act as instant messengers. Has a role in many intracellular trafficking events.

Functions in insulin signaling and secretion. Required for translocation of the glucose transporter SLC2A4/GLUT4 into the plasma membrane and glucose uptake in response to insulin- mediated RHOQ activation.
