Phosphatidylinositol (PI) is unusual among membrane lipids because it can undergo reversible phosphorylation at multiple sites on the inositol head to generate a variety of phosphorylated PI lipids called phosphoinositides. In a cell signaling event, the enzyme that directly converts PI(4, 5)P2 to PI(3, 4, 5)P3 is:
1
PI3-Kinase
2
PLCβ
