WebPI (4,5)P2 is also a substrate for PI 3-kinase where it is phosphorylated to PI (3,4,5)P3, an activator of downstream signaling components such as the protein kinase AKT. Phosphatidylinositol 4,5-bisphosphate (PIP2) is a negatively charged phospholipid, abundant in the plasma membrane. 1 Application WebThe lipid phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P 2 or PIP 2) plays many roles in the plasma membrane of mammalian cells. For example, it is the source of three different second messengers. It also acts as a regulator or second messenger itself when it acti-vates scores of ion channels, mediates both endocytosis and exocy-

Phosphorylated forms of phosphatidylinositol (PI) are called phosphoinositides and play important roles in lipid signaling, cell signaling and membrane trafficking. The inositol ring can be phosphorylated by a variety of kinases on the three, four and five hydroxyl groups in seven different combinations. However, the two and six hydroxyl groups are typically not phosphorylated due to steric hindrance.
