PIP2
(Phosphatidylinositol 4,5-biphosphate)
#
Since having one phosphate is intrinsic to regular PI (look at the acronyms.), it literally has 3 phosphates, and PIP3 has 4. Usually Stearic Acid in 1 and Arachidonic Acid in 2.
- PI3K phosphorylates it into PIP3.
- Phospholipase C cleaves it into Inositol Triphosphate + Diacylglycerol.
