1-Phosphatidyl-D-myo-inositol 4,5-bisphosphate

Phosphatidylinositol 4,5-Diphosphate A phosphoinositide present in all eukaryotic cells, particularly in the plasma membrane. It is the major substrate for receptor-stimulated phosphoinositidase C, with the consequent formation of inositol 1,4,5-triphosphate and diacylglycerol, and probably also for receptor-stimulated inositol phospholipid 3-kinase.
