Phosphatidylinositol 4,5-bisphosphate diC4 (PI(4,5)P2 diC4) is a synthetic, purified dibutanoyl PI(4,5)P2.
Phosphoinositides (PIPns) are minor components of cellular membranes but are integral signaling molecules for cellular communication. Phosphatidylinositol 4,5-bisphosphate (PIP2) has been shown to play a central role in a variety of cellular functions. Amongst its many functions, PIP2 is a substrate for Phospholipase C-coupled G-protein pathways involved in intracellular calcium release in a number of tissues and is also a substrate for class I phosphoinositide 3-kinase (PI3-K).
Alternate Names: D-myo-Phosphatidylinositol 4,5-bisphosphate, Dibutanoyl Phosphatidylinositol 4,5-bisphosphate, PtdIns(4,5)P2 C4, PI(4,5)P2 C4, or (4:0/4:0) PIP2
