PI(4,5)P2 diC16

Phosphatidylinositol 4,5-bisphosphate diC16 (PI(4,5)P2 diC16) is a synthetic, purified dipalmitoyl PI(4,5)P2.

Phosphoinositides (PIP_ns) 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: Dipalmitoyl Phosphatidylinositol 4,5-bisphosphate, PtdIns(4,5)P2 (16:0/16:0), PI(4,5)P2 C16, or PIP2
