Phosphatidylinositol 5-phosphate diC8 (ammonium salt) is a synthetic, purified dioctanoyl PI(5)P.
Phosphoinositides (PIPns) are minor components of cellular membranes but are integral signaling molecules for cellular communication. Phosphatidylinositol 5-phosphate (PI(5)P) is a rare lipid found in the nucleus that can bind the PHD finger of the nuclear adapter protein ING2. PI(5)P is phosphorylated to PI(4,5)P2 by Type II PIP kinases.
