Phosphatidylinositol 4-phosphate diC8 (PI(4)P diC8) (ammonium salt) is a synthetic, purified dioctanoyl PI(4)P. Phosphoinositides (PIPns) are minor components of cellular membranes but are integral signaling molecules for cellular communication. Phosphatidylinositol 4-phosphate is the biosynthetic precursor to PI(4,5)P2 and has an important roles in regulating sphingomyelin and glycosphingolipid metabolism and membrane trafficking at the exit of the Golgi complex. |
