D-myo-Inositol-1,4,5-triphosphate trisodium (Inositol 1,4,5-trisphosphate trisodium) is a second messenger produced in cells by the phospholipase C-mediated hydrolysis of phosphatidylinositol-4,5-bisphosphate. It binds to Ins(1,4,5)P3 receptors, resulting in the opening of calcium channels and an increase in intracellular calcium.
