  • Ins(2,3,4,5)-P4 (ammonium salt)
  • 2,3,4,5-IP4 (ammonium salt)

D-myo-Inositol-2,3,4,5-tetraphosphate (Ins(2,3,4,5)-P4) is a member of the inositol phosphate (InsP) family of molecules that play a critical role as small, soluble second messengers in the transmission of cellular signals.1,2 The most studied InsP, Ins(1,4,5)-P3, more commonly referred to as IP3, is a second messenger produced in cells by phospholipase C (PLC)-mediated hydrolysis of phosphatidyl inositol-4,5-biphosphate.3,4 Binding of Ins(1,4,5)-P3 to its receptor on the endoplasmic reticulum results in opening of the calcium channels and an increase in intracellular calcium.4,5
