D-myo-Inositol-1,3,4,5-tetrakisphosphate, octapotassium salt is formed by phosphorylation of Ins(1,4,5)P3. Suggested to play a second-messenger role different from that of Ins(1,4,5)P3. D-myo-Inositol-1,3,4,5-tetrakisphosphate, octapotassium salt is a weak agonist of Ca2+ mobilizing receptors that is reported to mobilize intracellular Ca2+ stores in saponin-permeabilized SH-SY5Y neuroblastoma cells (EC50 = 2.05 muM).
