Inositol phosphates are important signaling molecules involved in numerous cellular functions. Inositol 1,3,4,6-tetrakissphosphate (Ins(1,3,4,6)P4) is an intermediate in the synthesis of InsP6 (phytic acid), being phosphorylated by Ins(1,3,4,6)P4 5-kinase to Ins(1,3,4,5,6)P5. It is formed from Ins(1,3,4)P3 by Ins(1,3,4)P3 5,6-kinase. |
