Metabolite Identification
Common NameD-myo-Inositol 1,3,4,6-tetrakisphosphate
DescriptionD-myo-Inositol 1,3,4,6-tetrakisphosphate, also known as Ins(1,3,4,6)P4, belongs to the class of organic compounds known as inositol phosphates. Inositol phosphates are compounds containing a phosphate group attached to an inositol (or cyclohexanehexol) moiety. D-myo-Inositol 1,3,4,6-tetrakisphosphate is an extremely strong acidic compound (based on its pKa). D-myo-Inositol 1,3,4,6-tetrakisphosphate participates in a number of enzymatic reactions. In particular, D-myo-inositol 1,3,4,6-tetrakisphosphate can be converted into D-myo-inositol 1,3,4,5,6-pentakisphosphate through the action of the enzyme inositol polyphosphate multikinase. In addition, D-myo-inositol 1,3,4,6-tetrakisphosphate can be biosynthesized from inositol 1,3,4-trisphosphate; which is mediated by the enzyme inositol-tetrakisphosphate 1-kinase. In humans, D-myo-inositol 1,3,4,6-tetrakisphosphate is involved in inositol phosphate metabolism and is a substrate for the tyrosine-protein kinase BTK.

Enzymes

General function:
Involved in catalytic activity
Specific function:
Kinase that can phosphorylate various inositol polyphosphate such as Ins(3,4,5,6)P4 or Ins(1,3,4)P3. Phosphorylates Ins(3,4,5,6)P4 at position 1 to form Ins(1,3,4,5,6)P5. This reaction is thought to have regulatory importance, since Ins(3,4,5,6)P4 is an inhibitor of plasma membrane Ca(2+)-activated Cl(-) channels, while Ins(1,3,4,5,6)P5 is not. Also phosphorylates Ins(1,3,4)P3 on O-5 and O-6 to form Ins(1,3,4,6)P4, an essential molecule in the hexakisphosphate (InsP6) pathway. Also acts as an inositol polyphosphate phosphatase that dephosphorylate Ins(1,3,4,5)P4 and Ins(1,3,4,6)P4 to Ins(1,3,4)P3, and Ins(1,3,4,5,6)P5 to Ins(3,4,5,6)P4. May also act as an isomerase that interconverts the inositol tetrakisphosphate isomers Ins(1,3,4,5)P4 and Ins(1,3,4,6)P4 in the presence of ADP and magnesium. Probably acts as the rate-limiting enzyme of the InsP6 pathway. Modifies TNF-alpha-induced apoptosis by interfering with the activation of TNFRSF1A-associated death domain.
