Metabolite Identification
Common NameD-myo-Inositol 3,4,5,6-tetrakisphosphate
DescriptionInositol phosphates are a family of water-soluble intracellular signalling molecules derived from membrane inositol phospholipids. They undergo a variety of complex interconversion pathways, and their levels are dynamically regulated within the cytosol in response to a variety of agonists. D-myo-Inositol 3,4,5,6-tetrakisphosphate, also known as Ins(3,4,5,6)P4, has a direct biphasic (activation/inhibition) effect on an epithelial Ca2+-activated chloride channel. The effect of Ins(3,4,5,6)P4 is not mimicked by other inositol tetrakisphosphate isomers, is dependent on the prevailing calcium concentration, and is influenced when channels are phosphorylated by calmodulin kinase II. The predominant effect of Ins(3,4,5,6)P4 on phosphorylated channels is inhibitory at levels of intracellular calcium observed in stimulated cells. Ins(3,4,5,6)P4 activity acts to inhibit calcium-dependent chloride secretion. The secretion of fluid and electrolytes across intestinal epithelial cells in response to Ca2+-dependent secretagogues is a tightly regulated process that is subject to both positive and negative influences. Agonists of Gq protein-coupled receptor (GqPCRs) appear to have the ability to evoke antisecretory mechanisms. One is mediated by the generation of Ins(3,4,5,6)P4 and serves to chronically downregulate epithelial responsiveness to subsequent challenges with Ca2+-dependent agonists (PMID: 12388102 , 11408264 ).

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.
