ITPK1 Antibody

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 tetraphosphate 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.

This ITPK1 antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 28-54 amino acids from the N-terminal region of human ITPK1.

Store at 4˚ C for three months and -20˚ C, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.
