Product Overview
This rabbit polyclonal antibody targets inositol-tetrakisphosphate 1-kinase (gene ITPK1) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 45.6 kDa, and the supplier reports an observed band at about 42 kDa.
Inositol-tetrakisphosphate 1-kinase (ITPK1) is a multifunctional inositol phosphate kinase. It phosphorylates Ins(1,3,4)P3 and Ins(3,4,5,6)P4 and can also act as a phosphatase, and it is a key enzyme for producing higher inositol phosphates such as InsP5 and InsP6.
