Predicted to enable inositol hexakisphosphate kinase activity and inositol-1,4,5-trisphosphate 3-kinase activity. Predicted to be involved in cellular response to calcium ion; inositol phosphate metabolic process; and phosphatidylinositol phosphate biosynthetic process. Predicted to act upstream of or within several processes, including common myeloid progenitor cell proliferation; negative regulation of neutrophil apoptotic process; and regulation of hemopoiesis. Predicted to be located in cytosol and membrane. Predicted to be active in cytoplasm and nucleus. Orthologous to human ITPKB (inositol-trisphosphate 3-kinase B).
