Itpkb Gene Summary [Rat]
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 several cellular components, including cytoskeleton; cytosol; and endoplasmic reticulum. Predicted to be active in cytoplasm and nucleus. Orthologous to human ITPKB (inositol-trisphosphate 3-kinase B). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Itpkb often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
