Anti-INSP6K3 antibodies enable researchers to detect and measure the INSP6K3 antigen in biological samples. This target is a reported synonym of the IP6K3 gene, which encodes inositol hexakisphosphate kinase 3. This protein is known to function in protein phosphorylation, among other biological roles. The human version of INSP6K3 has a canonical amino acid length of 410 residues and a protein mass of 46.4 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in the heart muscle and skeletal muscle. INSP6K3 is a member of the Inositol phosphokinase (IPK) protein family.
