Anti-Akd2 antibodies enable researchers to detect and measure the Akd2 antigen in biological samples. This target is a reported synonym of the AK9 gene, which encodes adenylate kinase 9. This protein is known to function in protein phosphorylation, among other biological roles. The human version of Akd2 has a canonical amino acid length of 1911 residues and a protein mass of 221.4 kilodaltons, although 6 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Akd2 is a member of the Adenylate kinase protein family.
