Anti-cdN antibodies are protein reagents that detect specific antigens. The cdN antigen is another term for the human protein 5', 3'-nucleotidase, cytosolic, encoded by the NT5C gene. The protein is known to function in metabolic processes, among other biological roles. Canonically, it has an amino acid length of 201 residues and a mass of 23.4 kilodaltons. Its subcellular localization is in the cytoplasm and it is notably expressed in skeletal muscle, heart and pancreas. The cdN protein is a member of the 5'(3')-deoxyribonucleotidase protein family.
