Anti-Ceruloplasmin antibodies are used for the immunodetection of the protein encoded by the CP gene. In humans, the canonical protein has a reported length of 1065 amino acid residues and a mass of 122.2 kDa. It is known to be a secreted protein. It is notably expressed by the liver and secreted in plasma. A member of the Multicopper oxidase protein family, it is known to be involved with the transport of ions. Post-translational modifications have been described, including glycosylation. The gene encoding this protein is implicated in Aceruloplasminemia. Other names for this target antigen include CP-2, ceruloplasmin (ferroxidase), and AB073614. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
