Anti-OCA2 antibodies are used in the immunodetection of the protein OCA2 melanosomal transmembrane protein. In humans, the canonical protein has a reported length of 838 amino acid residues and a mass of 92.9 kDa. Its subcellular localization is in the membrane. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in melanocytes and retinal pigment epithelium. A member of the CitM (TC 2.A.11) transporter protein family, OCA2 is known to be involved with cell proliferation and melanocyte differentiation. Post-translational modifications have been described, including glycosylation. The OCA2 gene has been associated with the disease, Albinism. Synonyms for this target antigen include BEY1, BEY2, BOCA, D15S12, EYCL, EYCL2, EYCL3, and BEY. OCA2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some OCA2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
