Anti-COG4 antibodies are used in the immunodetection of the protein component of oligomeric golgi complex 4. In humans, the canonical protein has a reported length of 785 amino acid residues and a mass of 89.1 kDa. Its subcellular localization is in the membrane, Golgi, and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the COG4 protein family, COG4 is reported to be required for normal Golgi function. The COG4 gene has been associated with the disease, Congenital disorder of glycosylation. Synonyms for this target antigen include COD1, conserved oligomeric Golgi complex subunit 4, COG complex subunit 4, complexed with Dor1p, and CDG2J. COG4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some COG4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
