Anti-Surfeit 4 antibodies are used for the immunodetection of the protein encoded by the SURF4 gene. In humans, the canonical protein has a reported length of 269 amino acid residues and a mass of 30.4 kDa. Its subcellular localization is in the ER and Golgi. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of the SURF4 protein family, it is known to be involved with Golgi organization and the metabolism of lipids. Other names for this target antigen include surfeit locus protein 4, surface 4 integral membrane protein, and ERV29. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some Surfeit 4 antibodies may have been used in research and have associated citations. Western Blot and Immunohistochemistry are common applications for these antibodies.
