Anti-MARCHF4 antibodies are used in the immunodetection of the protein membrane associated ring-CH-type finger 4. In humans, the canonical protein has a reported length of 410 amino acid residues and a mass of 45.5 kDa. Its subcellular localization is in the Golgi. It is reported to be expressed in the brain and placenta. MARCHF4 is known to be involved with protein ubiquitination. Synonyms for this target antigen include E3 ubiquitin-protein ligase MARCH4, RING finger protein 174, RING-type E3 ubiquitin transferase MARCH4, RING-type E3 ubiquitin transferase MARCHF4, and E3 ubiquitin-protein ligase MARCHF4. MARCHF4 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species.
