Anti-MARCHF3 antibodies are used in the immunodetection of the protein membrane associated ring-CH-type finger 3. In humans, the canonical protein has a reported length of 253 amino acid residues and a mass of 28.5 kDa. Its subcellular localization is in the cytoplasmic vesicles. Up to 2 different isoforms have been reported for this protein. MARCHF3 is known to be involved with endocytosis and protein ubiquitination. Synonyms for this target antigen include E3 ubiquitin-protein ligase MARCH3, RING finger protein 173, RING-type E3 ubiquitin transferase MARCH3, RING-type E3 ubiquitin transferase MARCHF3, and E3 ubiquitin-protein ligase MARCHF3. MARCHF3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species.
