Anti-MARCHF9 antibodies are used in the immunodetection of the protein membrane associated ring-CH-type finger 9. In humans, the canonical protein has a reported length of 346 amino acid residues and a mass of 37.8 kDa. Its subcellular localization is in the Golgi and lysosomes. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. MARCHF9 is known to be involved with protein ubiquitination. Synonyms for this target antigen include E3 ubiquitin-protein ligase MARCH9, RING finger protein 179, RING-type E3 ubiquitin transferase MARCH9, RING-type E3 ubiquitin transferase MARCHF9, and E3 ubiquitin-protein ligase MARCHF9. MARCHF9 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species.
