Anti-RNF111 antibodies are used in the immunodetection of the protein ring finger protein 111. In humans, the canonical protein has a reported length of 994 amino acid residues and a mass of 108.9 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 4 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the Arkadia protein family, RNF111 is known to be involved with the regulation of transcription and protein ubiquitination. Synonyms for this target antigen include hRNF111, E3 ubiquitin-protein ligase Arkadia, Arkadia, RING-type E3 ubiquitin transferase Arkadia, and ARK. RNF111 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some RNF111 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
