Anti-RNF31 antibodies are used in the immunodetection of the protein ring finger protein 31. In humans, the canonical protein has a reported length of 1072 amino acid residues and a mass of 119.7 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in both normal and transformed breast epithelial cell lines. A member of the RBR protein family, RNF31 is known to be involved with NF-kappaB signaling pathways and protein ubiquitination. Post-translational modifications have been described, including ubiquitination and protein cleavage. Synonyms for this target antigen include Paul, ZIBRA, E3 ubiquitin-protein ligase RNF31, HOIL-1-interacting protein, RING-type E3 ubiquitin transferase RNF31, and HOIP. RNF31 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of RNF31 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunofluorescence is also a common application.
