Anti-RNF38 antibodies are used in the immunodetection of the protein ring finger protein 38. In humans, the canonical protein has a reported length of 515 amino acid residues and a mass of 57.6 kDa. Its subcellular localization is in the nucleus. Up to 5 different isoforms have been reported for this protein. It is reported to be widely expressed with highest levels in testis. RNF38 is known to act as a E3 ubiquitin-protein ligase able to ubiquitinate p53/TP53 which promotes its relocalization to discrete foci associated with PML nuclear bodies. Synonyms for this target antigen include E3 ubiquitin-protein ligase RNF38 and RING-type E3 ubiquitin transferase RNF38. RNF38 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of RNF38 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
