Anti-RNF20 antibodies are used in the immunodetection of the protein ring finger protein 20. In humans, the canonical protein has a reported length of 975 amino acid residues and a mass of 113.7 kDa. Its subcellular localization is in the nucleus. It is reported to be expressed in the normal brain and also in malignant gliomas. A member of the BRE1 protein family, RNF20 is a known component of the RNF20/40 E3 ubiquitin-protein ligase complex that mediates monoubiquitination of 'Lys-120' of histone H2B (H2BK120ub1). Synonyms for this target antigen include BRE1 E3 ubiquitin ligase homolog, RING-type E3 ubiquitin transferase BRE1A, homolog of S. cerevisiae BRE1, and E3 ubiquitin-protein ligase BRE1A. RNF20 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of RNF20 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.
