Anti-RFX5 antibodies are used in the immunodetection of the protein regulatory factor X5. In humans, the canonical protein has a reported length of 616 amino acid residues and a mass of 65.3 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the RFX protein family, RFX5 is known to be involved with the regulation of transcription. Post-translational modifications have been described, including phosphorylation. The RFX5 gene has been associated with the disease, Bare lymphocyte syndrome. Synonyms for this target antigen include DNA-binding protein RFX5 and regulatory factor X, 5 (influences HLA class II expression). RFX5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of RFX5 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.
