Anti-regulatory factor X7 antibodies are used for the immunodetection of the protein encoded by the RFX7 gene. In humans, the canonical protein has a reported length of 1363 amino acid residues and a mass of 146.9 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of the RFX protein family, it is known to be involved with the regulation of transcription. Other names for this target antigen include regulatory factor X domain containing 2, regulatory factor X domain-containing protein 2, and DNA-binding protein RFX7. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of regulatory factor X7 antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
