Anti-CENPX antibodies are used in the immunodetection of the protein centromere protein X. In humans, the canonical protein has a reported length of 81 amino acid residues and a mass of 9 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. A member of the CENP-X/MHF2 protein family, CENPX is reported to be a DNA-binding component of the Fanconi anemia (FA) core complex. Synonyms for this target antigen include FANCM-interacting histone fold protein 2, Fanconi anemia-associated polypeptide of 10 kDa, retinoic acid-inducible gene D9 protein homolog, and FANCM associated histone fold protein 2. CENPX gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These CENPX antibodies are widely used in Western Blot experiments, among other applications.
