Anti-NOPCHAP1 antibodies are used in the immunodetection of the protein NOP protein chaperone 1. In humans, the canonical protein has a reported length of 185 amino acid residues and a mass of 20.1 kDa. Its subcellular localization is in the nucleus. Synonyms for this target antigen include DNA damage-sensitive RNA 1 and uncharacterized protein C12orf45. NOPCHAP1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
