Anti-NCOA1 antibodies are used in the immunodetection of the protein nuclear receptor coactivator 1. In humans, the canonical protein has a reported length of 1441 amino acid residues and a mass of 156.8 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the SRC/p160 nuclear receptor coactivator protein family, NCOA1 is known to be involved with the regulation of apoptosis and the regulation of transcription. Synonyms for this target antigen include KAT13A, RIP160, SRC1, bHLHe42, bHLHe74, Hin-2 protein, class E basic helix-loop-helix protein 74, and F-SRC-1. NCOA1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 90 citations in the literature describe the use of NCOA1 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
