Anti-chromatin accessibility complex subunit 1 antibodies are used for the immunodetection of the protein encoded by the CHRAC1 gene. In humans, the canonical protein has a reported length of 131 amino acid residues and a mass of 14.7 kDa. Its subcellular localization is in the nucleus. It is found to be expressed in the heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. It is noted to be involved in chromatin remodeling and DNA replication. Other names for this target antigen include CHARC15, CHRAC-15, CHRAC15, YCL1, chromatin accessibility complex protein 1, and CHARC1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
