In the field of molecular biology, a corepressor is a substance that inhibits the expression of genes. A corepressor downregulates (or represses) the expression of genes not through direct interaction with a gene promoter (a sequence of DNA adjacent to the regulated gene), but rather indirectly through interaction with repressor proteins that in turn bind to the promoter.
