(Redirected from Corepressor (genetics)) In the field of molecular biology, a corepressor is a substance that inhibits the expression of genes. In prokaryotes, corepressors are small molecules whereas in eukaryotes, corepressors are proteins. A corepressor does not directly bind to DNA, but instead indirectly regulates gene expression by binding to repressors.
Term. repressor. Definition. tetrameric protein which controls the lac operator, it is bound to operator when lactose is not present. When lactose is present, it binds to the repressor, which causes it to dissociate from the operator.Term. lactose. Definition. sugar present in milk, a low levels repressor it bound to operator, a high levels it binds to repressor allowing for dissociation and gene transcription.ses energy from ATP to help unwind the DNA at the start site allowing Pol II to form an open complex in which DNA around the start site is melted and the template strand id bound at the polymerase active site.
