Medical Term:
corepressor
Pronunciation: kō′rē-pres′ŏr
Definition: A molecule, usually a product of a specific metabolic pathway (nuclear protein), which combines with and activates a repressor produced by a regulator gene. The activated repressor then attaches to an operator gene site and inhibits activity of the structural genes. This homeostatic mechanism negatively regulates enzyme production in repressible enzyme systems.
