apo·re·pres·sor (ap″o-re-presґər) an inactive form of a repressor (q.v.), requiring binding of a corepressor to become a functional repressor.Medical dictionary. 2011.
Aporepressor — In molecular biology, an aporepressor is a regulator protein that acts on an operon. Its activity is modulated by small molecules, such as metabolites, called corepressors. It is activated when its corepressor binds, at which point it binds at… … Wikipedia

corepressor — A molecule, usually a product of a specific metabolic pathway, that combines with and activates a repressor produced by a regulator gene. The activated repressor then attaches to an operator gene site and … Medical dictionary
Corepressor — In molecular genetics, 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… … Wikipedia
