Regulatory gene. Definition. noun, plural: regulatory genes. A gene that is involved in the production of a substance that controls or regulates the expression of one or more genes, such as the gene that codes for a repressor protein that inhibits the activity of an operator gene.Supplement.he repressor protein binds to operator gene, which consequently prevents the production of a specific enzyme. When that enzyme is needed again, a specific regulatory metabolite inhibits the repressor so that the enzyme is produced. Also called: 1  regulator.
