Regulator gene


noun, plural: regulator 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.


For instance, a regulator gene codes for repressor protein that binds to operator gene, which consequently prevents production of a particular enzyme. When that enzyme is needed again, a specific regulatory metabolite inhibits the repressor so that the enzyme is produced.

Also called: regulator, regulatory gene.

See also: gene regulation.

Cell transformation

Well with epigenetics, you could program the chromatin to 'silence' the genes required for the animal characteristics that you want. It could then be unsilenced with a specific regulator (such as a hormone, or another protein, or even miRNA?) and begin producing the gene ...

growth inhibitor gene

You ask if there is one gene to control size, I'm going to say that there are many many genes, all regulated ... The reason I am suggesting growth hormones is because the hormone itself is a regulator for many of those genes.
