regulatory region

although classically defined in terms of the presence of mutations that affect regulation of gene expression, this is now considered to be the region of a gene where RNA Polymerase and other accessory transcription modulator Proteins bind and interact to control RNA synthesis. Although the promoter is an integral part of the regulatory region, this region may also contain binding sites for Proteins that function in either a positive or a negative modulating fashion and various nucleotide sequence features, such as attenuators, may contribute to regulation of transcription.
