A regulatory sequence (also called regulatory region or ~ element) is a promoter, enhancer or other segment of DNA where regulatory proteins such as transcription factors bind preferentially. They control gene expression and thus protein expression.

Regulatory sequences can also be found on messenger RNA, but they are generally not as well studied as those in DNA.
