Trans-regulatory element
Trans-regulatory elements are genes which may modify (or regulate) the expression of distant genes.[1] More specifically, trans-regulatory elements are DNA sequences that encode transcription factors.
Trans-regulatory elements work through an intermolecular interaction between two different molecules: (1) a transcribed and translated transcription factor protein derived from the trans-regulatory element and a (2) DNA regulatory element that is adjacent to the regulated gene. This is in contrast to cis-regulatory elements that work through an intramolecular interaction between different parts of the same molecule: (1) a gene and (2) an adjacent regulatory element for that gene in the same DNA molecule.
