Cis-acting element definition
WebOct 2, 2024 · An enhancer is a cis-acting element involved in increasing the activity of a particular promoter. It is a short DNA sequence of about 50-1500 bp and the transcription factors called activators can bind to it. The location of the enhancer can be up to 1 Mbp away from the promoter. It also can be upstream or downstream to the promoter. WebApr 20, 2024 · Both cis-acting and trans-acting factors have the potential to regulate gene expression patterns in the brain and to mediate the interaction between environment and gene expression.

WebPromoter or cis -regulatory element is a region of DNA at which transcription of particular gene initiates. Generally, promoter consists of three regions—core, proximal, and distal regions. Core region contains transcription start site and binding site for RNA polymerase and it is required for proper initiation of transcription.
