WebAug 10, 2016 · The structure of promoters, including plant promoters, can be divided into two regions—core promoter and distal region comprising enhancers and silencers (Fig. 1 ). Both these regions contain cis elements, which proteins, known as trans factors may bind to (Klug and Cummings 2003; Peremarti et al. 2010; Porto et al. 2014 ). Fig. 1 WebAn insulated located between an enhancer and a promoter prevents the activation of that promoter. If the enhancer/silencer works on its target in a downstream manner, then an insulator located upstream of the enhancer/silencer has no effect (i.e. the insulator must be located between the enhancer/silencer and its target). texas small patio landscapingWebRegulatory regions in DNA: promoters, enhancers, silencers, and insulators.
