WebCore promoters combined with general transcription factors are sufficient to direct transcription initiation, but generally have low basal activity. Other important cis-regulatory modules are localized in DNA regions that are … WebThere are several types of gene regulatory elements, including promoters, enhancers, silencers, and insulators (Figure 1). Promoters are located near a gene’s transcription start site and are where the transcription machinery assembles (for an in-depth review of promoters, see 104, 110).

WebInsulators mark the boundaries of chromatin domains by limiting the range of action of enhancers and silencers. Although the properties of insulators have been well studied, … WebSilencers are regulatory DNA elements that reduce transcription from their target promoters; they are the repressive counterparts of enhancers. Although discovered decades ago, and despite evidence of their importance in development and disease, silencers have been much less studied than enhancers. Recently, however, a series of papers have reported …

WebAn enhancer is a DNA sequence that stimulates transcription a distance away from the promoter. A silencer is a DNA sequence with an inhibitory effect on the transcription of distant genes. An insulator is a DNA sequence that can serve as a barrier to protect a gene against the effects of an enhancer or silencer. All three are cis elements.
