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. WebNov 20, 2014 · Transcriptional activation throughout the eukaryotic lineage has been tightly linked with disruption of nucleosome organization at promoters, enhancers, silencers, insulators and locus control regions due to transcription factor binding.
