WebChromatin signatures have allowed for the global mapping of enhancer cis-regulatory elements, however, the identification of silencer elements by computational or experimental approaches in a genome-wide manner are lacking. We present a simple but powerful computational approach to identify putative silencers genome-wide. WebJun 1, 2010 · Insulators prevent promiscuous gene regulation by restricting the action of enhancers and silencers. Recent studies have revealed a number of similarities between insulators and promoters, including binding of specific transcription factors, chromatin-modification signatures and localization to specific subnuclear positions.
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. Webenhancer blockers (when the insulator is located between a promoter and a cognate enhancer) and bar-riers (when located between a promoter and a silencer) [50]. Mutating or deleting insulators alters the pattern of gene expression and leads to developmental defects [51]. It has been suggested that insulators evolved from a class of promoters ...

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). dj j rob
