Insulator transcription

Insulators contain clustered binding sites for sequence specific DNA-binding proteins and mediate intra- and inter-chromosomal interactions. Insulators function either as an enhancer-blocker or a barrier, or both. The mechanisms by which an insulator performs these two functions include loop formation … Se mer An insulator is a type of cis-regulatory element known as a long-range regulatory element. Found in multicellular eukaryotes and working over distances from the promoter element of the target gene, an insulator is typically 300 Se mer Insulators have two main functions: 1. Enhancer-blocking insulators prevent distal enhancers from acting on the promoter of … Se mer The CTCF insulator appears to have enhancer blocking activity via its 3D structure and have no direct connection with barrier activity.
