Ctcf cohesion
WebIn CTCF-depleted cells, most of the cohesin-bound sites are unperturbed, indicating overlapping as well as distinct functions of CTCF and cohesin in genome organization [36,60,61]. Interestingly, cohesin copurifies and colocalizes with mediator complex, which is recruited mostly to activate gene promoters and enhancers [62,63] . WebCTCF and cohesin have also been recently correlated with both interaction frequency and gene expression during differentiation (12), indicating that they may play major roles in mediating the impacts of chromatin structure on gene regulation. However, the exact mechanisms these factors use to contribute
