WebFeb 1, 2024 · Figure 2. Regulation of enhancer–promoter interaction by CTCF and cohesin. Cohesin is thought to progressively extrude chromatin loops until it encounters convergent CTCF sites. When CTCF sites are present at promoter-proximal ( a) or enhancer-proximal ( b) location, cohesin will drive asymmetric loop extrusion. WebJul 16, 2024 · One could speculate whether this relates to CTCF as an TF and an activator of gene expression at promoters and as an insulator located at more promoter-distant regions. 45 In line with this, depletion of CTCF has previously been shown to decrease gene expression near transcription start sites and induce gene expression more distal to ...
