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. WebCTCF depletion leads to widespread upregulation of antisense transcription at divergent promoters. a, Schematic of the PRO-seq experiment (left) and quantification strategy (right).b, Schematic of the experimental set-up.c, PRO-seq MA plot of control versus CTCF-depleted cells on the antisense strand (−1,000 base pair (bp) to +200 bp relative to …

WebJul 2, 2024 · The ATAC-Seq peaks bound with or without CTCF/Cohesin in both promoters and distal elements showed no obvious differences (Additional file 1: Fig. S7a), indicating general chromatin compaction after 6 h of Pol II depletion. These results implicate that Pol II degradation may indirectly change the 3D chromatin interactions. WebTo study the regulatory mechanism, the Pax6 reporter and its deletion mutant activities were determined in transfected Rb cells and chicken embryonic retinas, revealing that CTCF interacts with the Pax6 gene in Rb cells through transcription control in the 5'-flanking region upstream from the Pax6 P0 promoter.
