WebJan 14, 2024 · Here, we sought to clarify the relationship between CTCF and cohesin during formation of chromatin loops. First, we show that more than 95% of CTCF sites are also bound by cohesin in multiple cell lines, implying a nearly universal role of CTCF in the retention of cohesin onto chromatin independent of the sequence or function of the … WebCTCF is a nuclear protein initially discovered for its role in enhancer-promoter insulation. It has been shown to play a role in genome architecture and in fact, its DNA binding sites …
WebSummary. CTCF (CCCTC-binding factor) is a highly conserved 11-zinc finger DNA binding protein with tens of thousands of binding sites genome-wide. CTCF acts as a multifunctional regulator of transcription, having been previously associated with activator, repressor, and insulator activity. These diverse regulatory functions are crucial for ... WebMar 16, 2024 · Group 1 showed the highest enrichment for CTCF binding sites at both anchors (Fig. (Fig.4b, 4 b, upper panel), suggesting that disruption of the CTCF binding by genetic variants at the SNP anchor may also affect the loop structure, and thus, the binding activities at the non-SNP anchor in spatial proximity.
