WebFeb 28, 2024 · Properly organizing DNA within the nucleus is critical to ensure normal downstream nuclear functions. CTCF and cohesin act as major architectural proteins, working in concert to generate thousands of high-intensity chromatin loops. Due to their central role in loop formation, a massive research effort has been dedicated to … 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.
WebCohesin extrudes DNA into loops that are thought to lengthen until CTCF boundaries are encountered6–12. Little is known about whether loop extrusion is impeded by DNA-bound machines. Here we show that the minichromosome maintenance (MCM) complex is a barrier that restricts loop extrusion in G1 phase. Single-nucleus Hi-C ... WebIntroduction: Various activities in biological cells are affected by three-dimensional genome structure. The insulators play an important role in the organization of higher-order structure. CTCF is a representative of mammalian insulators, which can produce barriers to prevent the continuous extrusion of chromatin loop. As a multifunctional protein, CTCF has tens …

Animal genomes are folded into loops and topologically associating domains (TADs) by CTCF and loop-extruding cohesins, but the live dynamics of loop formation and stability remain … WebMar 22, 2016 · CTCF loops insulate enhancer-regulated stimulus response genes from housekeeping genes. To investigate whether CTCF loops are enriched for enhancers …
WebChIP-seq on CTCF-aberrant patient cells with a distal BCL11B enhancer confirmed binding of CTCF and cohesin to the remaining intervening CTCF motifs, despite the lower CTCF levels in these patients. 4C-seq further showed that in these patients, the TLX3 promoter forms secondary loops with these intervening CTCF sites.
