The binding of CTCF has been shown to have many effects, which are enumerated below. In each case, it is unknown if CTCF directly evokes the outcome or if it does so indirectly (in particular through its looping role). The protein CTCF plays a heavy role in repressing the insulin-like growth factor 2 gene, by binding to the H-19 imprinting control region (ICR) along with differentially-methylated region-1 (DMR1) a… 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 ...

WebSep 28, 2024 · Remarkably, a C-terminally oriented CTCF accelerates DNA compaction by cohesin. DNA-bound Cas9 and Cas12a ribonucleoproteins are also polar cohesin barriers, indicating that stalling is intrinsic to cohesin itself, and other proteins can substitute for CTCF in fruit flies and other eukaryotes. Finally, we show that RNA-DNA hybrids (R-loops ... WebApr 14, 2024 · Abstract. 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 … WebDec 15, 2024 · It is shown that cohesin suppresses compartments but is required for TADs and loops, that CTCF defines their boundaries, and that the cohes in unloading factor WAPL and its PDS5 binding partners control the length of loops.
