WebHere we show that the minichromosome maintenance (MCM) complex is a barrier that restricts loop extrusion in G1 phase. Single-nucleus Hi-C (high-resolution chromosome conformation capture) of mouse zygotes reveals that MCM loading reduces CTCF-anchored loops and decreases TAD boundary insulation, which suggests that loop extrusion is … WebApr 5, 2024 · The regulatory functions of these co-factors in CTCF-mediated chromatin insulation and long-range chromatin interactions need to be further investigated in detail. Limitation of the study. As Ctcf is ubiquitously expressed in a manner similar to a housekeeping gene, and CTCF is essential for cell survival, it is therefore not possible to ...
