"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 are enriched at the borders of chromatin domains. Recently, we showed that depletion of CTCF impairs the DNA damage response to ionizing radiation. To investigate the relationship … " - Ctcf binding sites

WebInstead, control of the access of CTCF to its cognate DNA binding sites appears to be regulated by two main types of chromatin modifications. First, CpG methylation prevents CTCF binding to DNA (Wang et al. 2012), as exemplified by methylation-controlled CTCF recruitment to the imprinted H19/Igf2 locus (Hark et al. 2000). Second, data shown ... WebAug 23, 2024 · Here, we propose a novel deep learning model, called CLNN-loop, to predict chromatin loops in different cell lines and CTCF-binding sites (CBS) pair types by fusing multiple sequence-based features. The analysis of a series of examinations based on the datasets in the previous study shows that CLNN-loop has satisfactory performance and is ...

WebCTCF deletions, frameshifts, or splice site mutations are almost exclusively found in those patients that preserve these intervening CTCF-binding sites in the breakpoint area. Only a few patients for whom we failed to identify CTCF aberrations had retained intervening CTCF motifs in between TLX3 and the distal BCL11B enhancer. WebJun 28, 2024 · Intragenic CTCF binding sites, particularly those proximal to splice junctions, influence pre-mRNA splicing decisions, and thus mediate alternative exon or intron inclusion (33–38, 40–42, 44). Chromatin looping is a genome-wide function of CTCF placing it at the center of 3D chromatin architecture.
