WebJun 5, 2015 · Another important locus is the H19/Igf2 locus. The H19 and Igf2 genes are separated from each other by the imprinting control region (ICR), which can be conditionally methylated. 16 Methylation of the ICR is a decisive factor in CTCF binding because CTCF only binds the unmethylated ICR on the maternal chromosome. This CTCF binding …

WebApr 15, 2016 · The role of the zinc finger protein CTCF in organizing the genome within the nucleus is now well established. Widely separated sites on DNA, occupied by both CTCF and the cohesin complex, make physical contacts that create large loop domains. Additional contacts between loci within those domains, often also mediated by CTCF, tend to be … WebOct 30, 2024 · In the calculations involving CTCF motif directionality (Figures 5– 7) we first arranged predicted sites by the TRAP score into quintiles, and after that intersected them with the experimental ChIP-seq peaks of CTCF. Only motifs overlapping with sites that were experimentally detected by ChIP-seq in at least one mouse cell type were retained ...
WebThe protein CTCF plays a major role in large-scale organization of the genome. Binding sites for the protein MAZ are found adjacent to many CTCF sites. We show that, at such … WebFeb 1, 2024 · At the protocadherin α locus, disruption of CTCF/cohesin loop has been shown to diminish enhancer–promoter interaction and the level of gene expression [38, 39, 40]. Contrary, however, subsequent studies have reported that acute depletion of cohesin or CTCF only moderately impacts global transcription activities [34, 35]. This gives rise to ...

WebNov 1, 2014 · Despite the presence of 11 ZF domains in the CTCF protein sequence, only four of them are necessary to strongly bind to DNA, recognizing a core 12-bp DNA sequence [34, 36]. Binding of CTCF to DNA was first identified at the 5′-flanking CTC-rich DNA sequences of the CMYC gene, and it was termed the “CCCTC-binding factor” [29, 37].
WebThis raises the question of whether the properties of CTCF/MAZ double binding sites differ from those of CTCF-only sites. Most CTCF sites are associated with cohesin (8–12). CTCF is known to help form chromatin loop domains generated by the action of cohesin, which brings together pairs of distant sites on chromatin. how are elements organized on the ptWebCTCF is a nuclear protein initially discovered for its role in enhancer-promoter insulation.
