WebAug 28, 2024 · Author summary Properly regulated gene expression in time and space during development and differentiation requires not only transcriptional inputs, but also specific structuring of the chromatin. CTCF is a DNA binding factor that is believed to be critical for this process through binding to tens of thousands of sites across the genome. … WebOct 30, 2024 · Cohesin has a similar effect, but it is pronounced only when cohesin co-binds with CTCF. None of other DNA-binding proteins showed such behaviour (Figure 2). This uniqueness of CTCF can be explained by the large variability of its binding affinity through different combinations of its 11 zinc fingers that allows creating a ‘CTCF code’ …

WebOct 6, 2024 · Cleavage of RAD21 in NBS1 buffer eliminated CTCF–CTCF looping interactions, while cohesin-dependent elevated intra-TAD interactions were reduced by only 40–60% (Fig. 3i). Given that 50% of ... WebWe found only 41 differentially called CTCF-binding peaks out of a total of 31,840 called peaks (Figures 2 A and S2; Table S3). Interestingly, 5 out of these 41 binding peaks that were conserved in CTCF-deleted patients correspond to the TCRAD locus and were lost in CTCF wild-type patients with T-ALL due to TCRD recombination (Figure 2 B).
WebMay 11, 2024 · Ubiquitously expressed CTCF is involved in numerous cellular functions, such as organizing chromatin into TAD structures. In contrast, its paralog, CTCFL, is normally only present in the testis. However, it is also aberrantly expressed in many cancers. While it is known that shared and unique zinc finger sequences in CTCF and … WebUsing ChIP-seq in CTCF-AID cells after 2 days of auxin, we detected only 27% of the initial CTCF peaks. (Figures S1B and S1C and Table S4). The enrichment level in persistent peaks was severely reduced (Figures S2D and S2E), indicating that CTCF occupancy is lost or considerably lower at all of its binding sites after depletion.
WebApr 10, 2024 · CTCF, which regulates chromatin architecture, was first identified as an insulator protein that prevents gene expression by blocking enhancer-promoter interactions, and subsequent studies revealed the ability of CTCF to facilitate the formation of TADs and intra-TAD loops. 20, 21 CTCF expression is vital for cell survival, and CTCF-dependent ... WebApr 10, 2024 · How changes in spatial chromatin organization are integrated into the network of molecular mechanisms mediating CD8+ T cell effector functions and memory formation is not well understood. Quon et al. characterize genome interactions accompanying the CD8+ T cell response to infection and find that the DNA architectural …
Transcriptional repressor CTCF also known as 11-zinc finger protein or CCCTC-binding factor is a transcription factor that in humans is encoded by the CTCF gene. CTCF is involved in many cellular processes, including transcriptional regulation, insulator activity, V(D)J recombination and regulation of chromatin architecture.
WebMar 30, 2024 · In control cells, CTCF-only sites or the CTCF/SATB1 co-occupied sites preferentially interact with each other, giving rise to strong dot-like signals at the center of pile-up heatmaps (Figure 5D). However, such a pattern was not observed for the SATB1-only loops (Figure 5D). Therefore, SATB1 does not mediate chromatin looping … read mrcWebConsistently, mutating RBRs in CTCF only disrupts a subset of loops [Citation 36, Citation 37] and CTCF binding can be regulated [Citation 141, Citation 142].
