  1. ...to the formation and maintenance of TADs (Guo et al. 2015). Given that our CUT&RUN data revealed distinct losses and gains of CTCF and cohesin binding following Wnt activation, we wondered whether Wnt perturbation could induce 3D architectural alterations in the . Hence, we conducted HiChIP against CTCF for Wnt...
  2. ...al. (2021) showed the collaborative role of MAZ and CTCF in controlling cohesin positioning and organization, and Clouaire et al. (2005) suggested that cellular THAP proteins may serve as zinc-dependent sequence-specific DNA-binding factors, playing crucial roles in chromosome segregation, chromatin...
  3. ...and transcriptional regulation by mediating chromatin loop formation with cohesin, which acts as an insulator and contributes to the establishment of topologically associated domains (TADs) (Dixon et al. 2012; Nora et al. 2017). A large fraction of CTCF binding sites are shared across multiple cell types...
  4. ...IP-seq (Johnson et al. 2007) on formaldehyde-fixed sperm chromatin sheared via sonication (Methods) (Fig. 5; Supplemental Fig. S6). We focused on a sequence-specific DNA-binding protein, CTCF, and the histone modifications H3K4me3 and H3K27me3 (K4/27), as these epitopes were expected to show distinctive...
  5. ...Jun Kim, Haoyu Wang and Sevinç Ercan Department of Biology, Center for Genomics and Systems Biology, New York University, New York, New York 10003, USA Corresponding author: sevinc@nyu.eduAbstractIn mammals, cohesin and CTCF organize the 3D into topologically associating domains (TADs) to regulate...
  6. ...chromatin loops between convergent CTCF sites (van Ruiten and Rowland 2021). The genomic positions of boundaries and dots anchor all display enrichment for cohesin by ChIP-seq. Acute depletion of CTCF leads to -wide loss of TADs and dots in Hi-C contact maps as well as a loss of cohesin ChIP-seq enrichment...
  7. ...enhanced contact frequency within themselves (Dixon et al. 2012; Nora et al. 2012; Rao et al. 2014). Loops often demarcate contact domains by physical tethering of a pair of loci, which are mediated by the insulator protein CTCF and the ring-shaped cohesin complex (Nora et al. 2017; Rao et al. 2017...
  8. ...identifies both contact and loop domain TADs based on intra-domain interaction frequency. Both TADs and loops are thought to be formed by loop extrusion and to be dependent on CTCF and cohesin (Nora et al. 2017; Rao et al. 2017; Schwarzer et al. 2017; Wutz et al. 2017). HOMER identified 15,397 TAD boundaries...
  9. ...their associations, which may involve both inter- and intra-enhancer interactions (Rao et al. 2017; Rosencrance et al. 2020). However, in normal cycling cells, these sub-TAD size interactions have been shown to have Med12/cohesin (lacking CTCF) (Phillips-Cremins et al. 2013). These observations in cultured mammalian...
  10. .... Xenopus laevis egg extracts assemble centromeres in vitro, providing a system for studying centromeric DNA functions. However, centromeric sequences in Xenopus laevis have not been extensively characterized. In this study, we combine Cenpa ChIP-seq with a k-mer based analysis approach to identify...
