WebJun 30, 2024 · The underlying DNA extrusion scenario is characterized by a divergent CTCF pair and the imbalanced DNA extrusion activities which pull the promoters to a specific direction. Our findings proposed that most promoters do not contact enhancers directly. In contrast, promoters and enhancers are brought in proximity by the convergent CTCF … Webto species-specific CTCF sites, which are located within the larger domains. An analysis of the patterns of interac-tion across CTCF-binding sites at loop termini shows a striking correlation between conservation and strong in-sulation.

WebOct 27, 2024 · CTCF and RNAPII loops. We used CTCF and RNAPII loops identified in the ChIA-PET experiment [Supplementary Information). For the feature selection and classifier evaluation we used 70.9% loops out of all the CTCF convergent loops (79.1% and 99.9% for CTCF tandem and RNAPII loops respectively). WebCTCF–RNA interaction appears to be important for regu-lation of p53 expression. Kung et al.
