CTCF and Cohesin (Rad21) ChIP-seq in male mouse liver

Sequencing files provided here include mouse liver ChIP-seq for CTCF and the cohesin subunit Rad21. These files are part of a larger study where we describe features of Topologically Associating Domains (TADs) and their impact on liver gene expression, then use these features to computationally predict subTAD structures not otherwise readily identifiable due to the low resolution of Hi-C. Our findings reveal that CTCF-based subTAD loops maintain key insulating properties of TADs, and support the proposal that subTADs are formed by the same loop extrusion mechanism and contribute to nuclear architecture as intra-TAD scaffolds that further constrain enhancer-promoter interactions. This allows high expression of super enhancer target genes and individual genes within inactive TADs, and may be a broadly conserved mechanism of genomic regulation.
