WebAug 23, 2024 · Previous studies show that chromatin loops are mediated by architectural proteins CCCTC-binding factor (CTCF) and cohesin through extrusion, in which CTCF motif binds to a specific non-palindromic motif in a convergent orientation at two sites and acts as a loop anchor ( Fudenberg et al., 2016; Salameh et al., 2024; Sanborn et al., 2015 ). WebOct 30, 2024 · CTCF has ∼100 000 potential binding sites in the mouse genome. Usually there are ∼30 000–60 000 CTCF sites bound in a given cell type, which translates to about 1 million of affected nucleosomes (up to 10% of the mouse genome) ( 11–14 ).
