Webmediate cohesion. But contrary to this expectation, cohesin is enriched at thousands of well-defined loci on chromosome arms. In mammalian genomes, ~90% of these are defined by binding sites for CCCTC binding factor CTCF (Parelho et al, 2008; Wendt et al, 2008). CTCF is a zinc-finger protein that has been implicated WebJan 27, 2024 · Crystal Structure. Li et al. (2024) showed that a segment within the CCCTC-binding factor (CTCF; 604167) N terminus interacts with the SA2-SCC1 subunits of human cohesin.They reported a crystal structure of SA2-SCC1 in complex with CTCF at a resolution of 2.7 angstroms, which revealed the molecular basis of the interaction.
WebIn CTCF-depleted cells, most of the cohesin-bound sites are unperturbed, indicating overlapping as well as distinct functions of CTCF and cohesin in genome organization [36,60,61]. Interestingly, cohesin copurifies and colocalizes with mediator complex, which is recruited mostly to activate gene promoters and enhancers [62,63] .
