WebCTCF (CCCTC-binding factor) is a multiple zinc finger protein that exerts diversified functions under different genomic contexts. CTCF was first isolated and cloned on the basis of its ability to bind to highly divergent 50–60 bp sequences within the promoter region of the chicken Myc gene [153].

The results showed that CTCF and cohesin bind to DNA with different dynamics: …
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.
