WebCTCF is an evolutionarily conserved zinc finger (ZF) phosphoprotein that binds through combinatorial use of its 11 ZFs to ∼50 bp target sites that have remarkable sequence variation. Formation of different CTCF–DNA complexes, some of which are methylation-sensitive, results in distinct functions, including gene activation, repression, silencing and …

WebJun 5, 2015 · CCCTC-binding factor (CTCF) is an 82-kDa protein with 11 zinc fingers. 1 It was first identified as a transcriptional repressor of the chicken c-myc gene, a regulatory gene that encodes the c-myc ...
WebMar 6, 2024 · However, the role of CTCF in DNA damage response remains elusive. Here, we show that CTCF is quickly recruited to the sites of DNA damage. The fast recruitment is mediated by the zinc finger domain and poly (ADP-ribose) (PAR). Further analyses show that only three zinc finger motifs are essential for PAR recognition. lithium ion formationWebDifferent subsets or combination of individual zinc fingers gives the ability to CTCF to recognize multiple DNA target sites.
