Ctcf zinc fingers

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 … WebCTCF is a ubiquitous 11 zinc finger (ZF) protein with highly versatile functions. A transcriptional repressor, CTCF, binds to promoters of vertebrate c-myc gene. It also binds to the PLK and PIM1 promoters. CTCF may prevent the access of transcriptional activators to enhancers. CTCF also acts as a transcriptional activator of APP.
