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. WebThe minimal deleted area (MDA; see inset) affects the CTCF locus including all 11 zinc fingers. (B) Positions of heterozygous point mutations in or near splice acceptor sites (in dark blue) and missense (in light blue), nonsense (in orange), and insertion mutations (in red) in the coding regions of CTCF transcript ENST00000264010.

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 … WebBACKGROUND: CTCF (CCCTC-binding factor) is an evolutionarily conserved zinc finger protein involved in diverse functions ranging from negative regulation of MYC, to chromatin insulation of the ... earth walker shoesTranscriptional repressor CTCF also known as 11-zinc finger protein or CCCTC-binding factor is a transcription factor that in humans is encoded by the CTCF gene. CTCF is involved in many cellular processes, including transcriptional regulation, insulator activity, V(D)J recombination and regulation of … See more CCCTC-Binding factor or CTCF was initially discovered as a negative regulator of the chicken c-myc gene. This protein was found to be binding to three regularly spaced repeats of the core sequence CCCTC and thus … See more The primary role of CTCF is thought to be in regulating the 3D structure of chromatin. CTCF binds together strands of DNA, thus forming chromatin loops, and anchors DNA to cellular … See more CTCF binds to the consensus sequence CCGCGNGGNGGCAG (in IUPAC notation).
