WebKeywords: CTCF, p53, breast cancer . Introduction. CCCTC-binding factor (CTCF) is a widely expressed 11-zinc finger multifunctional protein that is involved in different aspects of gene regulation including promoter … WebCCCTC-binding factor ( CTCF ), an 11- zinc finger factor involved in gene regulation, utilizes different zinc fingers to bind varying DNA target sites. CTCF forms methylation-sensitive insulators that regulate X-chromosome inactivation. Transcriptional repressor CTCFL (this protein) is a paralog of CTCF and appears to be expressed primarily in ...
WebMoreover, overexpression of CTCF in B-cell lymphoma leads to apoptosis, downregulation of c-Myc oncogene, and upregulation of P53 target genes. CTCF’s role in tumor suppression is further demonstrated in vivo using CTCF hemizygous knockout mice, which have a significantly higher chance to succumb to different types of cancer including uterine ... Transcriptional 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). This sequence is defined by 11 zinc finger motifs in its structure. CTCF's binding is disrupted by See more • Ohlsson R, Renkawitz R, Lobanenkov V (2001).

WebMay 5, 2010 · CTCF knockdown leads to increased basal expression of PUMA concomitant with a reduction in chromatin boundary signatures. Importantly, derepression of PUMA upon CTCF depletion occurs without p53 activation or activation of other p53 target genes. Therefore, CTCF plays a pivotal role in dampening the p53 apoptotic response by acting …
