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.

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. WebCTCF is a multivalent transcription factor and uses different combinations of zinc fingers (ZFs) to bind diverse target sequences . Tumor-derived point mutations in ZF3 and ZF7 did not totally abrogate the DNA-binding … iowa class battleship line drawing

WebThe CTCF protein The organization of the chicken and human CTCF loci is shown in Fig. 1a,b. The exon–intron organization is identical in mice and humans, as are the sequences of the entire promoter regions, 5 ′- and 3′-untranslated regions (UTRs) and each splice donor–acceptor site(G.N. Filipova et al., unpublished). Compared with the ... WebThe ubiquitously expressed CCCTC-binding factor (CTCF) is a highly conserved transcription factor carrying 11 zinc finger domains involved in multiple DNA sequence-specific recognition [1,2,3].Combinatorial use of zinc fingers is also responsible for CTCF pleiotropic functions including transcriptional activation/repression, insulator activity, and … WebJan 28, 2024 · Furthermore, CTCF-BORIS chimeric constructs provided evidence that, besides the N terminus of CTCF, the first two CTCF zinc fingers, and likely the 3D geometry of CTCF-DNA complexes, are also involved in cohesin retention. Based on this knowledge, we were able to convert BORIS into CTCF with respect to cohesin … oopiri meaning in english
