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. WebJan 8, 2024 · Methods We collated somatic CTCF mutations from cancer genome portals and published studies to determine their nature, frequency, distribution and potential functional impact. We undertook an in-depth examination of 5 CTCF missense zinc finger (ZF) mutations occurring within key intra- and inter-ZF residues. We performed functional … 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 ability of CTCF; instead, they selectively blocked binding to some CTCF target sites, but not to others ( 25 ). flagowy smartfon xiaomi
