WebNov 25, 2024 · Recently, Li et al. provided crucial insights into the molecular mechanism underpinning the dynamic regulation of chromatin folding by cohesin and CTCF, demonstrating that a fragment within the CTCF N-terminus, not including the zinc finger domains, interacted with the SA2-SCC1 subunits of human cohesin . This observation … 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 …
Web5.1 CTCF genome organizer and the cohesin complex. CTCF (CCCTC-binding factor) is a multiple zinc finger protein that exerts diversified functions under different genomic … WebMar 6, 2024 · However, the role of CTCF in DNA damage response remains elusive. Here, we show that CTCF is quickly recruited to the sites of DNA damage. The fast recruitment is mediated by the zinc finger domain and poly (ADP-ribose) (PAR). Further analyses show that only three zinc finger motifs are essential for PAR recognition.
WebFeb 16, 2024 · Silencing CTCF or COL1A1/COL1A3 markedly inhibited cell growth and migration in the metastatic GC cell line BGC823. Collectively, this ECM-related 7-gene signature provides a novel insight for survival prediction among GC patients. The zinc finger protein CTCF regulates ECM-related genes, thereby promoting GC cell growth … WebMay 11, 2024 · Ubiquitously expressed CTCF is involved in numerous cellular functions, such as organizing chromatin into TAD structures. In contrast, its paralog, CTCFL, is normally only present in the testis. However, it is also aberrantly expressed in many cancers. While it is known that shared and unique zinc finger sequences in CTCF and CTCFL …

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 structures like the nuclear lamina. It also defines the boundaries between active and … See more CTCF binds to itself to form homodimers. CTCF has also been shown to interact with Y box binding protein 1. CTCF also co-localizes with cohesin, which extrudes chromatin loops by actively translocating one or two DNA strands through its ring-shaped structure, … See more • CCCTC-binding+factor at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • FactorBook CTCF See more The binding of CTCF has been shown to have many effects, which are enumerated below.
