Ctcf anchor
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 … 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. In each case, it is unknown if CTCF directly evokes the outcome or if it does so indirectly (in … 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).
