WebCTCF is a nuclear protein initially discovered for its role in enhancer-promoter insulation. It has been shown to play a role in genome architecture and in fact, its DNA binding sites are enriched at the borders of chromatin domains. Recently, we showed that depletion of CTCF impairs the DNA damage response to ionizing radiation. To investigate the relationship … WebNov 1, 2024 · In the human genome, chromatin loops play an important role in regulating gene expression by connecting regulatory loci to gene promoters. The anchors of these loops are bound by the protein CTCF, which is required for loop formation and maintenance. CTCF binds a specific non-palindromic DNA sequence motif.

CTCF - Wikipedia

WebCCCTC-binding factor (CTCF) is a versatile transcription regulator that is evolutionarily conserved from fruit fly to human. CTCF binds to different DNA sequences through combinatorial use of 11-zinc fingers, and shows distinct functions (transcription activation/repression and chromatin insulation) depending on the biological context 1,2.
