WebNov 1, 2014 · CTCF is an 11-zinc finger (ZF) protein flanked by unstructured N- and C-terminal polypeptides, containing ∼727 amino acids and two transcription repressor domains, with flexible binding to divergent regulatory DNA sequences [ 28 – 30 ]. 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 heterochromatic DNA. Since the 3D structure of DNA influences the regulation of genes, CTCF's activity influences the expression of genes. CTCF is thought to be a primary part of the activity of insulators, sequence…
