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 … WebSimilar movements of both chromosome territories ruled out a specific GOF effect. Pluripotency gene activation was preceded by a transient, radial shift of GOF toward the nuclear interior. The persistent co-localization of GOF with its carrier chromosome territory rules out the formation of a giant chromatin loop during GOF activation.

WebOct 23, 2015 · The subunits would engage DNA in an antisymmetrical fashion, sliding in opposing directions (one forward and one reverse) until the presence of a CTCF motif on the appropriate strand is detected. In fact, ChIP-Seq data provide evidence of antisymmetrical positioning of the CTCF and cohesin proteins with respect to chromatin loop anchors.
