The magic of unraveling genome architecture and function

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 … WebAug 22, 2024 · Therefore, the stability of the association between CTCF and DNA can be linked to loop formation and the control of chromatin architecture.
