WebPurpose: A previous study demonstrated that CTCF (CCCTC binding factor) regulates homeobox Pax6 gene expression in early embryonic stages and plays a dominant role in eye development. The purpose of the present study was to explore further the mechanism of CTCF controlling Pax6 gene expression in human retinoblastoma (Rb) cells and in the … 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 …
