摘要
CCCTC-binding factor (CTCF) sites are enriched at the boundaries of topologically associated domains (TADs), but their function within TADs is unclear. Removal of sub-TAD CTCF sites adjacent to the alpha-globin enhancers is now shown to result in inappropriate activation of neighbouring genes. Intra-TAD enhancer insulation might be broadly important for tissue specificity of enhancers.
