The chromatin remodeller CHD4 regulates transcription factor binding to both prevent activation of silent enhancers and maintain active regulatory elements
CHD4 directly limits transcription factor binding to chromatin, which prevents activation of silent or cryptic enhancers but facilitates activity of active enhancers.
