Developmentally programmed loss of long-range Polycomb interactions is regulated by cohesin
Distal regulatory elements (DREs), such as enhancers, can regulate genes across megabase-long distances, presumably via coming into close spatial proximity. The establishment of new transcriptional programmes during cell type transitions is associated with widespread rewiring of the spatial organisation of the genome, including gain and loss of chromatin interactions. Extensive effort has been…
