Genome-wide characterization of mammalian promoters with distal enhancer functions

Salvatore Spicuglia and colleagues use a high-throughput reporter assay to identify a set of mammalian promoters, termed Epromoters, that display enhancer activity and have distinct genomic and epigenomic features. Through CRISPR–Cas9 gene editing experiments, they show that Epromoters are involved in long-range gene regulation in cis.
