Recent studies have revealed that active enhancers are transcribed, producing a class of noncoding RNAs called enhancer RNAs (eRNAs). eRNAs are distinct from long noncoding RNAs (lncRNAs), but these two species of noncoding RNAs may share a similar role in the activation of mRNA transcription. Emerging studies, showing that eRNAs function in controlling mRNA transcription, challenge the idea that enhancers are merely sites of transcription factor assembly. Instead, communicationbetween promoters andenhancers canbebidirectional with promoters required to activate enhancer transcription. Reciprocally, eRNAs may then facilitate enhancer–promoter interaction or activate promoter-driven transcription.
