Enhancer-promoter communication: hubs or loops?

Abstract
There has been a sea change in our view of transcription regulation during the past decade (Fukaya et al., 2016, Lim et al., 2018, Hnisz et al., 2017 [3], Liu et al., 2018 [4], Kato et al., 2012). Classical models of enhancer-promoter interactions and the stepwise assembly of individual RNA Polymerase II (Pol II) complexes have given way to the realization that active transcription foci contain clusters-hubs-of transcriptional activators and Pol II. Here we summarize recent findings pointing to the occurrence of transcription hubs and the implications of such hubs on the regulation of gene activity.
