Pioneering EBF2 remodels the brown fat chromatin landscape

In this issue of Genes & Development, Shapira and colleagues (pp. 660-673) outline mechanisms by which the brown fat transcription factor early B-cell factor 2 (EBF2) selectively activates brown lineage-specific gene expression. The investigators show that EBF2 interacts with and recruits a tissue-specific BAF chromatin remodeling complex to brown fat gene enhancers, thereby regulating chromatin accessibility. Their findings provide important insight into epigenetic regulation of adipocyte fate and thermogenic gene expression.
