Nuclear receptors articles from across Nature Portfolio

The nuclear receptor REV-ERBα is a receptor for heme and plays a role in a range of physiological processes. Here, the authors provide the first structure of REV-ERB bound to a synthetic nonporphyrin ligand defining key mechanistic differences to how heme binds.

Mutations in PPARγ lead to lipodystrophy, but the mechanisms by which the mutations affect the activity in chromatin is unknown. Here, Madsen, Broekema et al. showed that mutations affecting two intermolecular interactions compromise chromatin remodeling.

Aryl hydrocarbon receptor (AHR) is a sensor of the chemical environment including pollutants, diet components and metabolites. Here, authors determine the structure of the indirubin-bound AHR cytosolic complex providing mechanistic insights into ligand-binding promiscuity and selectivity.

Nuclear receptors are transcription factors that transduce hormonal, nutrient, metabolite and redox signals into regulation of metabolic genes, in particular the transcriptional control of energy metabolism. Accordingly, nuclear receptors have central roles in adapting gene expression to changing energetic demands, thereby maintaining cellular energy homeostasis

Mature cardiac muscle requires high mitochondrial ATP production and specialized contractile proteins. Here the authors demonstrate that cardiomyocyte-specific contractile maturation involves cooperation between the nuclear receptor ERRγ and cardiogenic transcription factor GATA4, but ERRγ controls metabolic genes independently.
