Abstract
Transcriptional regulators often act as central hubs to integrate multiple nutrient and stress signals. In this issue, Qiao et al. (2017. J. Cell Biol. https://doi.org/10.1083/jcb.201607091) demonstrate how heat shock factor 1 (HSF1) uncouples metabolic control from proteostatic regulation and unveils HSF1 as a critical transcriptional regulator of NAD(+) metabolism.
