Editor’s summary Hypertrophy of white adipose tissue due to triglyceride storage and steatosis in the liver due to excessive de novo lipogenesis have detrimental metabolic effects. Venetos et al. found that these processes were stimulated by the enzymatic removal of S-nitrosyl (SNO) groups from distinct protein targets in white adipose tissue and liver by the denitrosylase SCoR2.

Abstract An increased level of phosphorylation of eukaryotic translation initiation factor 2 subunit-α (eIF2α, encoded by EIF2S1; eIF2α-p) coupled with decreased guanine nucleotide exchange activity of eIF2B is a hallmark of the ‘canonical’ integrated stress response (c-ISR)1. It is unclear whether impaired eIF2B activity in human diseases including leukodystrophies2, which occurs in the absence of eIF2α-p induction, is synonymous with the c-ISR.
