The paper identifies redox regulation of ATG5's Cys19 as critical for autophagy initiation under nutrient restriction in human cells and mice.

Site-resolved redox proteomics of human muscle after three exercise types shows modality-specific cysteine oxidation, and a p62 Cys113 switch tied to autophagy in myotubes and mitochondrial remodeling in mice.

This study maps zinc-regulated cysteine sites in the human proteome, identifies cancer dependencies, and reveals a mechanism of zinc-induced cytotoxicity in lung cancers.
