Identification of proteins undergoing glutathionylation in oxidatively stressed hepatocytes and hepatoma cells.

Abstract

Protein glutathionylation is a post-translational modification consisting of the formation of a mixed disulfide between protein cysteines and glutathione (GSH). To identify proteins undergoing glutathionylation in primary rat hepatocytes and in human HepG2 hepatoma cells, we radiolabeled the intracellular GSH pool with L-[(35)S] cysteine. Cells were then… (More)
