ReviewRegulation of protein function by glutathionylation
Abstract
The main function of reduced glutathione (GSH) is to protect from oxidative stress as a reactive oxygen scavenger. However, in the context of redox regulation, the ratio between GSH and its oxidized form (GSSG) determines the redox state of redox-sensitive cysteines in some proteins and, thus, acts as a signaling system. While GSH/GSSG can catalyze oxido-reduction of intra- and inter-chain disulfides by thiol-disulfide exchange, this review focuses on the formation of mixed disulfides between glutathione and proteins, also known as glutathionylation. The review discusses the regulatory role of this post-translational modification and the role of protein disulfide oxidoreductases (thioredoxin/thioredoxin reductase, glutaredoxin, protein disulfide isomerase) in the reversibility of this process.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
