Site-specific Identification of Glutathionylation


ABSTRACT: Cardiomyocytes proteins were investigated for their glutathionylation in response to hydrogen peroxide generated from glucose oxidase and using a clickable glutathione derivative. After exposure, or not, to hydrogen peroxide the glutathionylated proteins were enriched and LC-MS/MS analyses was performed.

Reactive oxygen species (ROS) are important signaling molecules, but their overproduction is associated with many cardiovascular diseases, including cardiomyopathy. ROS induce various oxidative modifications, among which glutathionylation is one of the significant protein oxidations that occur under oxidative stress. Despite previous efforts, direct and site-specific identification of glutathionylated proteins in cardiomyocytes has been limited. In this report, we used a clickable glutathione ap  ...[more]
