Abstract
S-Nitrosylation, the modification of a cysteine thiol by a nitric oxide (NO) group, has emerged as an important posttranslational modification of signaling proteins. An impediment to studying the regulation of cell signaling by S-nitrosylation has been the technical challenge of detecting endogenously S-nitrosylated proteins. Detection of S-nitrosylated proteins is difficult because the S-NO bond is labile and therefore can be lost or gained artifactually during sample preparation. Nevertheless, several methods have been developed to measure endogenous protein S-nitrosylation, including the biotin switch assay and the chemical reduction/chemiluminescence assay. This chapter describes these two methods and provides examples of how they have been used successfully to elucidate the role of protein S-nitrosylation in cell physiology and pathophysiology.
