Proteomic analysis of S-nitrosylation and denitrosylation by resin-assisted capture

Abstract: We have modified the biotin switch assay for protein S-nitrosothiols (SNOs), using resin-assisted capture (SNO-RAC). Compared with existing methodologies, SNO-RAC requires fewer steps, detects high-mass S-nitrosylated proteins more efficiently, and facilitates identification and quantification of S-nitrosylated sites by mass spectrometry. When combined with iTRAQ labeling, SNO-RAC revealed that intracellular proteins may undergo rapid denitrosylation on a global scale. This methodology is readily adapted to an… Show more

“…Nitrosylation of Prx1 in Cells-To investigate S-nitrosylation of endogenous Prx1, we exposed RAW264.7 macrophages to CysNO treatment and assayed for SNO-Prx1 formation with the SNO-RAC method (21). Similar to the in vitro results, endogenous Prx1 was rapidly nitrosylated in response to treatment with CysNO, with maximal nitrosylation observed at the 5-min time point (Fig.…”

“…Nitrosylation likewise inhibits the activity of plant Prx II E (20). Prx1 was found to be nitrosylated in endotoxin-stimulated macrophages (21,22), and recent studies indicate that nitrosylation protects Prx1 from over-oxidation (23). Despite these reports, it remains to be established exactly how S-nitrosylation controls the structure and function of distinct Prx proteins and, more generally, how and to what extent SNOs and H 2 O 2 cross-regulate each other's function.…”

“…Accordingly, in most instances, the time course of these processes might not be rate limiting for the overall events that comprise NMDAR activation, stimulation of nNOS to generate NO, nitrosylation of stargazin, and its translocation along with GluR1. However, in some cases, both basal and stimulated denitrosylation take place over varied time scales (20)(21)(22)(23)(24). In the case of stargazin-mediated GluR1 surface expression, nitrosylation of stargazin does not have an obligate role in trafficking; instead, it exerts a regulatory influence.…”

“…2C) have been previously identified by MS-based analyses of SNO-treated RAW246.7 macrophages or brain extracts, respectively (23,50,61). Inasmuch as the in vitro targets of SNOs (e.g., in tissue extracts) have been shown to significantly overlap the sets of proteins that are S-nitrosylated by endogenous NO (21), protein microarrays present a tractable methodology for deconvoluting the multiple pathways for S-nitrosylation and denitrosylation that govern steady-state SNO levels in vivo (12,61,62).…”
