Background: Nitric oxide (NO) regulates a variety of cellular functions. One mechanism by which NO may exert its influence is through formation of S-nitrosothiols at critical thiol residues in protein-active sites, including those of nuclear protein transcription factors. Methods: NF-κB p50 and AP-1 c-jun were S-nitrosylated in the presence of acidic NaNO 2 . Wild-type protein and protein...
Nitric oxide (NO) regulates a wide variety of cellular functions, in part, by formation of S–NO bonds at critical active site thiol groups within proteins, including transcription factors. Previous studies have qualitatively demonstrated that S-nitrosothiol formation can alter transcription factor binding to the DNA recognition site. To more precisely define the effect of S-nitrosylation on transcription...
