Stress to the cell causes protein denaturation: the protein molecule loses its native functional conformation when it unfolds. Chaperones assist the damaged molecule to regain its functional conformation.
If cellular stress proceeds unchecked by such antistress mechanisms as the protein-refolding action of chaperones, intracellular proteins become denatured and insoluble.
These denatured proteins tend to stick to one another, precipitate, and form inclusion bodies. The development of (...)

S-nitrosylation
14 April 2004S-nitrosylation is a ubiquitous redox-related modification of cysteine thiol by nitric oxide (NO), which transduces NO bioactivity. Accumulating evidence suggests that the products of S-nitrosylation, S-nitrosothiols (SNOs), play key roles in human health and disease.
