The Relationship Between Protein S-Nitrosylation and Human Diseases: A Review

Yadi Zhang et al. Neurochem Res. 2020 Dec.

Abstract

S-nitrosylation (SNO) is a covalent post-translational oxidative modification. The reaction is the nitroso group (-NO) to a reactive cysteine thiol within a protein to form the SNO. In recent years, a variety of proteins in human body have been found to undergo thiol nitrosylation under specific conditions. Protein SNO, which is closely related to cardiovascular disease, Parkinson's syndrome, Alzheimer's disease and tumors, plays an important role in regulatory mechanism of protein function in both physiological and pathological pathways, such as in cellular homeostasis and metabolism. This review discusses possible molecular mechanisms protein SNO modification, such as the role of NO in vivo and the formation mechanism of SNO, with particular emphasis on mechanisms utilized by SNO to cause certain diseases of human. Importantly, the effect of SNO on diseases is multifaceted and multi-channel, and its critical value in vivo is not well defined. Intracellular redox environment is also a key factor affecting its level. Therefore, we should pay more attention to the equilibrium relationship between SNO and denitrosylation pathway in the future researches. These findings provide theoretical support for the improvement or treatment of diseases from the point of view of SNO.
