Abstract:

Proteomic cysteines play important roles in maintaining and regulating redox homeostasis in cells; they also act as functional active site in many proteins and participate in many physiological processes. In addition, post-translationally modifying proteomic cysteines also extends protein functional diversity. The development of chemical proteomics and activity-based protein profiling (ABPP) has led to many important improvements that enable cysteines and their post-translational modifications to be explored. In this paper, we briefly introduce ABPP methods for the proteome-wide profiling of cysteines, present the latest proteomics research into protein-based cysteines and their post-translational modifications, and discuss future developmental trends in this field.

Key words: Cysteine, Protein post-translational modifications, Activity-based protein profiling, Chemical probes
