Small molecules as tools for functional assessment of deubiquitinating enzyme function
Cell Chemical Biology(2021)
摘要
Deubiquitinating enzymes (DUBs) are a largely understudied and untapped resource in the toolkit of protein degradation functionalities. They comprise a large repertoire of enzymes that remove ubiquitin from substrates in a variety of cellular and pathophysiological contexts, and have enormous potential for research and clinical use. It is only within the last 5 years that potent, selective, and well-characterized small-molecule inhibitors of DUBs have been described. These compounds are now being used to study the biological roles of DUBs. Here, we describe downstream applications of small-molecule inhibitors for studying DUBs and provide a framework for future studies. We highlight recent examples of using these inhibitors to confirm and explore the role of these enzymes in both normal and pathological contexts. These studies represent the first steps in the burgeoning field of pharmacological and chemoproteomic studies of DUBs, which will be critical for the continued advancement of DUB field.
