This book aims to advance the understanding of deubiquitinases (DUBs) and DUB-like enzymes. Chapters detail methods used to identify, classify,and biochemically characterize DUBs along with approaches that enable both the determination and alteration of DUB biological function.. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols. Authoritative and cutting-edge, Deubiquitinases: Methods and Protocols aims to be a useful and practical guide to new researchers and experts looking to expand their knowledge.
