Proteomics-Based Identification of DUB Substrates Using Selective Inhibitors

Deubiquitinating enzymes (DUBs) catalyze the removal of ubiquitin, thereby reversing the activity of E3 ubiquitin ligases and are central to the control of protein abundance and function. Despite the growing interest in DUBs as therapeutic targets, cellular functions for DUBs remain largely unknown and technical challenges often preclude the identification of DUB substrates in a comprehensive manner. Here, we demonstrate that treatment with...
