This chapter provides detailed methodology and materials required to profile deubiquitinases (DUBs) in a cellular matrix using specific activity-based probes, with immunoblotting and mass spectrometry proteomics-based readouts. Different types of activity-based protein profiling (ABPP) for studying the potency and selectivity of DUB inhibitors are outlined here, including the standard ABPP, the deep DUBome ABPP, and the ABPP-HT (high-throughput compatible).
