Deubiquitinating enzymes (DUBs), also known as deubiquitinating peptidases, deubiquitinating isopeptidases, deubiquitinases, ubiquitin proteases, ubiquitin hydrolases, ubiquitin isopeptidases, are a large group of proteases that cleave ubiquitin from proteins and other molecules.

Karpel-Massler et al target deubiquitinases for glioblastoma therapy by utilizing the small-molecule inhibitor WP1130.
