By opposing protein ubiquitylation, deubiquitylating enzymes (DUBs) regulate various cellular processes, including protein degradation, the DNA damage response, cell signalling and autophagy. Many DUBs show high specificity for ubiquitin chain architecture and/or the protein substrate that they recognize, and have emerged as exciting therapeutic targets within the field of proteostasis.
