Abstract

The evolutionally conserved and abundant post-translational modifier ubiquitin (Ub) is involved in a vast number of cellular processes. Imbalanced ubiquitination is associated with a range of diseases. Consequently, components of the ubiquitylation machinery, such as deubiquitinating enzymes (DUBs) that control the removal of Ub, are emerging as therapeutic targets. Here, we describe a robust assay suitable for small-molecule inhibitor screening. This assay has the potential to drive the development of small-molecule compounds that can selectively target DUBs.
