Deskripsi

Most insights into deubiquitinase (DUB) substrate specificity originate from studies with isolated di-ubiquitins (diUb), but in cells diUbs with different linkage types coexist. Here, the authors develop a mass spectrometric DUB activity assay that can probe all diUbs simultaneously under substrate competition conditions.
