L'ubiquitination est une modification post-traductionnelle qui joue un rôle important dans les processus cellulaires et est étroitement coordonnée par la désubiquitination. Les défauts dans les deux réactions sous-tendent les pathologies humaines. Nous fournissons des protocoles pour mener la réaction d'ubiquitination et de deubiquitination in vitro utilisant des composants purifiés.
