The ubiquity of ubiquitin

Attachment of the ubiquitin peptide to proteins plays a crucial role in targeting them for degradation. It also serves as a protein-marking mechanism in numerous other cellular processes, including endocytosis, signalling, ion transport and apoptosis. The final stage of the ubiquitylation reaction is usually catalyzed by E3 ubiquitin-protein ligases – of which there are many. In Cell Science at a Glance, Philip Robinson and Helen Ardley survey the different types of ubiquitin-protein ligase and remind us of some of the many roles of ubiquitylation in cells (see p. 5191 + poster).
