Ubiquitin-binding domains.

The covalent modification of proteins by ubiquitination is a major regulatory mechanism of protein degradation and quality control, endocytosis, vesicular trafficking, cell-cycle control, stress response, DNA repair, growth-factor signalling, transcription, gene silencing and other areas of biology. A class of specific ubiquitin-binding domains mediates most of the effects of protein ubiquitina...

Ubiquitin and its binding domains.

Post-translational modification by ubiquitin (ubiquitination, ubiquitylation, ubiquitinylation) is used as a robust signaling mechanism in a variety of processes that are essential for cell homeostasis. Its signaling specificity is conferred by the inherent dynamics of ubiquitin, the multivalency of ubiquitin chains, and its subcellular context, often defined by ubiquitin receptors and the subs...

ESCRT ubiquitin-binding domains function cooperatively during MVB cargo sorting

Ubiquitin (Ub) sorting receptors facilitate the targeting of ubiquitinated membrane proteins into multivesicular bodies (MVBs). Ub-binding domains (UBDs) have been described in several endosomal sorting complexes required for transport (ESCRT). Using available structural information, we have investigated the role of the multiple UBDs within ESCRTs during MVB cargo selection. We found a novel UB...

Structural insights into specificity and diversity in mechanisms of ubiquitin recognition by ubiquitin-binding domains.

UBDs [Ub (ubiquitin)-binding domains], which are typically small protein motifs of <50 residues, are used by receptor proteins to transduce post-translational Ub modifications in a wide range of biological processes, including NF-κB (nuclear factor κB) signalling and proteasomal degradation pathways. More than 20 families of UBDs have now been characterized in structural detail and, although ma...
