Ubiquitin is a small (8.6 kDa) regulatory protein found in most tissues of eukaryotic organisms, i.e., it is found ubiquitously. It was discovered in...

A ubiquitin ligase (also called an E3 ubiquitin ligase) is a protein that recruits an E2 ubiquitin-conjugating enzyme that has been loaded with ubiquitin...

protein called ubiquitin. The tagging reaction is catalyzed by enzymes called ubiquitin ligases. Once a protein is tagged with a single ubiquitin molecule,...

transfer of SUMO protein to other proteins). The Small Ubiquitin-related Modifier, SUMO-1, is a ubiquitin-like family member that is conjugated to its substrates...

Deltex E3 ubiquitin ligase 3L is a protein that in humans is encoded by the DTX3L gene. It functions as an ubiquitin ligase (E3), and is over-expressed...

encoded by the UBC gene in humans. Polyubiquitin-C is one of the sources of ubiquitin, along with UBB, UBA52, and RPS27A. UBC gene is one of the two stress-regulated...

Ubiquitin is a protein that in humans is encoded by the UBB gene. Ubiquitin is one of the most conserved proteins known in eukaryotic organisms. Ubiquitin...

Ubiquitin-binding domains (UBDs) are protein domains that recognise and bind non-covalently to ubiquitin through protein-protein interactions. As of 2019...

Linear ubiquitin chain assembly complex (LUBAC) is a multi-protein complex and the only known E3 ubiquitin ligase able to conjugate ubiquitin in a head-to-tail...

In molecular biology, the Ubiquitin-Interacting Motif (UIM), or 'LALAL-motif', is a sequence motif of about 20 amino acid residues, which was first described...
