Facts (generated by robot; please edit if you find it inaccurate)

• Ubiquitin is attached to obsolete proteins, signaling to the cell that they are ready to be disassembled.
• Ubiquitination is a consequence of ubiquitin transfer between different proteins: ubiquitin is first activated in an ATP dependent manner by an ubiquitin-activating enzyme, called E1 (see figure).
• In this process, a small peptide called ubiquitin is linked to a protein in ways that can change the protein's function and location within the cell.
• The process of attaching a ubiquitin is called ubiquitination.
• Including new assay kits for Ubiquitinylation & SUMOylation.
