| ubiquitin | <protein> A protein (8.5 kD) found in all eukaryotic cells. Can be linked to the lysine side chains of proteins by formation of an amide bond to its C terminal glycine in an ATP requiring process. The protein/ubiquitin complex is subject to rapid proteolysis. Ubiquitin also has a role in the heat shock response. (18 Nov 1997) |

| ubiquitin |
A 76-amino-acid protein that can be covalently attached to specific lysine residues in target proteins. This often forms multimeric polyubiquitin chains, which is thought to target the protein for destruction.

| ubiquitin |
A protein found in all eukaryotic cells that becomes covalently attached to certain residues of other proteins. The attachment of a chain of ubiquitins tags a protein for intracellular proteolytic destruction.

| ubiquitin |
Ubiquitin is associated with proteins that are about to break down. Their usual function is probably to protect proteins. In many dementias an accumulation of ubiquitinated proteins is found--for example, in Lewy bodies.
