Definitions for ubiquitin
This page provides all possible meanings and translations of the word ubiquitin
A small polypeptide present in the cells of all eukaryotes; it plays a part in modifying and degrading proteins
Ubiquitin is a small regulatory protein that has been found in almost all tissues of eukaryotic organisms. It directs proteins to compartments in the cell, including the proteasome which destroys and recycles proteins. Ubiquitin can be attached to proteins and label them for destruction. This discovery won the Nobel Prize for chemistry in 2004. Ubiquitin tags can also direct proteins to other locations in the cell, where they control other protein and cell mechanisms.
U.S. National Library of Medicine
A highly conserved 76-amino acid peptide universally found in eukaryotic cells that functions as a marker for intracellular PROTEIN TRANSPORT and degradation. Ubiquitin becomes activated through a series of complicated steps and forms an isopeptide bond to lysine residues of specific proteins within the cell. These "ubiquitinated" proteins can be recognized and degraded by proteosomes or be transported to specific compartments within the cell.
