|Background:||The ubiquitin-proteasome pathway is the principle pathway of proteolysis in eukaryotic cells and may contribute to controlling the intracellular levels of a variety of short-lived proteins (1-3), in addition to degrading abnormal proteins in the cytosol and nucleus. Protein substrates are marked with a poly-ubiquitin chain (4) and then degraded to peptides and free ubiquitin by a large multicatalytic complex, the proteasome, which exists within all eukaryotic cells (1-3). Numerous examples of regulatory proteins have been found to undergo ubiquitin-dependent proteolysis. Protein substrates of the ubiquitin-proteasome pathway include a number of cell regulatory molecules, such as cyclins, the Myc oncogene protein, and p53, and the regulated degradation of these molecules has been linked to the control of cell proliferation and cell cycle progression (5-7). By controlling the intracellular levels of such proteins, the activity of the ubiquitin-proteasome pathway might also be linked to apoptosis.|
