The 20S proteasome was discovered in 1980 and the 26S proteasome six years later. Research over the past two decades has made it abundantly clear that the Ub-proteasome system is of central importance in eukaryotic cell physiology and medicine. At the cellular and biochemical levels, there are a number of unresolved problems. We need a crystal structure of the 19S RC, or better yet, the 26S proteasome, for they would surely provide an insight into the mechanism by which the 26S proteasome degrades its substrates. How the 26S proteasome itself is regulated and the extent to which proteasomal components vary among tissues in higher eukaryotes are other important unresolved problems. As for the medical perspective, we need to know how many diseases will be found to arise because of defects in the ubiquitin–proteasome system. Hopefully, these problems will generate research on the UPS by some readers of this article.
