Abstract
It is often the case in biology that research into breaking things down lags behind research into synthesizing them, and this is certainly true for intracellular proteolysis. Now that we recognize that intracellular proteolysis, triggered by attaching multiple copies of a small protein called ubiquitin to target proteins, is fundamental to life, it is hard to believe that 20 years ago this field was little more than a backwater of biochemistry studied by a handful of laboratories. Among the few were Avram Hershko, Aaron Ciechanover and Alexander Varshavsky, who were recently awarded the Albert Lasker award for basic medical research for discovering the importance of protein degradation in cellular physiology. This Timeline traces how they and their collaborators triggered the rapid movement of ubiquitin-mediated proteolysis to centre stage.
