Article: Science of cell protein destruction wins Nobel?| New Scientist

Discoveries concerning the controlled process of cell protein degradation have earned three scientists the Nobel Prize in Chemistry for 2004. Aaron Ciechanover and Avram Hershko from the Technion, Israel Institute of Technology, Haifa, and Irwin Rose from the University of California, Irvine, share the $1.3 million prize for discovering the process by which a protein called ubiquitin attaches itself to unwanted proteins, giving them the “kiss of death” that marks them for destruction.
