The Nobel Prize in Chemistry 2004

	The Nobel Prize in Chemistry 2004				The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry for 2004 "for the discovery of ubiquitin-mediated protein degradation" jointly to Aaron Ciechanover, Avram Hershko and Irwin Rose

Proteins that are marked for hacking into small pieces

It has long been clear how proteins are built up in the cell. But the opposite, how they are broken down, was long thought to be less exciting to study. This year's Nobel Laureates, Aaron Ciechanover, Avram Hershko and Irwin Rose, went against the stream and, at the beginning of the 1980s, discovered one of the cell's most important control mechanisms, controlled protein degradation.

The discovery was made at the beginning of the 1980s at the Fox Chase Cancer Center in Philadelphia, USA, jointly by the three scientists.
