Biography
Avram Hershko (Hebrew: אברהם הרשקו, Hungarian: Herskó Ferenc Ábrahám) was born on December 31, 1937, in Karcag, Hungary. He's a biochemist known for his pioneering research on protein degradation, which won him the Nobel Prize in Chemistry in 2004, shared with Aaron Ciechanover and Irwin Rose. His work changed the way we understand how cells manage protein levels by breaking them down in a controlled way.
Hershko studied at the Hebrew University of Jerusalem, where he became an expert in biochemistry. He focused his research on the ubiquitin-proteasome system, a cellular process that tags unwanted proteins for destruction. This is crucial for many cell functions, like cell cycle regulation, signal transduction, and ensuring correct protein synthesis.
During his career, Hershko received many notable awards for his science contributions. He won the Canada Gairdner International Award in 1999, and in 2000, he received the Albert Lasker Award for Basic Medical Research and the Alfred P. Sloan, Jr. Prize. The next year, he received the Wolf Prize in Medicine, the Louisa Gross Horwitz Prize, and the Massry Prize. In 2002, he got the E. B. Wilson Medal, and in 2012, he was awarded the Silver Medal of the President of the Senate.
His discoveries about protein degradation have significantly impacted how we understand diseases like cancer, neurodegenerative disorders, and immune system problems. The ubiquitin-proteasome pathway he helped uncover has become a key area for drug development, leading to new treatment options. Hershko's work connects basic biochemistry with practical medical uses, showing how fundamental research can lead to patient care improvements.
Hershko's scientific achievements still impact researchers around the world. His careful study of cellular processes has made him a top biochemist of his time. He received the Israel Prize in 1994, acknowledging his significant contributions to Israeli science and his role in enhancing the country's international scientific standing.
Before Fame
Born in Hungary during a time of political turmoil in Europe, Hershko's early years were shaped by the conflicts of the late 1930s and 1940s. His family's move from Hungary to Israel mirrored the experiences of many Jewish families seeking stability and opportunities in the new state.
Biochemistry was booming during Hershko's early career as a scientist. The discovery of DNA's structure in 1953 and the rise of molecular biology opened up new ways to study how cells work at a molecular level. This scientific boom laid the groundwork for Hershko's later research into how proteins are regulated and how cellular machinery functions.
Key Achievements

Did You Know?
- 01.His research on protein degradation began as an investigation into why proteins in reticulocytes (immature red blood cells) were being broken down in test tubes
- 02.The ubiquitin protein he studied is found in virtually all eukaryotic cells and is one of the most conserved proteins in biology
- 03.He shared the Nobel Prize with Aaron Ciechanover, who was once his graduate student
- 04.His work helped explain why certain cancer drugs that target the proteasome are effective in treating multiple myeloma
- 05.The name 'ubiquitin' comes from the protein's ubiquitous presence in cells, reflecting its fundamental importance
