Biography

Alexander Varshavsky is recognized among Jewish contributors to Science & Medicine — Biologist who discovered the ubiquitin system's N-end rule governing protein lifespan.

How & why

Varshavsky, a Jewish biologist born in Moscow who emigrated from the Soviet Union in 1977, discovered the biological functions of the ubiquitin system, showing how cells tag proteins for controlled destruction. His 'N-end rule' revealed that a protein's lifespan is encoded by its first amino acid. Working at MIT and Caltech, his findings underlie modern understanding of protein regulation and disease.
