Cytoplasmic complexes, called proteasomes, digest older or abnormal proteins that have been tagged with ubiquitin for destruction.

As an undergraduate at Stanford University, he presciently began his studies in the nascent field of biochemistry, working with James Murray Luck on protein turnover in the liver.
