To carry out biological functions, a typical protein must fold into a complex structure encoded by its amino-acid sequence. Alterations of that sequence often cause misfolding, disrupting function and also creating toxic, aggregation-prone molecules.

Protein misfolding causes major human neurodegenerative diseases, shapes quality control mechanisms inside the cell, and appears to govern how rapidly protein-coding genes accumulate sequence changes over evolutionary time. Yet strikingly little is known about the major causes, amounts, or consequences of protein misfolding. Key open questions include: What are the dominant causes of protein misfolding in normal and disease-afflicted cells? What fraction of newly synthesized proteins misfold, and why? What is the error rate of protein synthesis? Why are misfolded proteins toxic?

We seek answers to these questions, taking an integrated biochemical, genetic, and evolutionary approach.

Congratulations to Dr. Kerry Samerotte, winner of the 2011 Walter M. Fitch Award.
