Why highly expressed proteins evolve slowly

Abstract
The tempo and mode of protein evolution have been central questions in biology. Genomic data have shown a strong influence of the expression level of a protein on its rate of sequence evolution, or the E-R anticorrelation, but the underlying cause is unclear. In this talk, I discuss two hypotheses, protein misfolding avoidance and protein misinteraction avoidance, that potentially explain the E-R anticorrelation. The findings suggest a pivotal role of the biophysics of protein stability and interaction in constraining and channeling protein evolution.
