Protein Quality Control at Cellular Membranes
Our lab focuses on the mechanisms that cells use to recognize and dispose of misfolded proteins within their organelles. These processes are remarkably conserved among eukaryotes and we use Saccharomyces cerevisiae as a model system because of its simplicity relative to "higher" eukaryotes.Selected Publications
