Research Synopsis

The Kritzer lab uses peptides and peptidomimetics (peptide-like synthetic molecules) to inhibit disease-associated proteins that would be difficult or impossible to target using traditional approaches. These molecules are an exciting and rapidly expanding area of drug development because they can target protein surfaces in ways small molecules rarely do. We discover, develop and apply new classes of peptides using cross-disciplinary approaches including genetics, cell biology, organic synthesis, structural biology and biophysical chemistry. Our molecules alter critical pathways in pathogens and host cells, including virulence factors, phosphatase signaling, autophagy, and vesicle trafficking.
