Summary

We are interested in understanding molecular mechanisms in cell signaling, with particular focus on enzymes that phosphorylate and dephosphorylate tyrosine residues on proteins as a means of relaying information within cells. These enzymes, known as protein tyrosine kinases and protein tyrosine phosphatases, constitute two large families of roughly 100 proteins that play crucial roles in normal physiology and are often dysregulated in diseases such as cancers and immunological disorders. As a result, these enzymes are important drug targets.

We integrate chemical approaches with high-throughput biochemical assays, biophysical methods, and cell biology to pinpoint (1) how individual members of these enzyme families have specialized to mediate signal transduction with fidelity, (2) how the dysregulation of phosphotyrosine signaling leads to disease states, and (3) how we might exploit this information to guide the development of novel therapies.
