Research Description
We are interested in the stereochemical details of the intermolecular interactions in signal transduction pathways.

1. Ligand induced activation of receptor tyrosine kinases (RTKs). Activation of RTKs lead to a host of downstream signaling events that result in a variety of different cellular responses, including stimulated growth. Inappropriate receptor activation can lead to cancer and understanding how these receptors function is of significant biomedical importance. Recent advances have led to the proposal of a novel mechanism for activation of one RTK that we study, the epidermal growth factor (EGF) receptor. We are investigating the implications of this model for activation and inactivation this and other RTKs.

2. Protein-protein interactions in intracellular signaling. It is clear that formation of large multimolecular assemblies plays a key role in controlling intracellular signaling, trafficking and other processes. We are using a variety of biophysical techniques to study such assembly formation in vitro, and X-ray crystallography to determine the structures of key complexes.
