My lab is interested in deciphering the basic regulatory principles in signal transduction networks on a molecular level, focusing on growth factor receptor signaling. In particular, we study the role of scaffolding proteins and other regulators signal transduction in this pathway, using a combination of X-ray crystallography, biophysical and cellular approaches. Scaffolds, which serve as docking hubs for the signaling switches, provide specificity and higher-order control in signaling reactions. Understanding the architecture, mode of action and regulation of these processes will elucidate how cells respond to various inputs producing distinct outputs by using a limited set of molecules.
