Research description

Our work focuses on the relationship between structure and function in small G proteins and their effectors and regulators. These proteins control many signal transmission pathways that can become deregulated in cancer and other diseases. We focus or efforts on the Rho family small G proteins and the Ral GTPases, which are members of the Ras family. We employ a multidisciplinary approach utilizing structural biology (primarily NMR), biophysics, biochemistry and cell biology to generate data on the interactions the small G proteins undergo. These data can then be employed to drive rational drug design targeted at these protein-protein complexes.
