Our laboratory studies signal transduction systems controlled by heterotrimeric G proteins as well as Ras-related GTPases. The superfamily of GTPases control numerous signaling cascades based upon the regulated binding, hydrolysis, and exchange of guanine nucleotides; GTP-bound GTPases are active in downstream signaling while those bound to GDP are inactive. Mutant GTPases with abnormal GDP\/GTP cycling are implicated in numerous human diseases, including cancer. It is our desire to better understand the regulation of heterotrimeric G proteins and Ras-related GTPases at the molecular level with the ultimate goal of using this information to design therapies to correct abnormal signaling mediated by these proteins and thereby treat associated pathologies.<\/p>\n
