title: Small GTPases take the stage.
abstract: Small GTPases are molecular switches that have been adopted to control many eukaryotic cell functions. Starting with the study of the protooncogene Ras in the early 1980s, detailed pathways have been uncovered upstream and downstream of Ras-related GTP binding proteins. Nonetheless, novel members have been discovered at a pace that has outstripped cell biologists, and thus much remains to be established regarding newer family members. Undiscovered functions are still being uncovered for "established" small GTPases such as Ras, Rho, and Ran. The topics covered at this meeting indeed demonstrate that Ras proteins are at the heart of cellular dynamics.
