We have continued our studies of Rab proteins and their role in intracellular vesicular transport and have also dealt with some more general aspects of GTPases, in particular with respect to development of methods to modulate their function and to identify important partner molecules. Several of the studies of the last few years have been directed at understanding the mechanism of targeting of Rab proteins to specific membranes.
