title: GTP-binding proteins in intracellular transport.
abstract: One of the most exciting recent discoveries in the area of intracellular protein transport is the finding that many organelles involved in exocytic and endocytic membrane traffic have one or more Ras-like GTP-binding proteins on their cytoplasmic face that are specific for each membranous compartment. These proteins are attractive candidates for regulators of transport vesicle formation and the accurate delivery of transport vesicles to their correct targets.
