New links between vesicle coats and Rab-mediated vesicle targeting.

Vesicle trafficking is a highly regulated process that transports proteins and other cargoes through eukaryotic cells while maintaining cellular organization and compartmental identity. In order for cargo to reach the correct destination, each step of trafficking must impart specificity. During vesicle formation, this is achieved by coat proteins, which selectively incorporate cargo into the na...

Rab proteins, connecting transport and vesicle fusion.

Small GTPases of the Rab family control timing of vesicle fusion. Fusion of two vesicles can only occur when they have been brought into close contact. Transport by microtubule- or actin-based motor proteins will facilitate this process in vivo. Ideally, transport and vesicle fusion are linked activities. Active, GTP-bound Rab proteins dock on specific compartments and are therefore perfect can...

Vesicle Trafficking: A Rab Family Profile

A new tool-kit has been developed for profiling expression and function of Rab GTPases on a genome-wide scale. Use of this tool-kit has revealed unexpectedly that at least half of Drosophila Rabs have neuronal-specific expression patterns and localize to synapses.

Sequential Coupling between CoplI and CopI Vesicle Coats in Endoplasmic Reticulum to Golgi Transport

COPI and COPII are vesicle coat complexes whose assembly is regulated by the ARF1 and Sarl GTPases, respectively. We show that COPI and COPII coat complexes are recruited separately and independently to E R (COPII), pre-Golgi (COPI, COPII), and Golgi (COPI) membranes of mammalian cells. To address their individual roles in E R to Golgi transport, we used stage specific in vitro transport assays...
