摘要
The cycle of nucleotide exchange and hydrolysis by a small GTP-binding protein, ADP-ribosylation factor (ARF), helps to provide vectoriality to vesicle transport. Coat assembly is triggered when ARF binds GTP, initiating transport vesicle budding, and coat disassembly is triggered when ARF hydrolyzes GTP, allowing the uncoated vesicle to fuse.
