Regulation of vesicular transport by GTP-binding proteins
Current Opinion in Nephrology and Hypertension, 1995Intracellular protein trafficking occurs in a series of transport vesicles. Vesicle trafficking is regulated both by heterotrimeric and monomeric GTP-binding proteins (G proteins). Recent studies have explored effector systems used by heterotrimeric G proteins and by monomeric ADP-ribosylation factor G proteins for regulation of vesicle budding.

Activation of Heterotrimeric GTP-Binding Proteins
1999Guanosine triphosphate- (GTP-) binding proteins constitute a supergene family of proteins that utilize GTP binding and hydrolysis as a chemical switch. These proteins are activated by exchanging bound guanosine diphosphate (GDP) with GTP and are subsequently inactivated by hydrolyzing bound GTP to GDP.1–3 Hence, by shuttling between an inactive, GDP ...

Small GTP-binding proteins in vesicular transport
Trends in Biochemical Sciences, 1990Recent recognition of the abundance of small GTP-binding proteins in eukaryotic cells has sparked off a search for the possible function of these proteins. Evidence is accumulating that SAR1, ARF, SEC4 and YPT1 in yeast and the rab and arf family in mammalian cells play a central role in the regulation of vesicle transport and organelle function.
