Small GTP binding proteins and bacterial virulence

Microbes and Infection, 2000
Many bacterial toxins and bacterial enzymes modify small GTPases. Toxins exhibit different enzymatic activities on either the switch 1 or switch 2 domains of these small GTPases leading to inactivation or activation of such intracellular timer molecules.

Regulation of vesicular transport by GTP-binding proteins

Current Opinion in Nephrology and Hypertension, 1995
Intracellular 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.

Small GTP-binding proteins as compartmental markers

Seminars in Cell Biology, 1992
Each intracellular compartment involved in the biosynthetic/secretory pathway of eukaryotic cells bears at its surface at least one small GTP-binding protein. Most of them belong to a distinct branch of the p21ras superfamily, the Sec4/Ypt1/rab family. Other proteins are members of the ARF family.

The Cellular Functions of Small GTP-Binding Proteins

Science, 1990
A substantial number of novel guanine nucleotide binding regulatory proteins have been identified over the last few years but the function of many of them is largely unknown. This article will discuss a particular family of these proteins, structurally related to the Ras oncoprotein.
