Prenylation of RabGTPases, their delivery to membranes and Rab recycling -- Rab proteins and the organization of organelle membrane domains -- Effectors of Rab GTPases: Rab binding specificity and their role in coordination of Rab function and localization -- A Rab effector called the exocyst and related vesicle tether complexes -- RabGEFs and GAPs – the enigma variations -- Ran in Nucleocytoplasmic Transport -- Ran in Mitosis -- Arf proteins and their regulators: at the interface between membrane lipids and the protein trafficking machinery -- Small G Proteins: Arf family GTPases in vesicular transport -- ARF-LIKE (ARL) Proteins -- GTPase-Activating Proteins for the Arf-family Small GTPases: not only for the termination -- Rag GTPases.

This second of two volumes discusses subfamily proteins involved in nucleo-cytoplasmic and vesicular transport mechanisms inside the cell. In this volume, the focus lies on the Rab, Ran and Arf subfamily members. Like Volume 1, the book was written by internationally renowned scientists in the field of small G-proteins. The biochemistry, structure, function and G-protein/effector interactions are described in detailed reviews. Together with Volume 1, this book provides a comprehensive and state-of-the-art work on small G-proteins (GTPases). It was written for graduates and professors in biochemistry and cell biology interested in the mechanism and function of small G-proteins, but also offers an extremely valuable resource for those readers who are new to the field.
