Arf Family Gtpases

For the first time experts in the area of signalling research with a focus on the ARF family have contributed to the production of a title devoted to ARF biology. A comprehensive phylogenetic analysis of the ARF family, tables of the ARF GEFs and ARF GAPs, and more than a dozen chapters describing them in detail are provided. The impact of the ARF proteins on widely diverse aspects of cell biology and cell signalling can be clearly seen from the activities described; including membrane traffic, lipid metabolism, receptor desensitization, mouse development, microtubule dynamics, and bacterial pathogenesis. Anyone interested in understanding the complexities of cell signalling and the integration of signalling networks will benefit from this volume.

This second of two volumes discusses subfamily proteins which function in molecular and vesicular transport mechanisms inside the cell. In this volume the focus lies on the Rab, Ran and Arf subfamily members. As in Volume 1, the book is written by international renowned scientists in the field of small G-proteins. In elaborate reviews, biochemistry, structure, function and G-protein - effector interactions are described. Together with Volume 1 this book provides an comprehensive state-of-the-art work on small G-proteins (GTPases). It is written for Graduates and Professors in Biochemistry and Cell Biology interested in the mechanism and function of small G-proteins but are extremely valuable for those who want to move into the field.

In recent years, the role of cilia in the study of health, development and disease has been increasingly clear, and new discoveries have made this an exciting and important field of research. This comprehensive volume, a complement to the new three-volume treatment of cilia and flagella by King and Pazour, presents easy-to-follow protocols and detailed background information for researchers working with cilia and flagella. *Covers protocols for primary cilia across several systems and species * Both classic and state-of-the-art methods readily adaptable across model systems, and designed to last the test of time * Relevant to clinicians and scientists working in a wide range of fields

Pathogenic bacteria for human and animals have developed sophisticated weapons, termed virulence factors, to ensure their replication and persistence into their hosts. The authors in this volume show a synthesis on how the various host cellular Rho GTPases activities are manipulated by bacteria to fulfil their virulence.

The GTPase switch appears to be almost as old as life itself, and nature has adapted it to a variety of purposes. This two-volume work surveys the major classes of GTPases, including their role in ensuring accuracy during protein translation, a new look at the trimeric G-protein cycle, the molecular function of ARF in vesicle coating, the emerging role of the dynamin family in vesicle transfer, GTPases which activate GTPases during nascent protein translocation, and the many roles of ras-related proteins in growth, cytoskeletal polymerization, and vesicle transfer. 80 chapters contain much previously unpublished data and, at the rate the extended family of GTPases is growing, it is unlikely that it will again sit for a group portrait such as this. Thus, this could well become the standard reference work.

This book covers the past, present and future of the intra-cellular trafficking field, which has made a quantum leap in the last few decades. It details how the field has developed and evolved as well as examines future directions.

Rho GTPases control many aspects of cell physiology. This includes polarity, endo/exocytosis, adhesion, motility, transcriptional activation, cell cycle progression or apoptosis. In view of such pleiotropic activities, Rho-controlled signaling has proven to be of medical relevance, especially in tumorigenesis, disease-associated bone remodeling and infectiology. This book is divided into three parts. Part 1 gives an evolutionary perspective of the Rho family, its atypical members, and an overview of how Rho activity is regulated. Part 2 addresses two important aspects of multicellularity controlled by Rho-dependent pathways, namely, cell-cell interactions and mechanotransduction. It also describes how post-translational modifications control Rho activity and how this is exploited by pathogenic bacteria. Part 3 explores several examples of the variety of pathophysiological processes controlled by Rho signaling, and gives a successful example of translational research, from the inhibition of Rho activation to the development of new molecules against osteoporosis. This updated review on the biology of Rho GTPases is an essential read for molecular and cell biologists. It is also an invaluable guide to post-graduate and medical students who wish to deepen their knowledge in cell biology.
