Book Description
Humans contain more than 20 Rho type GTPases. This volume not only presents a detailed phylogenetic analysis of Rho proteins, but also discusses the possible origins of the human members. Such an analysis of human Rho GTPases has not previously been attempted. The book includes an overview of how Rho GTPases become activated which is complemented by an extensive Chapter by Darerca Owen and Helen Mott who unravel the beautiful molecular details given to us by the many structural studies of Rho GTPases. The key areas currently being investigated in relation to these ubiquitous proteins are described for both in vitro and in vivo systems. These are presented in a format that ensures the reader can approach the topic with minimal background knowledge, while ultimately bringing the subject to the level of an expert. Timely and highly authoritative, this volume illuminates newer findings, particularly as they relate to Rho proteins in vertebrate biology.

Book Description
Members of the Rho family of small GTP-binding proteins (GTPases) are key signal transduction proteins that mediate signals initiated by growth factors, cytokines and cell adhesion proteins. Our knowledge about Rho GTPases has rapidly expanded over the past several years and Rho GTPases is the first book to provide a comprehensive overview of the regulation and functions of this important class of proteins. This book includes several chapters dedicated to the review of various classes of proteins that control the localization and activation state of Rho GTPases. Additional chapters discuss the wide range of biological functions that are controlled by Rho GTPases, including the organization of the actin cytoskeleton, cell proliferation and cell motility. Rho GTPases is essential reading for cell and molecular biologists, biochemists and geneticists. The critical roles of Rho family members in cancer and inflammatory diseases makes Rho GTPases also an invaluable guide for clinical investigators and pharmacologists.

Book Description
Channing Der and colleagues provide an encyclopedic overview of the Rho GTPases, providing enough detail to make any reader well-versed in the Rho field. Finally, Sofia Merajver’s laboratory provides an overview, which details the roles of the Rho proteins in cancer progression. She provides us with the history of the study of the Rho GTPases, their regulatory and effector proteins in cancer and gives us a benchmark of where the field is today. The second section of the book details the current knowledge of the Rho regu- tory proteins in cancer progression: aberrant expression and activation of these proteins leads to dysfunctional Rho signaling and a cancer phenotype. Gary Bokoch’s laboratory has provided a detailed overview of the role of Rho guanine dissociation inhibitors (GDIs) in cancer. These molecules are involved in preventing the Rho protein from associating with the inner plasma membrane and exchanging GDP for GTP, and thus becoming active. Next, Tozu Kazasa’s labo- tory has worked on the link between heterotrimeric G proteins and Rho activation via the RGS–RhoGEFs. This aspect of Rho activation is particularly interesting in that heterotrimeric G proteins and their associated G-protein-coupled receptors are attractive and attainable therapeutic targets. Dan Billadeau’s laboratory has worked extensively on the Vav RhoGEFs, which are potent oncogenes in their own right.

Book Description
In the last 10 years researchers have firmly established key roles for R- related GTPases in almost every aspect of cell biology. In the 1980s the pro- oncogene Ras itself was the focus of interest, though in the 1990s this shifted to the increasing variety of Ras-related proteins. In this new decade much yet needs to be done to establish the role for all the small GTPases now uncovered by the human genome project. In particular, these GTPases need to be und- stood in the appropriate biochemical and cellular contexts. In the process of trying to uncover the role of these versatile proteins, a variety of novel te- niques and methodologies has been developed. These now enable investi- tors to move easily within a diversity of fields ranging from structural studies to real-time in vivo analysis of a GTPase. In recognition of the need for access to key background methodologies, GTPase Protocols: The Ras Superfamily is devoted to techniques that are pr- ently widely used and that will continue to be the standard for researchers worldwide. Each chapter is aimed at supplying detailed methodologies to allow reproduction in any laboratory, while also providing the general pr- ciples on which the methods are based. Some of the techniques grouped in the first section apply broadly to small GTPases, whereas others in Part II are more applicable within each GTPase subfamily.

Book Description
In recent years remarkable progress has been accomplished with respect to our knowledge about bacterial protein toxins. This refers especially to structural aspects of protein toxins but also holds true for genetics, molecular biology and biochemical mechanisms underlying the action of toxins. This volume covers the very current and exciting aspects of up-to-date bacterial toxicology and comprehensively reviews the most important bacterial protein toxins such as the intracellular acting toxins which exhibit enzyme activity, as well as those toxins that interact with cell plasma membranes by damaging the membranes (pore formation) or stimulating cell receptors (superantigens). This is the most current reference work on these important bacterial protein toxins, which are presented from the point of view of different disciplines such as pharmacology, microbiology, cell biology and protein chemistry.

Book Description
The Ras superfamily (>150 human members) encompasses Ras GTPases involved in cell proliferation, Rho GTPases involved in regulating the cytoskeleton, Rab GTPases involved in membrane targeting/fusion and a group of GTPases including Sar1, Arf, Arl and dynamin involved in vesicle budding/fission. These GTPases act as molecular switches and their activities are controlled by a large number of regulatory molecules that affect either GTP loading (guanine nucleotide exchange factors or GEFs) or GTP hydrolysis (GTPase activating proteins or GAPs). In their active state, they interact with a continually increasing, functionally complex array of downstream effectors. Since the last Methods in Enzymology volume on this topic in 2000, Rho GTPases have continued to receive a huge amount of attention. The human genome sequence has revealed the full extent of the Rho GEF and Rho GAP families (over 80 members for each) and the challenge of identifying the molecular interactions and cellular pathways influenced by each of these regulators is a daunting prospect. This new volume, Regulators and Effectors of Small GTPases: Rho Family, describes some of the methods currently being used to examine Rho family GTPase regulation at the biochemical and cellular level. Describes the methods currently being used to examine Rho family GTPase regulation at the biochemical and cellular levels Includes new imaging techniques that revolutionize the ability to visualize GTPase activities Over 150 international contributors

Book Description
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.
