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
G proteins are the key regulators for a wide range of cellular processes in animals and plants. In comparison to animals and yeast, plants have a single Rho-GTPase subfamily called Rho-like GTPases (ROPs). The ROP family of monomeric GTPases has emerged as a versatile and key regulator in plant signal transduction processes. During the past few years’ studies on plant RHO-type (ROP) GTPase have generated new insights into their role in diverse processes ranging from cytoskeletal organization, polar growth, development to stress and hormonal responses. Studies have shown that plants have evolved specific regulators and effector molecules. ROP GTPases possess the ability to interact with these multiple regulator and effector molecules that ultimately determines their signaling specificity. Recently, genome wide studies in plants have shown that the Arabidopsis genome encodes 93, and rice has nearly 85 small GTPase homologs. And we have been able to identify four new homologs in the rice genome. Here, we focus on the complete phylogenetic, domain, structural and expression analysis during stress and various developmental processes of small GTPases in plants. The comparison of gene expression patterns of the individual members of the GTPase family may help to reveal potential plant specific signaling mechanisms and their relevance. Also, we are summarizing the role of currently known ROP GTPases and their interacting proteins with brief description, simultaneously, comparing their expression pattern based on microarray data. Overall, we will be discussing the functional genomic perspective of plant Rho like GTPases and their role in regulating several physiological processes such as stress, hormonal, pollen tube, root hair-growth and other developmental responses.

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
This third volume in the trio covering G proteins, features integrated approaches to studying G proteins. Methods pertaining to signaling mechanisms are presented, including theoretical and modeling approaches, biochemistry and molecular biology, and cell biology and physiology. The techniques for studying the structure and function of G proteins are important not only to those with specific research interests in them, but also endocrinologists and pharmacologists conducting research on signaling mechanisms that are increasingly understood to interact with G proteins.
