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.

Small GTPases play a key role in many aspects of contemporary cell biology: control of cell growth and differentiation; regulation of cell adhesion and cell movement; the organization of the actin cytoskeleton; and the regulation of intracellular vesicular transport.This volume and its companions (Volumes 255, 256, 257, and the forthcoming 325) cover all biochemical and biological assays currently in use for analyzing the role of small GTPases in these aspects of cell biology at the molecular level.

This second edition volume expands on the previous edition with a discussion of new research and discoveries in the Rab field. Chapters in this book cover topics such as new information on Rab regulation and localization; interaction; function; and diseases. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and comprehensive, Rab GTPases: Methods and Protocols, Second Edition is a valuable resource for scientists working in the fields of Rab and other small GTPases, and beyond.

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.

The peroxisome is an organelle with essential roles in lipid metabolism, maintenance of reactive oxygen species homeostasis, and anaplerotic replenishment of tricarboxylic acid cycle intermediates destined for mitochondria. Peroxisomes constitute a dynamic endomembrane system. The homeostatic state of this system is upheld via two pathways for assembling and maintaining the diverse peroxisomal compartments constituting it; the relative contribution of each pathway to preserving such system may vary in different organisms and under various physiological conditions. One pathway begins with the targeting of certain peroxisomal membrane proteins to an endoplasmic reticulum template and their exit from the template via pre-peroxisomal carriers; these carriers mature into metabolically active peroxisomes containing the entire complement of membrane and matrix proteins. Another pathway operates via growth and maturation of pre-existing peroxisomal precursors that do not originate from the endoplasmic reticulum; mature peroxisomes proliferate by undergoing fission. Recent studies have uncovered new roles for the peroxisomal endomembrane system in orchestrating important developmental decisions and defining organismal longevity. This Frontiers Special Topic Issue is focused on the advances in our understanding of how evolutionarily distant organisms coordinate the formation, maturation, proliferation, maintenance, inheritance and quality control of the peroxisomal endomembrane system and how peroxisomal endomembranes communicate with other cellular compartments to orchestrate complex biological processes and various developmental programs from inside the cell.
