A NATO Advanced Study Institute on "Membrane Receptors, Dynamics and Energetics" was held in order to consider recent developments in membrane receptor research. Presentations and discussions focussed on signal transduction mechanisms (e.g. 2 G-proteins, transducin, Ca +) and on the structure and func tion of some selected receptors (i.e. low density lipoprotein receptor, acetylcholine receptor, growth factor receptors, toxin receptors). These topics were put in the larger con text of current knowledge on the structure and function of membranes; connections between different fields of research were established by in-depth discussions of energy transduc tion and transport mechanisms. Specialized membrane systems were discussed including chloroplasts and chromaffin granules. Functional relationships with specific lipids (e.g. phospho inositides, lipid A) were major topics of discussion. This book presents the content of the major lectures and a selection of most relevant posters presented during the course of the Institute. This book is intended to make the proceedings of the Institute accessible to a larger audience and to offer a comprehensive account of those topics of re ceptor, membrane and bioenergetics research that were at the center of interest during our stay on the Island of Spetsai from August 17 to 30, 1986.

Free energy constitutes the most important thermodynamic quantity to understand how chemical species recognize each other, associate or react. Examples of problems in which knowledge of the underlying free energy behaviour is required, include conformational equilibria and molecular association, partitioning between immiscible liquids, receptor-drug interaction, protein-protein and protein-DNA association, and protein stability. This volume sets out to present a coherent and comprehensive account of the concepts that underlie different approaches devised for the determination of free energies. The reader will gain the necessary insight into the theoretical and computational foundations of the subject and will be presented with relevant applications from molecular-level modelling and simulations of chemical and biological systems. Both formally accurate and approximate methods are covered using both classical and quantum mechanical descriptions. A central theme of the book is that the wide variety of free energy calculation techniques available today can be understood as different implementations of a few basic principles. The book is aimed at a broad readership of graduate students and researchers having a background in chemistry, physics, engineering and physical biology.

A NATO Advanced study Institute on "Receptors, Membrane Trans port and Signal Transduction", was held on the Island of Spet sai, Greece, from August 16-27, 1988, in order to consider re cent developments in membrane receptor research, membrane trans port and signal transduction mechanisms. These topics were put in the larger context of current knowledge on the structure and function of membranes; connections between different fields of research were established by in-depth dis cussions of energy transduction and transport mechanisms. The general principles of regulation by signal transduction and protein phosphorylation/dephosphorylation were presented in the context of specific cellular processes. Discussions included al so the role of protein tyrosine kinases which are structurally related to oncogene products and, therefore, implicated in va rious aspects of cell development and transformation. This book presents the content of the major lectures and a se lection of the most relevant posters presented during the course of the Institute. The book is intended to make the proceedings of the Institute accessible to a larger audience and to offer a comprehensive account of those topics on receptors, membrane transport and signal transduction that were discussed extensive ly during the course of the Institute.

Allosteric Modulation of G Protein-Coupled Receptors reviews fundamental information on G protein-coupled receptors (GPCRs) and allosteric modulation, presenting original research in the area and collectively providing a comprehensive description of key issues in GPCR allosteric modulation. The book provides background on core concepts of molecular pharmacology while also introducing the most important advances and studies in the area. It also discusses key methodologies. This is an essential book for researchers and advanced students engaged in pharmacology, toxicology and pharmaceutical sciences training and research. Many of the GPCR-targeted drugs released in the past decade have specifically worked via allosteric mechanisms. Unlike direct orthosteric-acting compounds that occupy a similar receptor site to that of endogenous ligands, allosteric modulators alter GPCR-dependent signaling at a site apart from the endogenous ligand. Recent methodological and analytical advances have greatly improved our ability to understand the signaling mechanisms of GPCRs. We now know that allostery is a common regulatory mechanism for all GPCRs and not – as we once believed – unique to a few receptor subfamilies. - Introduces background on core concepts of molecular pharmacology, including statistical analyses, non-linear regression, complex models and GPCR-dependent signal transduction as they relate to allosteric modulation - Discusses critical advances and landmark studies, including discoveries in the area of GPCR allosteric modulation, which are reviewed for their importance in positive and negative regulation, protein-protein interactions, and small molecule drug discovery - Includes key methodologies used to study allosteric modulation at the in silico, in vitro, and in vivo levels of drug discovery and characterization

This book mainly focuses on key aspects of biomembranes that have emerged over the past 15 years. It covers static and dynamic descriptions, as well as modeling for membrane organization and shape at the local and global (at the cell level) scale. It also discusses several new developments in non-equilibrium aspects that have not yet been covered elsewhere. Biological membranes are the seat of interactions between cells and the rest of the world, and internally, they are at the core of complex dynamic reorganizations and chemical reactions. Despite the long tradition of membrane research in biophysics, the physics of cell membranes as well as of biomimetic or synthetic membranes is a rapidly developing field. Though successful books have already been published on this topic over the past decades, none include the most recent advances. Additionally, in this domain, the traditional distinction between biological and physical approaches tends to blur. This book gathers the most recent advances in this area, and will benefit biologists and physicists alike.

This volume brings together information on membrane organization and dynamics from a variety of spectroscopic, microscopic and simulation approaches, spanning a broad range of time scales. The implication of such dynamic information on membrane function in health and disease is a topic of contemporary interest. The chapters cover various aspects of membrane lipid and protein dynamics, explored using a battery of experimental and theoretical approaches. The synthesis of information and knowledge gained by utilizing multiple approaches will provide the reader with a comprehensive understanding of the underlying membrane dynamics and function, which will help to develop robust dynamic models for the understanding of membrane function in healthy and diseased states. In the last few years, crystal structures of an impressive number of membrane proteins have been reported, thanks to tremendous advances in membrane protein crystallization techniques. Some of these recently solved structures belong to the G protein-coupled receptor (GPCR) family, which are particularly difficult to crystallize due to their intrinsic flexibility. Nonetheless, these static structures do not provide the necessary information to understand the function of membrane proteins in the complex membrane milieu. This volume will address the dynamic nature of membrane proteins within the membrane and will provide the reader with an up-to date overview of the theory and practical approaches that can be used. This volume will be invaluable to researchers working in a wide range of scientific areas, from biochemistry and molecular biology to biophysics and protein science. Students of these fields will also find this volume very useful. This book will also be of great use to those who are interested in the dynamic nature of biological processes.
