Book Description
An introduction to the principles of membrane transport: How molecules and ions move across the cell membrane by simple diffusion and by making use of specialized membrane components (channels, carriers, and pumps). The text emphasizes the quantitative aspects of such movement and its interpretation in terms of transport kinetics. Molecular studies of channels, carriers, and pumps are described in detail as well as structural principles and the fundamental similarities between the various transporters and their evolutionary interrelationships. The regulation of transporters and their role in health and disease are also considered. Provides an introduction to the properties of transport proteins: channels, carriers, and pumps Presents up-to-date information on the structure of transport proteins and on their function and regulation Includes introductions to transport kinetics and to the cloning of genes that code transport proteins Furnishes a link between the experimental basis of the subject and theoretical model building

Book Description
Transport and Diffusion across Cell Membranes is a comprehensive treatment of the transport and diffusion of molecules and ions across cell membranes. This book shows that the same kinetic equations (with appropriate modification) can describe all the specialized membrane transport systems: the pores, the carriers, and the two classes of pumps. The kinetic formalism is developed step by step and the features that make a system effective in carrying out its biological role are highlighted. This book is organized into six chapters and begins with an introduction to the structure and dynamics of cell membranes, followed by a discussion on how the membrane acts as a barrier to the transmembrane diffusion of molecules and ions. The following chapters focus on the role of the membrane's protein components in facilitating transmembrane diffusion of specific molecules and ions, measurements of diffusion through pores and the kinetics of diffusion, and the structure of such pores and their biological regulation. This book methodically introduces the reader to the carriers of cell membranes, the kinetics of facilitated diffusion, and cotransport systems. The primary active transport systems are considered, emphasizing the pumping of an ion (sodium, potassium, calcium, or proton) against its electrochemical gradient during the coupled progress of a chemical reaction while a conformational change of the pump enzyme takes place. This book is of interest to advanced undergraduate students, as well as to graduate students and researchers in biochemistry, physiology, pharmacology, and biophysics.

Book Description
This new, fully revised and expanded edition of Ionic Channels of Excitable Membranes includes new chapters on fast chemical synapses, modulation through G protein coupled receptors and second messenger systems, molecules cloning, site directed mutagenesis, and cell biology. It begins with the classical biophysical work of Hodgkin and Huxley and then weaves a description of the known ionic channels together with their biological functions. The book continues by developing the physical and molecular principles needed for explaining permeation, gating, pharmacological modification, and molecular diversity, and ends with a discussion of channel evolution. Ionic Channels of Excitable Membranes is written to be accessible and interesting to biological and physical scientists of all kinds.

Book Description
Today's science tells us that our bodies are filled with molecular machinery that orchestrates all sorts of life processes. When we think, microscopic "channels" open and close in our brain cell membranes; when we run, tiny "motors" spin in our muscle cell membranes; and when we see, light operates "molecular switches" in our eyes and nerves. A molecular-mechanical vision of life has become commonplace in both the halls of philosophy and the offices of drug companies, where researchers are developing “proton pump inhibitors” or medicines similar to Prozac. Membranes to Molecular Machines explores just how late twentieth-century science came to think of our cells and bodies this way. This story is told through the lens of membrane research, an unwritten history at the crossroads of molecular biology, biochemistry, physiology, and the neurosciences, that directly feeds into today's synthetic biology as well as nano- and biotechnology. Mathias Grote shows how these sciences not only have made us think differently about life, they have, by reworking what membranes and proteins represent in laboratories, allowed us to manipulate life as "active matter" in new ways. Covering the science of biological membranes in the United States and Europe from the mid-1960s to the 1990s, this book connects that history to contemporary work with optogenetics, a method for stimulating individual neurons using light, and will enlighten and provoke anyone interested in the intersection of chemical research and the life sciences—from practitioner to historian to philosopher.

Book Description
As opposed to other books on the topic, this volume is unique in also covering emerging transporter targets. Following a general introduction to the importance of targeting transporter proteins with drugs, the book systematically presents individual transporter classes and explains their pharmacology and physiology. The text covers all transporter families with known or suspected importance as drug targets, including neurotransmitter transporters, ABC transporters, glucose transporters and organic ion transporters. The final part discusses recent advances in structural studies of transport proteins, assay methods for transport activity, and the systems biology of transporters and their regulation. With its focus on drug development issues, this authoritative overview is required reading for researchers in industry and academia targeting transport proteins for the treatment of disease.
