Book Description
Examines new research on the role of cholesterol in regulating ion channels and receptors and its effect on health Drawing together and analyzing all the latest research findings, this book explores the role of cholesterol in the regulation of ion channels and receptors, including its pathological effects. It is the first book to comprehensively describe the complex mechanisms by which cholesterol regulates two major classes of membrane proteins. Moreover, it sheds new light on how cholesterol affects essential cellular functions such as the contraction of the heart, propagation of nerve impulses, and regulation of blood pressure and kidney function. Written and edited by leading pioneers in the field, Cholesterol Regulation of Ion Channels and Receptors is divided into three parts: Part I, Cholesterol Regulation of Membrane Properties, introduces the heterogeneity of cholesterol distribution in biological membranes and the physical and biological implications of the formation of cholesterol-rich membrane domains. Part II, Cholesterol Regulation of Ion Channels, examines the mechanisms underlying cholesterol sensitivities of ion channels, including the regulation of ion channels by cholesterol as a boundary lipid. Part III, Cholesterol Regulation of Receptors, explores the latest discoveries concerning how cholesterol regulates distinct types of receptors, including G-protein coupled receptors, LDL and scavenger receptors, and innate immune system receptors. Increased levels of cholesterol represent a major health risk. Understanding cholesterol regulation of ion channels and receptors is essential for facilitating the development of new therapeutic strategies to alleviate the impact of pathological cholesterol conditions. With this book as their guide, readers have access to the most current knowledge in the field.

Book Description
In this book, renowned scientists describe the role of steroid chirality and modification of lipid membrane physical properties in the modulation of G protein-coupled receptors and ion channels. The application of commonly-used technical approaches such as mass spectrometry and nucleic magnetic resonance transfer spectroscopy for studies on cholesterol distribution and alteration of lipid bilayer characteristics is also discussed. This book offers comprehensive insights into the current understanding of cholesterol-driven modulation of protein function via mechanisms that extend beyond lipid-protein direct interactions. In the first part, the chapters introduce the reader to the use of the chemical derivatives of cholesterol as a valuable laboratory tool in the studies of cholesterol-driven modulation of protein function. In the second part, examples of cholesterol-induced changes in membrane physical characteristics are presented and discussed in light of their multifaceted contribution to the effect of cholesterol on protein function. The book will be of interest to undergraduate and graduate students as well as basic science and medical researchers with a keen interest in the biophysical properties of cholesterol and physiological consequences of cholesterol presence in biological systems.

Book Description
Knowledge of cholesterol and its interaction with protein molecules is of fundamental importance in both animal and human biology. This book contains 22 chapters, dealing in depth with structural and functional aspects of the currently known and extremely diverse unrelated families of cholesterol-binding and cholesterol transport proteins. By drawing together this range of topics the Editor has attempted to correlate this broad field of study for the first time. Technical aspects are given considerable emphasis, particularly in relation cholesterol reporter molecules and to the isolation and study of membrane cholesterol- and sphingomyelin-rich "raft" domains. Cell biological, biochemical and clinical topics are included in this book, which serve to emphasize the acknowledged and important benefits to be gained from the study of cholesterol and cholesterol-binding proteins within the biomedical sciences and the involvement of cholesterol in several clinical disorders. It is hoped that by presenting this topic in this integrated manner that an appreciation of the fact that there is much more that needs to be taken into account, studied and understood than the widely discussed "bad and good cholesterol" associated, respectively, with the low- and high-density lipoproteins, LDL and HDL.

Book Description
In this book, renowned scientists describe how cholesterol interacts with various proteins. Recent progress made in the high-resolution visualization of cholesterol-protein interactions using crystallography and cryogenic electron microscopy has substantially advanced the knowledge of critical features. These features enable specific recognition of the cholesterol molecule by proteins, a process that was built on earlier studies using binding assays, computational modeling and site-directed mutagenesis. Direct Mechanisms in Cholesterol Modulation of Protein Function offers comprehensive insights into the current understanding of cholesterol-driven modulation of protein function via direct sensing. Its nine chapters are organized into two distinct parts. In the first part, the chapters introduce the reader to the general characteristics of cholesterol binding sites in proteins. This part starts with a tour into common cholesterol recognition motifs, followed by an overview of the major classes of steroid-binding proteins. It then continues with two chapters that present a comprehensive analysis of molecular and structural characteristics of cholesterol binding sites in transmembrane and soluble protein domains. In the second part of the book, examples of cholesterol binding sites and consequences of specific cholesterol recognition for protein function are presented for G protein-coupled receptors, ion channels and cholesterol-transporting proteins. The book is valuable for undergraduate and graduate students in biochemistry and nutrition, as well as basic science and medical researchers with a keen interest in the biophysical properties of cholesterol and physiological consequences of cholesterol presence in biological systems.

Book Description
The Textbook of Ion Channels is a set of three volumes that provides a wide-ranging reference source on ion channels for students, instructors and researchers. Ion channels are mem- brane proteins that control the electrical properties of neurons and cardiac cells; medi- ate the detection and response to sensory stimuli like light, sound, odor, and taste; and regulate the response to physical stimuli like temperature and pressure. In non-excitable tissues, ion channels are instrumental for the regulation of basic salt balance that is critical for homeostasis. Ion channels are located at the surface membrane of cells, giving them the unique ability to communicate with the environment, as well as the membrane of intracellular organelles, allowing them to regulate internal homeostasis. Ion channels are fundamentally important for human health and diseases, and are important targets for pharmaceuticals in mental illness, heart disease, anesthesia, pain and other clinical appli- cations. The modern methods used in their study are powerful and diverse, ranging from single ion-channel measurement techniques to models of ion channel diseases in animals, and human clinical trials for ion channel drugs. Volume III includes coverage of key ion channel regulators and their mechanisms, the role of ion channels working in concert in selected physiological systems, and examples of ion channel mutations and dysfunction in a selection of diseases. Chapters on ion channel regulation include splice variants, calcium–calmodulin regulation, regulation by G pro- teins, and lipids. A selection of ion channels in physiological systems includes ion chan- nels of the heart, ion channels in immune cells and their role in pancreatic beta cells and regulation of insulin secretion, and the role of channels in sperm and eggs. While disease mechanisms are integrated into the chapters of Volume II, Volume III offers special consid- eration of ion channels in epilepsy, cystic fibrosis and pain syndromes. All three volumes give the reader an introduction to fundamental concepts needed to understand the mechanism of ion channels, a guide to the technical aspects of ion channel research, offer a modern guide to the properties of major ion channel families, and includecoverage of key examples of regulatory, physiological, and disease roles for ion channels.

Book Description
Volume 33 reviews the current understanding of ion channel regulation by signal transduction pathways. Ion channels are no longer viewed simply as the voltage-gated resistors of biophysicists or the ligand-gated receptors of biochemists. They have been transformed during the past 20 years into signaling proteins that regulate every aspect of cell physiology. In addition to the voltage-gated channels, which provide the ionic currents to generate and spread neuronal activity, and the calcium ions to trigger synaptic transmission, hormonal secretion, and muscle contraction, new gene families of ion channel proteins regulate cell migration, cell cycle progression, apoptosis, and gene transcription, as well as electrical excitability. Even the genome of the lowly roundworm Caenorhabditis elegans encodes almost 100 distinct genes for potassium-selective channels alone. Most of these new channel proteins are insensitive to membrane potential, yet in humans, mutations in these genes disrupt development and increase individual susceptibility to debilitating and lethal diseases.How do cells regulate the activity of these channels? How might we restore their normal function? In Ion Channel Regulation, many of the experts who pioneered these discoveries provide detailed summaries of our current understanding of the molecular mechanisms that control ion channel activity. Reviews brain functioning at the fundamental, molecular level Describes key systems that control signaling between and within cells Explains how channels are used to stimulate growth and changes to activity of the nucleus and genome
