Download or read book Ion Channels written by David J. Aidley and published by Cambridge University Press. This book was released on 1996-08-13 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion channels are crucial components of living cells. Situated in the cell's membranes. they allow particular ions to pass from one side of the membrane to the other. In recent years the patch clamp technique has allowed the activity of individual channels to be measured, and recombinant DNA technology has led to fascinating detail on their structure. Together, these technical advances have produced a great flowering of knowledge and understanding about the subject, itself leading to further breakthroughs in science and medicine. Ion Channels provides an introduction to this scientific endeavour. It emphasises the molecular structure of channels as determined by gene cloning technology. This knowledge illuminates discussions of the permeability and selectivity of channels, their gating and modulation, their responses to drugs and toxins and the human diseases caused when they do not function properly.
Download or read book The Structure and Function Relationship Between Guangxitoxin and the Voltage gated Potassium Channel Kv2 1 written by Drew Charles Tilley and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Proteins are the functional units of biology. They are essential in physiological processes. To achieve their functions, each protein folds into a characteristic three dimensional structure encoded by its primary amino acid sequence. Voltage-gated ion channels (VGICs) are a well-studied class of proteins which form pores in membranes permitting the conduction of ions. Voltage-gated potassium (Kv) channels are a specific subtype of VGICs in which the functional protein is tetrameric with each monomer consisting of six transmembrane (S1-S6) helices. Kv channels are all selective for potassium ions, yet are composed of many different subtypes which show sequence diversity and variation in cellular expression. With such diversity, their physiological contribution is difficult to determine without selective inhibitors of specific ion channel subtypes. Fortunately, natural sources of ion channel inhibitors have been found in venoms of animals such as tarantulas and scorpions. In this work I focused on the Kv2.1 channel and its interaction with the tarantula venom peptide Guangxitoxin (GxTX). In the subsequent chapters it will first introduce the physiological context of Kv2.1 activity. Functionally, Kv2.1 belongs to the delayed rectifier class of Kv channels showing sigmoidal activation in response to voltage and slow inactivation. Secondly; I will present electrophysiological measurements and chemical modification of GxTX to show the functional state of Kv2.1 modulates toxin affinity and binding kinetics. Thirdly, I will present a study using homology modeling to develop structural hypotheses of complexes of GxTX binding to the channel. Lastly, I will propose a functional mechanism for how Kv2.1 activity is modulated when GxTX is bound.
Download or read book Ion Channels and Disease written by Frances M. Ashcroft and published by Academic Press. This book was released on 1999-10-20 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion channels are membrane proteins that act as gated pathways for the movement of ions across cell membranes. They play essential roles in the physiology of all cells. In recent years, an ever-increasing number of human and animal diseases have been found to result from defects in ion channel function. Most of these diseases arise from mutations in the genes encoding ion channel proteins, and they are now referred to as the channelopathies. Ion Channels and Disease provides an informative and up-to-date account of our present understanding of ion channels and the molecular basis of ion channel diseases. It includes a basic introduction to the relevant aspects of molecular biology and biophysics and a brief description of the principal methods used to study channelopathies. For each channel, the relationship between its molecular structure and its functional properties is discussed and ways in which genetic mutations produce the disease phenotype are considered. This book is intended for research workers and clinicians, as well as graduates and advanced undergraduates. The text is clear and lively and assumes little knowledge, yet it takes the reader to frontiers of what is currently known about this most exciting and medically important area of physiology. Introduces the relevant aspects of molecular biology and biophysics Describes the principal methods used to study channelopathies Considers single classes of ion channels with summaries of the physiological role, subunit composition, molecular structure and chromosomal location, plus the relationship between channel structure and function Looks at those diseases associated with defective channel structures and regulation, including mutations affecting channel function and to what extent this change in channel function can account for the clinical phenotype
Download or read book Calcium Entry Channels in Non Excitable Cells written by Juliusz Ashot Kozak and published by CRC Press. This book was released on 2017-07-14 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calcium Entry Channels in Non-Excitable Cells focuses on methods of investigating the structure and function of non-voltage gated calcium channels. Each chapter presents important discoveries in calcium entry pathways, specifically dealing with the molecular identification of store-operated calcium channels which were reviewed by earlier volumes in the Methods in Signal Transduction series. Crystallographic and pharmacological approaches to the study of calcium channels of epithelial cells are also discussed. Calcium ion is a messenger in most cell types. Whereas voltage gated calcium channels have been studied extensively, the non-voltage gated calcium entry channel genes have only been identified relatively recently. The book will fill this important niche.
Download or read book Voltage Gated Sodium Channels written by Peter C. Ruben and published by Springer Science & Business Media. This book was released on 2014-04-15 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of techniques to study ion channels have been developed since the electrical basis of excitability was first discovered. Ion channel biophysicists have at their disposal a rich and ever-growing array of instruments and reagents to explore the biophysical and structural basis of sodium channel behavior. Armed with these tools, researchers have made increasingly dramatic discoveries about sodium channels, culminating most recently in crystal structures of voltage-gated sodium channels from bacteria. These structures, along with those from other channels, give unprecedented insight into the structural basis of sodium channel function. This volume of the Handbook of Experimental Pharmacology will explore sodium channels from the perspectives of their biophysical behavior, their structure, the drugs and toxins with which they are known to interact, acquired and inherited diseases that affect sodium channels and the techniques with which their biophysical and structural properties are studied.

Download or read book Encyclopedia of Metalloproteins written by Robert H. Kretsinger and published by Springer. This book was released on 2013-05-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In biochemistry, a metalloprotein is a generic term for a protein that contains a metal cofactor. The metal may be an isolated ion or may be coordinated with a nonprotein organic compound, such as the porphyrin found in hemoproteins. In some cases, the metal is co-coordinated with a side chain of the protein and an inorganic nonmetallic ion. This kind of protein-metal-nonmetal structure is seen in iron-sulfur clusters Metalloproteins deals with all aspects related to the intracellular and extracellular metal-binding proteins, including their structures, properties and functions. The biological roles of metal cations and metal-binding proteins are endless. They are involved in all crucial cellular activities. Many pathological conditions are related to the problematic metal metabolism. Research in metalloprotein-related topics is therefore rapidly growing, and different aspects of metal-binding proteins progressively enter curricula at Universities and even at the High School level on occasion. However, no key resource providing basic, but comprehensible knowledge on this rapidly expanding field exists. The Encyclopedia of Metalloproteins aims to bridge this gap, and will attempt to cover various aspects of metalloprotein/metalloproteomics and will deal with the different issues related to the intracellular and extracellular metal-binding proteins, including their structures, properties and functions. The goal is to cover exhaustively all catalytically and biologically crucial metal ions and to find at least one interacting protein for other metal ions. The Encyclopedia of Metalloproteins will provide a key resource for advanced undergraduate and graduate students, researchers, instructors, and professors interested in protein science, biochemistry, cell biology, and genetics.
Download or read book Scorpion Venoms written by P. Gopalakrishnakone and published by Springer. This book was released on 2021-01-14 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the field of Toxinology has expanded substantially. On the one hand it studies venomous animals, plants and micro organisms in detail to understand their mode of action on targets. While on the other, it explores the biochemical composition, genomics and proteomics of toxins and venoms to understand their three interaction with life forms (especially humans), development of antidotes and exploring their pharmacological potential. Therefore, Toxinology has deep linkages with biochemistry, molecular biology, anatomy and pharmacology. In addition, there is a fast developing applied subfield, clinical toxinology, which deals with understanding and managing medical effects of toxins on human body. Given the huge impact of toxin-based deaths globally, and the potential of venom in generation of drugs for so-far incurable diseases (for example, Diabetes, Chronic Pain), the continued research and growth of the field is imminent. This has led to the growth of research in the area and the consequent scholarly output by way of publications in journals and books. Despite this ever growing body of literature within biomedical sciences, there is still no all-inclusive reference work available that collects all of the important biochemical, biomedical and clinical insights relating to Toxinology. The Handbook of Toxinology aims to address this gap and cover the field of Toxinology comprehensively.
