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.

Book excerpt: This book presents the latest findings in the field of research of mechanosensitivity and mechanotransduction in different cells and tissues. Mechanosensitivity and mechanotransduction of the heart and vascular cells, in the lung, in bone and joint tissues, in sensor systems and in blood cells are described in detail. This Volume focuses on molecular mechanisms of mechanosensitivity and mechanotransduction via cytoskeleton. Integrin-mediated mechanotransduction, the role of actin cytoskeleton and the role of other cytoskeletal elements are discussed. It contains a detailed description of several stretch-induced signaling cascades with multiple levels of crosstalk between different pathways. It contains a description of the role of nitric oxide in regulation of cardiac activity and in regulation of mechanically gated channels in the heart. In the heart mechanical signals are propagated into the intracellular space primarily via integrin-linked complexes, and are subsequently transmitted from cell to cell via paracrine signaling. Biochemical signals derived from mechanical stimuli activate both acute phosphorylation of signaling cascades, such as in the PI3K, FAK, and ILK pathways, and long-term morphological modii cations via intracellular cytoskeletal reorganization and extracellular matrix remodelling. Cellular and molecular effects of mechanical stretch on vascular cells are also discussed. This Volume highlights the role of mechanotransduction in the lung, in bone and joint tissues. For the first time mechanosensitivity and mechanotransduction in blood cells are discussed. It contains new insights into mechanosensitive K+ channels functioning in mouse B lymphocytes. This book is a unique collection of reviews outlining current knowledge and future developments in this rapidly growing field. Currently, investigations of the molecular mechanisms of mechanosensitivity and mechanotransduction are focused on several issues. The majority of studies investigate intracellular signaling pathways. Knowledge of the mechanisms which underlie these processes is necessary for understanding of the normal functioning of different organs and tissues and allows to predict changes, which arise due to alterations of their environment. Possibly such knowledge will allow the development of new methods of artificial intervention and therapies. This book brings up the problem closer to the experts in related medical and biological sciences as well as practicing doctors besides just presenting the latest achievements in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Ion channel drug discovery is a rapidly evolving field fuelled by recent, but significant, advances in our understanding of ion channel function combined with enabling technologies such as automated electrophysiology. The resurgent interest in this target class by both pharmaceutical and academic scientists was clearly highlighted by the over-subscribed RSC/BPS 'Ion Channels as Therapeutic Targets' symposium in February 2009. This book builds on the platform created by that meeting, covering themes including advances in screening technology, ion channel structure and modelling and up-to-date case histories of the discovery of modulators of a range of channels, both voltage-gated and non-voltage-gated channels. The editors have built an extensive network of contacts in the field through their first-hand scientific experience, collaborations and conference participation and the organisation of the meeting at Novartis, Horsham, increased the network enabling the editors to draw on the experience of eminent researchers in the field. Interest and investment in ion channel modulation in both industrial and academic settings continues to grow as new therapeutic opportunities are identified and realised for ion channel modulation. This book provides a reference text by covering a combination of recent advances in the field, from technological and medicinal chemistry perspectives, as well as providing an introduction to the new 'ion channel drug discoverer'. The book has contributions from highly respected academic researchers, industrial researchers at the cutting edge of drug discovery and experts in enabling technology. This combination provides a complete picture of the field of interest to a wide range of readers.

Available in PDF, EPUB and Kindle. Book excerpt: Since the pioneering discoveries of Hodgkin, Huxley, and Katz, it has been clear that specific ion conductance pathways underlie electrical act- ity. Over the ensuing 50 years, there has been ever increasing, and occasi- ally explosive, changes in the scope of efforts to understand ion channel behavior. The introduction of patch clamp technology by Erwin Neher and Bert Sakmann about 20 years ago led to the realization of the great variety of novel ion channel species, and the subsequent revolution in cl- ing has revealed an even greater diversity of the underlying molecular entities. Today, advances in the study of ion channel structure and function c- tinue at a high pace, from angstrom resolution imaging of crystallized ch- nels to their genetic manipulations in animals. In this regard, the field is a balanced one that inquires not only what ion channel entities are there, or how they operate, but also where are these molecular electronic switches? However, this balance is not particularly well presented to the general sci- tific audience or to specialists in the field. There are plenty of wonderful and useful books and monographs, as well as conferences and meetings on v- tually every aspect of ion channel structure and function. However, we are unaware that the channel localization theme has been considered in a u- fied forum.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In the past decade neuronal plasticity has become a major theme of modern neurobiology, from cellular and molecular mechanisms of synapse formation in worms and insects to behavioural recovery from strokes in elderly humans. For this reason the focus of interest in the present volume of Progress in Brain Research is on the topic of neuroplasticity in mature organisms, including humans. Contributions range from neurogenesis and synaptic plasticity in the adult primate brain, to neural mechanisms of learning and memory, and the influence of environmental factors and aging on the functional potential of the central nervous system. Several contributions focus on recent developments in neural regeneration and brain repair, providing challenging evidence that the use of stem cell neurotherapy may be beneficial to humans suffering from various neurological and psychiatric diseases. This volume integrates new information on the cellular and molecular mechanisms of neuroplasticity and highlights challenging future questions in this exciting and topical area of neuroscience.
