Protein-protein interactions are involved in muscle contraction and signal transduction. This book describes how synthetic peptides may be used, much like antibodies, both as specific inhibitors and as molecular probes to explore the cognitive interfaces between interacting proteins and their functional significance. This offers the prospect of very selective intervention in cellular mechanisms. These timely contributions by several experts will appeal to the researchers in muscle physiology, cardiovascular pharmacology and cell biology who are interested in this new approach.

Recent years have witnessed an explosion of knowledge lea- ding to a molecular understanding of the mechanisms of ac- tion of calcium on excitation and contraction coupling and its role in the regulation of contractility. This book highlights the most recent progress as well as providing a historial perspective of the field. It presents a concise and comprehensive overview of our current knowledge regar- ding calcium channels and regulatory proteins as well as in- tracellular calcium handling and the mechanisms underlying the activation of contractile proteins. It also describes how these...
