Tropomyosin is one of the two core components of the actin filament and is involved in regulating most if not all functions of these filaments. Tropomyosin has brought together research leaders in this field to review not only what we know but also what the future holds for this field of research. All aspects of tropomyosin biology are covered from gene structure and expression to protein structure, their role in cell function and disease and finally to mechanisms of their function. The book is essential reading for anyone interested in cell structure and function. The actin architectural system is involved in the majority of cellular processes and this book explains how the tropomyosins contribute to this diversity of function. It is not only a comprehensive resource for those working in the field but is also designed to introduce the broader research community to these important molecules.
