Molecular Aspects of the Stress Response Chaperones, Membranes and Networks [Paperback]

This book makes a novel synthesis of the molecular aspects of the stress response and long term adaptation processes with the system biology approach of biological networks. Authored by an exciting mixture of top experts and young rising stars, it provides a comprehensive summary of the field and identifies future trends.

We are extremely happy to present the reader this book containing a summary of a well-known research field, the phenomenon of cellular stress defense from two new angles: networks and membranes. The volume starts with an introduction to the concept of molecular chaperones in their original sense: R. John Ellis, the founder of the chaperone concept describes chaperones as mediators of correct assembly and/or misassembly of other macromolecular complexes. This sets the tone of the book, where later chapters give detailed examples of the richness of chaperone ac? tion by hundreds of other proteins and membrane structures. The reader will learn the role of chaperone classes such as Hsp27 or Hsp90, the action of highly organized chaperone networks in various cellular compartments such as the ER or mitochondrial/ER networks as well as the molecular details of the signaling mechanisms leading to chaperone induction during stress. Various special stress defense mechanisms against oxidative stress or dryness will also be covered. Membranes comprise a surprising mixture of stability and dynamics in the cell. Their role in the regulation of the stress response has been accepted only slowly in the field. Two chapters summarize this important aspect of the stress response showing the importance of membrane hyperstructures, lipid species composition, protein/ membrane interactions and cold adaptation.Protein Misassembly.- The Cellular Networking of Mammalian Hsp27 and Its Functions in the Control of Protein Folding, Redox State and Apoptosis.- Molecular Interaction Network of the Hsp90 Chaperone System.- Organization of the Functions and Coml#J
