The importance of protein folding has been recognized for many years. It is the underlying etiology in a large number of human diseases and it appears to be a novel method for cellular regulation of the expression of newly translated proteins. These volumes (Parts A & B) address this important topic. As a volume in Progress in Nucleic Acid Research and Molecular Biology, this book provides the latest information on the expanding research being conducted on protein folding. *Follow the new editor-in-chief, P. Michael Conn, as he introduces this first thematic volume in the series – an in-depth aid to researchers who are looking for the best techniques and tools for understanding the complexities of protein folding *Understand the advantages of protein folding over other therapeutic approaches and see how protein folding plays a critical role in the development of diseases such as Alzheimer’s and diabetes *Decipher the rules of protein folding through compelling and timely reviews combined with chapters written by international authors in engineering, biochemistry, physics and computer science
