Protein folding and aggregation is the process by which newly synthesized proteins fold into the specific three-dimensional structures defining their biologically active states. It has always been a major focus of research in biochemistry and has often been seen as the unsolved second part of the genetic code. In the last 10 years we have witnessed a quantum leap in the research in this exciting area. Computational methods have improved to the extent of making possible to simulate the complete folding process of small proteins and the early stages of protein aggregation. Experimental methods h.

Research indicates that most neurodegenerative diseases, systemic amyloidoses and many others, arise from the misfolding and aggregation of an underlying protein. This is the first book to discuss significant achievements in protein structure-function relationships in biochemistry, molecular biology and molecular medicine. The authors summarize recent progress in the understanding of the relationships between protein misfolding, aggregation and development of protein deposition disorders.

The second volume continues to fill the gap in protein review and protocol literature. It does this while summarizing recent achievements in the understanding of the relationships between protein misfoldings, aggregation, and development of protein deposition disorders. The focus of Part B is the molecular basis of differential disorders.

Neurofibrillary tangles (NFTs) composed of intracellular aggregates of tau protein are a key neuropathological feature of Alzheimer’s Disease (AD) and other neurodegenerative diseases, collectively termed tauopathies. The abundance of NFTs has been reported to correlate positively with the severity of cognitive impairment in AD. However, accumulating evidences derived from studies of experimental models have identified that NFTs themselves may not be neurotoxic. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. However, the exact neurotoxic tau species remain unclear. Because mature tangles seem to be non-toxic component, “tau oligomers” as the candidate of “toxic” tau have been investigated for more than one decade. In this topic, we will discuss our consensus of “tau oligomers” because the term of “tau oligomers” [e.g. dimer (disulfide bond-dependent or independent), multimer (more than dimer), granular (definition by EM or AFM) and maybe small filamentous aggregates] has been used by each researchers definition. From a biochemical point of view, tau protein has several unique characteristics such as natively unfolded conformation, thermo-stability, acid-stability, and capability of post-translational modifications. Although tau protein research has been continued for a long time, we are still missing the mechanisms of NFT formation. It is unclear how the conversion is occurred from natively unfolded protein to abnormally mis-folded protein. It remains unknown how tau protein can be formed filaments [e.g. paired helical filament (PHF), straight filament and twisted filament] in cells albeit in vitro studies confirmed tau self-assembly by several inducing factors. Researchers are still debating whether tau oligomerization is primary event rather than tau phosphorylation in the tau pathogenesis. Inhibition of either tau phosphorylation or aggregation has been investigated for the prevention of tauopathies, however, it will make an irrelevant result if we don’t know an exact target of neurotoxicity. It is a time to have a consensus of definition, terminology and methodology for the identification of “tau oligomers”.

This book provides a comprehensive overview of the biology of the endoplasmic reticulum (ER) and the associated ER proteins, it discusses their structure, function and signaling mechanisms in the cell and their role in disease. This book also offers insights into the practical aspects of research and demonstrates the use of non-mammalian models to study the structure and function of the ER. Written by leading experts in the field, the book enables readers to gain a thorough understanding of current ER biology. It is intended for scientists and clinical researchers working on the endoplasmic reticulum in all its various roles and facets in health and disease.

Since the publication of the first edition of mechanisms of protein folding in 1994, significant advances in both the technical and conceptual understanding of protein folding. This new edition has been brought up to date in content, context, and authorship and will make the subject accessibleto a wide range of scientists. The emphasis on experimental approaches has benn maintained from the first edition but this time within the explicit context of simulations and energy surfaces. There is an introductory chapter explaining the 'new' model of protein folding, which takes into account theheterogeneity of the starting state. Advances in interpreting observed kinetic data and the development of technology to observe fast folding reactions and characterize intermediate structures have accompanied this new view and are covered in detail. The term 'molten globule'is often usedincorrectly but here the significance of the term is carefully described at different satges of folding. The concept of the transition state, including the complementary approaches of molecular dynamics and protein engineering, is also discussed in detail. In vitro studies provide the molecularbasis for the thermodynamic and kinetic energy minimization of the in vivo processes of protein folding and two of the potentially rate determining reactions are disulphide bond formation and proline isomerization. It has also become increasingly apparent that chaperone proteins play a vital role inprotein folding and other reactions of proteins involoving major conformational change and the molecular details of these processes are discussed in detail in chapter 14. The final chapter describes the centreal importance of protein folding and unfolding reactions in disease and gives claerdefinition of the term 'misfolding'. Studying protein folding in vivo is full of problems and to show how these problems can be overcome in practice, three case studies of three very different types of protein have been included: the small globular protein apomyoglobin; the fibrous protein collagen;and the membrane protein haemagglutinin.

Current research suggests that neurodegenerative diseases such as Alzheimer's, Parkinson's, Huntington's, and Creutzfeldt-Jacob may be linked to disorders in protein shape referred to as protein misfolding. Continued study in this area could lead to promising advances in future treatment of these diseases. This groundbreaking text describes the latest findings regarding protein misfolding in the context of it being a marker, and perhaps a cause, in neurodegenerative diseases. Comprehensive coverage includes the diverse biochemical targets/markers for each disease, the currently limited success of drug therapies, and the cutting-edge research that could lead to more promising treatments.
