The Three Functional States of Proteins explores how structured proteins, intrinsically disordered proteins, and phase separated proteins contribute to the complexity of cellular life, and offers insights into their roles in both health and disease. It discusses the latest research findings and highlight groundbreaking discoveries and innovative methodologies used to study these protein states.Traditionally, the different states of proteins have been defined based on their structures and functions. However, it is becoming increasingly clear that these criteria alone may not be sufficient to capture the complex and multifaceted properties of these molecules. Definitions based on thermodynamics and kinetics are now recognized as potentially more appropriate for comprehensively understanding protein states. Emerging evidence indicates that under physiological conditions, a majority of proteins possess the capability to exist in and transition between the native, droplet, and amyloid states. These distinct states play crucial roles in various cellular functions, influenced significantly by their physicochemical and structural properties. The book also considers the interactions among these states and discusses how their internal organization as individual molecules, as well as their collective organization as molecular assemblies are stabilized. Furthermore, it examines the processes by which these states are formed and the cellular functions associated with each specific state. - The book serves as an introduction to a unique volume that provides comprehensive coverage of these three functional states of proteins - The chapters are written by leading global scientists who are actively engaged in research on these specific protein states - It presents a broad picture of the current, emerging, and evolving research on these protein states - Given that this book comprehensively addresses both foundational concepts and recent advancements in the field, it will appeal a broad spectrum of readers from various academic disciplines

In this monograph, the importance of fluctuations for biological reactions is discussed from various points of view. Understanding the biological reactions at the molecular level is one of the major targets in many scientific fields, including not only basic biology but also physics, physical chemistry, and medical science. One of the key factors in the process is “fluctuation”. Thermal energy causes biological molecules to be in constant fluctuation even while they are carrying out their biological functions. How do biological systems overcome the thermal fluctuations to realize the physiologically relevant reactions? Scientists in a number of fields—physics, chemistry, pharmacology, medicine, and others—have contributed chapters that elucidate the nature of the fluctuations and the relationship between fluctuations and biological functions. The fluctuations discussed in this volume are detected by the transient grating method, nuclear magnetic resonance, X-ray diffraction and scattering, and computer simulation, among other methods. The book presents various results of the studies of fluctuations in biological processes that were obtained with these methods by the leading scientists in their fields.

The word revolution has a number of definitions (The American Heritage Dictionary, 2006). The one most pertinent to this series and volume is 'a sudden or momentous change in a situation'. Recent years have seen an unprecedented explosion of interest in unfolded proteins in all of their various forms. Coupled with this increase in interest we have seen momentous changes in the way unfolded proteins are viewed. Two particular paradigms have come under close scrutiny: unfolded proteins are disordered random coils devoid of persistent structure, and protein function first requires protein structure. The first of these is currently a hotly debated subject. The second paradigm we can safely claim has been overturned. There is a second definition of revolution that is quite relevant to a significant portion of the work reviewed herein, in particular those chapters dealing with local and persistent structure in unfolded proteins. That definition is 'a turning or rotational motion about an axis' (The American Heritage Dictionary, 2006). About four decades ago, Charles Tanford (1968) demonstrated that highly denatured proteins possess hydrodynamic properties consistent with Paul Flory's random coil (Flory, 1969). Given that the Flory random coil definition included the stipulation that conformers making up the denatured state ensemble would differ in energy by just a few kT, there has been the assumption that denatured states must therefore be completely random in nature with no persistent structure or biases towards particular conformers. Notably however, Tanford did note the random coil-like hydrodynamic data he obtained did not necessarily rule out the presence of structure in denatured proteins (Tanford, 1968). Around the same time, Sam Krimm and M. Lois Tiffany noted that the CD spectra they obtained for proteins in the presence of high concentration of chemical denaturants had similarities to spectra obtained for homopolymers of proline, lysine, and glutamic acid in water (Tiffany and Krimm, 1968a, 1968b, 1973, 1974). Homopolymers of these residues were known to adopt the left-handed polyproline II conformation, leading Tiffany and Krimm to hypothesise that highly denatured proteins possess significant polyproline II helix content. Of these two views, that espousing the lack of structure in denatured proteins became more widely adopted and was, over time, adopted as a central paradigm in protein folding. As several of the chapters in this volume note, a Tiffany and Krimm-like view appears to be, to some extent, the more correct one. The level to which it is correct is still unknown, although it is clear that the polyproline II helical conformation is not the only, perhaps not even the most common, persistent conformation present in unfolded proteins. Thus we have come through a full circle or revolution. (from the preface)

Sheds new light on intrinsically disordered proteins and peptides, including their role in neurodegenerative diseases With the discovery of intrinsically disordered proteins and peptides (IDPs), researchers realized that proteins do not necessarily adopt a well defined secondary and tertiary structure in order to perform biological functions. In fact, IDPs play biologically relevant roles, acting as inhibitors, scavengers, and even facilitating DNA/RNA-protein interactions. Due to their propensity for self-aggregation and fibril formation, some IDPs are involved in neurodegenerative diseases such as Parkinson's and Alzheimer's. With contributions from leading researchers, this text reviews the most recent studies, encapsulating our understanding of IDPs. The authors explain how the growing body of IDP research is building our knowledge of the folding process, the binding of ligands to receptor molecules, and peptide self-aggregation. Readers will discover a variety of experimental, theoretical, and computational approaches used to better understand the properties and function of IDPs. Moreover, they'll discover the role of IDPs in human disease and as drug targets. Protein and Peptide Folding, Misfolding, and Non-Folding begins with an introduction that explains why research on IDPs has significantly expanded in the past few years. Next, the book is divided into three sections: Conformational Analysis of Unfolded States Disordered Peptides and Molecular Recognition Aggregation of Disordered Peptides Throughout the book, detailed figures help readers understand the structure, properties, and function of IDPs. References at the end of each chapter serve as a gateway to the growing body of literature in the field. With the publication of Protein and Peptide Folding, Misfolding, and Non-Folding, researchers now have a single place to discover IDPs, their diverse biological functions, and the many disciplines that have contributed to our evolving understanding of them.
