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.

Published in 2014, Protein Deimination in Human Health and Disease was the first book on this novel post-translational modification, in which selected positively-charged arginine amino acids are converted to neutral citrulline amino acids by the peptidyl-arginine deiminase (PAD) family of enzymes. This area of research continues to expand rapidly, necessitating the need for this second edition. Chronicling the latest inflammatory, epigenetic, neurodegenerative, and carcinogenic processes, Protein Deimination in Human Health and Disease, Second Edition, updates the latest advances in deimination research, including new information on PAD enzyme structure and activity, and how PAD knock-out animals are being used to study known and newly-discovered links to various human diseases. The first edition outlined what was known about citrullinated proteins in normal tissues such as skin and hair, as well as in maladies such as rheumatoid arthritis (RA), multiple sclerosis (MS), Alzheimer's disease (AD), glaucoma, peripheral nerve injury, neonatal hypoxic brain damage, and breast cancer. This second edition addresses numerous additional disorders such as diabetes, asthma, traumatic brain injury, inflammatory bowel disease, lupus, bone disease, heart failure, fronto-temporal dementia, and prostate and colon cancer. It also provides updates on the deimination research covering the three seminal diseases first linked to this process (RA, MS and AD), and details how auto-antibodies against citrullinated proteins contribute to disease. In addition, new hypotheses on the possible pathologic mechanisms of citrullinated myelin basic protein and glial fibrillary acidic protein are also proposed. This second edition also outlines the latest developments in therapeutic strategies, including the use of new PAD antagonists and innovative techniques such as micro-vescicles and stem cells as possible mechanisms to treat these conditions.

Metal toxicity and deficiency are both common abiotic problems faced by plants. While metal contamination around the world is a critical issue, the bioavailability of some essential metals like zinc (Zn) and selenium (Se) can be seriously low in other locations. The list of metals spread in high concentrations in soil, water and air includes several toxic as well as essential elements, such as arsenic (As), cadmium (Cd), chromium (Cr), aluminum (Al), and selenium (Se). The problems for some metals are geographically confined, while for others, they are widespread. For instance, arsenic is an important toxic metalloid whose contamination in Southeast Asia and other parts of world is well documented. Its threats to human health via food consumption have generated immense interest in understanding plants' responses to arsenic stress. Metals constitute crucial components of key enzymes and proteins in plants. They are important for the proper growth and development of plants. In turn, plants serve as sources of essential elements for humans and animals. Studies of their physiological effects on plants metabolism have led to the identification of crucial genes and proteins controlling metal uptake and transport, as well as the sensing and signaling of metal stresses. Plant-Metal Interactions sheds light on the latest development and research in analytical biology with respect to plant physiology. More importantly, it showcases the positive and negative impacts of metals on crop plants growth and productivity.

This book reflects more than three decades of research on Cellular Automata (CA), and nearly a decade of work on the application of CA to model biological strings, which forms the foundation of 'A New Kind of Computational Biology' pioneered by the start-up, CARLBio. After a brief introduction on Cellular Automata (CA) theory and functional biology, it reports on the modeling of basic biological strings with CA, starting with the basic nucleotides leading to codon and anti-codon CA models. It derives a more involved CA model of DNA, RNA, the entire translation process for amino acid formation and the evolution of protein to its unique structure and function. In subsequent chapters the interaction of Proteins with other bio-molecules is also modeled. The only prior knowledge assumed necessary is an undergraduate knowledge of computer programming and biology. The book adopts a hands-on, "do-it-yourself" approach to enable readers to apply the method provided to derive the CA rules and comprehend how these are related to the physical 'rules' observed in biology. In a single framework, the authors have presented two branches of science - Computation and Biology. Instead of rigorous molecular dynamics modeling, which the authors describe as a Bottoms-Up model, or relying on the Top-Down new age Artificial Intelligence (AI) and Machine Language (ML) that depends on extensive availability of quality data, this book takes the best from both the Top-Down and Bottoms-up approaches and establishes how the behavior of complex molecules is represented in CA. The CA rules are derived from the basic knowledge of molecular interaction and construction observed in biological world but mapped to a few subset of known results to derive and predict results. This book is useful for students, researchers and industry practitioners who want to explore modeling and simulation of the physical world complex systems from a different perspective. It raises the inevitable the question - 'Are life and the universe nothing but a collection of continuous systems processing information'.

Experts from around the world review the current field of the immunobiology of heat shock proteins, and provide a comprehensive account of how these molecules are spearheading efforts in the understanding of various pathways of the immune system. This one-stop resource contains numerous images to both help illustrate the research on heat shock proteins, and better clarify the field for the non-expert. Heat shock proteins (HSPs) were discovered in 1962 and were quickly recognized for their role in protecting cells from stress. Twenty years later, the immunogenicity of a select few HSPs was described, and for the past 30 years, these findings have been applied to numerous branches of immunology, including tumor immunology and immunosurveillance, immunotherapy, etiology of autoimmunity, immunotherapy of infectious diseases, and expression of innate receptors. While HSPs can be used to manipulate immune responses by exogenous administration, they appear to be involved in initiation of de novo immune responses to cancer and likely in the maintenance of immune homeostasis.

Poly (ADP-ribose) Polymerases (PARPs) are abundant and ubiquitous proteins that regulate crucial processes of the cell cycle, DNA repair, genomic stability, and transcriptional regulation. Being involved in basic cell functions, PARPs mediate rapid responses to such environmental factors as stress, infection, nutrition and hormonal signals. Whereas PARP inhibitors can suppress tumor growth and proliferation in certain breast, ovarian, and prostate cancers, understanding how PARP controls cellular functions is essential for the development of novel cancer treatments strategies. Divided into three convenient sections, Poly(ADP-Ribose) Polymerase: Methods and Protocols aims to explain how PARP proteins act within the normal development of an organism as well as in pathogenic conditions, seeks to advance the knowledge of developmental pathways regulation, and endeavors to facilitate the development of new therapeutic drugs and methods to target PARP-dependent processes. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Poly(ADP-Ribose) Polymerase: Methods and Protocols serves as an ideal guide to scientists who wish to continue exploring this exciting and progressive research field.

Receptor Tyrosine Kinase: Structure, Functions and Role in Human Disease, for the first time, systematically covers the shared structural and functional features of the RTK family. Receptor Tyrosine Kinases (RTKs) play critical roles in embryogenesis, normal physiology and several diseases. And over the last decade they have become the Number 1 targets of cancer drugs. To be able to conduct fundamental research or to attempt to develop pharmacological agents able to enhance or intercept them, it is essential first to understand the evolutionary origin of the 58 RTKs and their roles in invertebrates and in humans, as well as downstream signaling pathways. The assembly of chapters is written by experts and underscores commonalities between and among the RTKs. It is an ideal companion volume to The Receptor Tyrosine Kinase: Families and Subfamilies, which proceeds, family by family through all of the specific subfamilies of RTKs, along with their unique landmarks.

This book presents modern and classic analytical approaches that are crucial for the biochemical and functional characterization of the archetypal protein, glyceraldehyde-3-phosphate dehydrogenase (GAPDH). The distinguishing feature of the book is that it covers, in addition to other methods, some of the uncommon but valuable techniques as well. For example, in-gel visualization of enzyme activity, immunoblotting protocols for native (non-denatured) proteins, and proteins resolved by pH-gradient [IEF-isoelectrofocusing], etc. These expedient methods are relevant and vital for the verification of biochemical properties of GAPDH, or similar protein of interest. This work outlines detailed protocols that are essential to investigate classical (cellular) and recently reported extracellular (secretory) isoforms of GAPDH. Precisely, the book covers techniques pertinent to enzymatic and non-enzymatic analysis of GAPDH that include, but not limited to, electrophoretic mobility shift assay (EMSA), two-dimensional (2D)-immunoblotting, immunofluorescence/confocal microscopy, mass spectrometry, ion-exchange and affinity chromatography. Readers will discover the importance of the experimental methods described in the book as they relate to the evaluation of the role and significance of GAPDH. Furthermore, majority of the methods described in the book have also been validated in the author's laboratory, besides other research groups worldwide, underlining the repeatability and reproducibility of the protocols. Each method begins with an abstract and a brief background emphasizing its application and relevance. This will enable the readers to determine the choice of experimental design according to their research objectives. The book explains the methods systematically with ample illustrations to facilitate quick and easy comprehension of the practical knowledge. Although the book is focused on GAPDH, many of the protocols may be adopted to other proteins or enzymes with minimal modifications. Noteworthy, it is unequivocally established that GAPDH is a multifunctional protein involved in several cellular processes of health & disease conditions. Hence, this book will be a valuable practical guide for young researchers, scientists and clinician-scientists.

This work establishes linear-scaling density-functional theory (DFT) as a powerful tool for understanding enzyme catalysis, one that can complement quantum mechanics/molecular mechanics (QM/MM) and molecular dynamics simulations. The thesis reviews benchmark studies demonstrating techniques capable of simulating entire enzymes at the ab initio quantum-mechanical level of accuracy. DFT has transformed the physical sciences by allowing researchers to perform parameter-free quantum-mechanical calculations to predict a broad range of physical and chemical properties of materials. In principle, similar methods could be applied to biological problems. However, even the simplest biological systems contain many thousands of atoms and are characterized by extremely complex configuration spaces associated with a vast number of degrees of freedom. The development of linear-scaling density-functional codes makes biological molecules accessible to quantum-mechanical calculation, but has yet to resolve the complexity of the phase space. Furthermore, these calculations on systems containing up to 2,000 atoms can capture contributions to the energy that are not accounted for in QM/MM methods (for which the Nobel prize in Chemistry was awarded in 2013) and the results presented here reveal profound shortcomings in said methods.
