Book Description
This book covers a topic that has been neglected for years and has returned to the spotlight only recently. Until the genetic role of DNA was firmly established, many researchers suspected that proteins, rather than nucleic acids, could be carriers of heritable information. However, these models were completely forgotten with the triumphal march of the double helix and the development of a central dogma postulating that information flow occurs strictly from DNA, through RNA, to protein, making it seemingly impossible for the proteins to possess a coding potential. Proteins were downgraded to the role of simple perpetuators and executors of DNA orders. Taken together, data included in this book prove beyond a reasonable doubt that proteins and multiprotein complexes are able to control heritable traits, and that, at least in some examples, this control occurs in a template-like fashion, so that new structures strictly reproduce patterns of pre-existing structures that were not specifically coded in DNA. Thus, protein-based inheritance has left the area of speculation and has emerged as a new topic amenable to high-quality experimental analysis.

The Three Functional States of Proteins
Author: Timir Tripathi
Publisher: Elsevier
ISBN: 0443218102
Category : Science
Languages : en
Pages : 1162
Book Description
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

The Epigenetics Revolution
Author: Nessa Carey
Publisher: Columbia University Press
ISBN: 0231530714
Category : Science
Languages : en
Pages : 353
Book Description
Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the twenty-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics. Nessa Carey, a leading epigenetics researcher, connects the field's arguments to such diverse phenomena as how ants and queen bees control their colonies; why tortoiseshell cats are always female; why some plants need cold weather before they can flower; and how our bodies age and develop disease. Reaching beyond biology, epigenetics now informs work on drug addiction, the long-term effects of famine, and the physical and psychological consequences of childhood trauma. Carey concludes with a discussion of the future directions for this research and its ability to improve human health and well-being.

Prions Prions Prions
Author: Stanley B. Prusiner
Publisher: Springer
ISBN: 9783540593430
Category : Medical
Languages : en
Pages : 163
Book Description
A series of remarkable discoveries in the past three decades have led to the molecular and genetic characterization of the transmissible pathogen causing scrapie in animals and a quartet of human illnesses: kuru, Jakob-Creutzfeld disease, Gerstmann-Sträussler-Scheinker disease, and fatal familial insomnia. To distinguish this pathogen from viruses and viroids, the term "prion" was introduced to emphasize its proteinaceous and infectious nature. Stanley B. Prusiner, editor of this volume, was awarded the 1997 Nobel Prize in Physiology and Medicine for his pioneering discovery of prions. The book reviews advances in studies of prions, which - as considereable evidence indicates - are novel pathogens composed only of protein.

Epigenetic Mechanisms of Gene Regulation
Author: Vincenzo E. A. Russo
Publisher:
ISBN:
Category : Medical
Languages : en
Pages : 716
Book Description
Many inheritable changes in gene function are not explained by changes in the DNA sequence. Such epigenetic mechanisms are known to influence gene function in most complex organisms and include effects such as transposon function, chromosome imprinting, yeast mating type switching and telomeric silencing. In recent years, epigenetic effects have become a major focus of research activity. This monograph, edited by three well-known biologists from different specialties, is the first to review and synthesize what is known about these effects across all species, particularly from a molecular perspective, and will be of interest to everyone in the fields of molecular biology and genetics.

Protein Misfolding and Disease
Author: Peter Bross
Publisher: Springer Science & Business Media
ISBN: 1592593941
Category : Science
Languages : en
Pages : 317
Book Description
For decades it has been known that structured conformations are important for the proper functioning of most cellular proteins. However, appreciation that protein folding to the functional conformations as well as the structural maintenance of protein molecules are very complex processes has only emerged during the last ten years. The intimate interplay uncovered by this scientific development led us to realize that perturbations of the protein folding process and disturbances of conformational maintenance are major disease mechanisms. This development has given rise to the concept of conformational diseases and the broader signature of protein folding diseases, comprising diseases in which mutations or environmental stresses may result in a partial misfolding that leads then to alternative conformations capable of disturbing cellular processes. This may happen by self-association (aggregation), as in prion and Alzheimer’s diseases, or by incorporation of alternatively folded subunits into structural entities, as in collagen diseases. Another possibility is that folding to the native structure is impaired or abolished, resulting in decreased stea- state levels of the correctly folded protein, as is observed in cystic fibrosis and 1-antitrypsin deficiency, as well as in many enzyme deficiencies. In addition, deficiencies of proteins that are engaged in assisting and supervising protein folding (protein quality control) may impair the folding of many other proteins, resulting in pathological phenotypes. Examples of this are the spastic paraplegia attributable to mutations in mitochondrial protease/chaperone complexes.
