Book Description
The cellular prion protein PrPC is a ubiquitous GPI-anchored protein. While PrPC has been the focus of intense research for its involvement in a group of neurodegenerative disorders known as transmissible spongiform encephalopathies (TSE), much less attention has been devoted to its physiological function. This notably relates to the lack of obvious abnormalities of mice, goat or cattle lacking PrPC. This apparently normal phenotype in these PrPC-deficient animals however contrasts with the very high degree of conservation of the prion protein gene (Prnp) in mammalian species (over 80%), and the presence of genes with similarities to Prnp in birds, reptiles, amphibians and fish. This high conservation together with its ubiquitous expression, - albeit at highest levels in the brain-, suggest that PrPC has major physiological functions. Dissecting PrPC function is further complicated by the occurrence, in mammals, of two potentially partially redundant homologues, Doppel, and Shadoo. The biological overlaps between members of the prion protein family are still under investigation and much debated. Similarly, although in vitro analyses have suggested various functions for PrPC, notably in cell death and survival processes, some have yielded conflicting results and/or discrepancies with in vivo studies. This Research Topic brings together the accumulated knowledge regarding the biological roles of the prion protein family, from the animal to the molecular scale.

Book Description
Gene duplication has long been believed to have played a major role in the rise of biological novelty through evolution of new function and gene expression patterns. The first book to examine gene duplication across all levels of biological organization, Evolution after Gene Duplication presents a comprehensive picture of the mechanistic process by which gene duplication may have played a role in generating biodiversity. Key Features: Explores comparative genomics, genome evolution studies and analysis of multi-gene families such as Hox, globins, olfactory receptors and MHC (immune system) A complete post-genome treatment of the topic originally covered by Ohno's 1970 classic, this volume extends coverage to include the fate of associated regulatory pathways Taps the significant increase in multi-gene family data that has resulted from comparative genomics Comprehensive coverage that includes opposing theoretical viewpoints, comparative genomics data, theoretical and empirical evidence and the role of bioinformatics in the study of gene duplication This up-to-date overview of theory and mathematical models along with practical examples is suitable for scientists across various levels of biology as well as instructors and graduate students.

Book Description
This two-volume encyclopedia examines the history, characteristics, causes, and treatment of genetic disease, as well as the science of genetics itself. Modern science has unlocked many of the mysteries of genetics, providing a blueprint for understanding the origins behind previously mysterious ailments and conditions, both common and uncommon. A complete understanding remains elusive, however: geneticists are still refining theories about what causes chromosomes to mutate, and genetic diseases remain difficult to diagnose and challenging to treat. This fascinating reference explores the scientific and human aspects of this complex field of science. Encyclopedia of Human Genetics and Disease features nearly 400 entries, including well-known genetic diseases, rare and lesser-known genetic diseases, and the genetic factors that may contribute to common diseases and health conditions, such as breast cancer and obesity. The author presents in-depth discussions of concepts essential to understanding genetic disease in 18 entries that provide background on key topics, such as "Genetics 101," the genome and the foundations of genetics, genetic counseling, and newborn screening. Each of the 355 disorders profiled provides the history of the condition, its prevalence, causes, treatment (if any), and further reading. Interesting sidebars and compelling photos that help inform content accompany many entries.

Book Description
This book covers important topics such as the dynamic structure and function of the 26S proteasome, the DNA replication machine: structure and dynamic function and the structural organization and protein–protein interactions in the human adenovirus capsid, to mention but a few. The 18 chapters included here, written by experts in their specific field, are at the forefront of scientific knowledge. The impressive integration of structural data from X-ray crystallography with that from cryo-electron microscopy is apparent throughout the book. In addition, functional aspects are also given a high priority. Chapter 1 is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

Book Description
Human Prion Diseases, Volume 153 is designed to update the reader on the latest advances and clinical aspects of prion diseases. The book is organized into five sections, including the pathophysiology of prions and a description of animal and human diseases. This is followed by detailed reports on recent advances in diagnosis strategies for the development of novel anti-prion molecules and possible designs of clinical trials in such a rare disease. An introductory chapter gives an extensive historical background of prion research, with a final chapter highlighting recent progress, and more importantly, unsolved problems. - Offers an authoritative overview of prion diseases in humans, detailing the pathogenesis of the disease, clinical investigations, and the diagnosis of both the genetic and acquired forms - Provides clarity and context by presenting prion diseases in relation to other neurodegenerative diseases in humans - Emphasizes the unique properties of prion diseases and consequent problems they can cause, both clinically and in public health terms
