Available in PDF, EPUB and Kindle. Book excerpt: Pumilio/feminization of XX and XO animals (fem)-3 mRNA-binding factor (PUF) proteins bind sequence specifically to mRNA targets using a single-stranded RNA-binding domain comprising eight Pumilio (PUM) repeats. PUM repeats have now been identified in proteins that function in pre-rRNA processing, including human Puf-A and yeast Puf6. This is a role not previously ascribed to PUF proteins. In this paper we present crystal structures of human Puf-A that reveal a class of nucleic acid-binding proteins with 11 PUM repeats arranged in an "L"--Like shape. In contrast to classical PUF proteins, Puf-A forms sequence-independent interactions with DNA or RNA, mediated by conserved basic residues. We demonstrate that equivalent basic residues in yeast Puf6 are important for RNA binding, pre-rRNA processing, and mRNA localization. Finally, PUM repeats can be assembled into alternative folds that bind to structured nucleic acids in addition to forming canonical eight-repeat crescent-shaped RNA-binding domains found in classical PUF proteins.

Book Synopsis RNA Metabolism in Neurodegenerative Diseases by : Rita Sattler
Download or read book RNA Metabolism in Neurodegenerative Diseases written by Rita Sattler and published by Springer. This book was released on 2018-06-18 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has become evident over the last years that abnormalities in RNA processing play a fundamental part in the pathogenesis of neurodegenerative diseases. Cellular viability depends on proper regulation of RNA metabolism and subsequent protein synthesis, which requires the interplay of many processes including transcription, pre--‐mRNA splicing, mRNA editing as well as mRNA stability, transport and translation. Dysfunction in any of these processes, often caused by mutations in the coding and non--‐ coding RNAs, can be very destructive to the cellular environment and consequently impair neural viability. The result of this RNA toxicity can lead to a toxic gain of function or a loss of function, depending on the nature of the mutation. For example, in repeat expansion disorders, such as the newly discovered hexanucleotide repeat expansion in theC9orf72 gene found in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), a toxic gain of function leads to the formation of RNA foci and the sequestration of RNA binding proteins (RBPs). This in return leads to a loss of function of those RBPs, which is hypothesized to play a significant part in the disease progression of ALS and FTD. Other toxicities arising from repeat expansions are the formation of RNA foci, bi--‐directional transcription and production of repeat associated non--‐ATG (RAN) translation products. This book will touch upon most of these disease mechanisms triggered by aberrant RNA metabolism and will therefore provide a broad perspective of the role of RNA processing and its dysfunction in a variety of neurodegenerative disorders, including ALS, FTD, Alzheimer’s disease, Huntington’s disease, spinal muscular atrophy, myotonic dystrophy and ataxias. The proposed authors are leading scientists in the field and are expected to not only discuss their own work, but to be inclusive of historic as well as late breaking discoveries. The compiled chapters will therefore provide a unique collection of novel studies and hypotheses aimed to describe the consequences of altered RNA processing events and its newest molecular players and pathways.

Book Synopsis Systems Biology of RNA Binding Proteins by : Gene W. Yeo
Download or read book Systems Biology of RNA Binding Proteins written by Gene W. Yeo and published by Springer. This book was released on 2014-09-08 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: After transcription in the nucleus, RNA binding proteins (RBPs) recognize cis-regulatory RNA elements within pre-mRNA sequence to form mRNA-protein (mRNP) complexes. Similarly to DNA binding proteins such as transcription factors that regulate gene expression by binding to DNA elements in the promoters of genes, RBPs regulate the fate of target RNAs by interacting with specific sequences or RNA secondary structural features within the transcribed RNA molecule. The set of functional RNA elements recognized by RBPs within target RNAs and which control the temporal, functional and spatial dynamics of the target RNA define a putative “mRNP code”. These cis-regulatory RNA elements can be found in the 5’ and 3’ untranslated regions (UTRs), introns, and exons of all protein-coding genes. RNA elements in 5’ and 3’ UTRs are frequently involved in targeting RNA to specific cellular compartments, affecting 3’ end formation, controlling RNA stability and regulating mRNA translation. RNA elements in introns and exons are known to function as splicing enhancers or silencers during the splicing process from pre-mRNA to mature mRNA. This book provides case studies of RNA binding proteins that regulate aspects of RNA processing that are important for fundamental understanding of diseases and development. Chapters include systems-level perspectives, mechanistic insights into RNA processing and RNA Binding proteins in genetic variation, development and disease. The content focuses on systems biology and genomics of RNA Binding proteins and their relation to human diseases.
Book Synopsis Human Intestinal Flukes by : Jong-Yil Chai
Download or read book Human Intestinal Flukes written by Jong-Yil Chai and published by Springer Nature. This book was released on 2019-08-22 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides up-to-date information on the characteristics of each species of intestinal fluke found in humans and on the management of infections caused by these trematodes. Biology, epidemiology, host-parasite relationships, pathogenicity, clinical aspects, diagnosis, and treatment are all reviewed in detail. The zoonotic intestinal flukes comprise 38 genera belonging to 16 families. They are morphologically diverse and each species has a characteristic life cycle and geographical distribution. Intestinal fluke infections are commonly considered as tropical endemic diseases in Asian countries, where 6 million people are infected, but the geographical limits and populations at risk are expanding and changing owing to a range of factors, including growing international markets, improved transportation systems, changes in eating habits, demographic trends, and climate change. While the pathogenicity of intestinal flukes is generally mild, the impact in immunocompromised individuals requires clarification and some diagnostic problems remain to be solved. In exploring all aspects of human intestinal fluke infections, this book will be invaluable for clinicians and researchers alike.

Book excerpt: This book provides a comprehensive overview of topics describing the earliest steps of fertilization, from egg activation and fertilization to the activation of the zygotic genome, in various studied vertebrate model systems. The contribution of maternal and paternal factors and their role in the early embryo as parental DNA becomes modified and embryonic genes become activated is fundamental to the initiation of embryogenesis in all animal systems. It can be argued that this is a unique developmental period, when information from the parents is compressed to direct the development of the body plan of the entire organism, a process of astounding simplicity, elegance and beauty. In addition to their fundamental scientific interest, many frontiers of biomedicine, such as reproductive biology, stem cells and reprogramming, and the understanding of intergenerational diseases, depend on advances in our knowledge of these early processes. Vertebrate Development: Maternal to Zygotic Control brings together chapters from experts in various disciplines describing the latest advances related to this important developmental transition. Each chapter is a synthesis of knowledge relevant to all vertebrates, with details on specific systems as well as comparisons between the various studied vertebrate models. The editorial expertise encompasses the fields of major vertebrate model systems (mammalian, amphibian and teleost) ensuring a balanced approach to various topics. This unique book—with its combination of in-depth and up-to-date basic research, inter-species comprehensiveness and emphasis on the very early stages of animal development—is essential for research scientists studying vertebrate development, as well as being a valuable resource for college educators teaching advanced courses in developmental biology.

Book Synopsis The Oxford Handbook of Neuronal Protein Synthesis by : Wayne S. Sossin
Download or read book The Oxford Handbook of Neuronal Protein Synthesis written by Wayne S. Sossin and published by Oxford University Press. This book was released on 2021-04-15 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Translational control in the nervous system is important. Many physiological processes in the nervous system depend on accurate control of the proteome that is mediated through protein synthetic mechanisms and thus, the nervous system is very sensitive to dysregulation of translational control. The Oxford Handbook of Neuronal Protein Synthesis reviews the mechanisms of translational control used by the nervous system, as well as how important nervous system functions, such as plasticity and homeostasis, depend on accurate translational control. The handbook extensively covers how dysregulation of protein synthesis can manifest itself in many distinct pathological processes including neurodevelopmental, neuropsychiatric, and neurodegenerative diseases. The handbook is comprehensive in its coverage of translational control mechanisms with particular focus on how these general control mechanisms are specifically utilized in the context of the cell biological constraints of the nervous system from both a mechanistic and systems perspective.
