This book was released on 2021-09-25 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ribosome biogenesis is the process of making ribosomes which are responsible for mRNA translation into proteins. It is a tightly regulated process closely linked to nearly all biochemical and cellular processes, including cell division, growth, and development. Emerging Concepts in Ribosome Structure, Biogenesis, and Function provides a synthesized overview of all the parts engaged in this process. The book begins by providing an introduction to the ribosome factory, its origin, and its evolution of translation. It then goes on to describe ribosome structure including subunits, RNA, and protein components. Ribosome biogenesis and its emergence as a frontier research area for translational potential in cancer and other diseases are also discussed. In addition, the book explores current developments in ribosome research like the emergence of ribosomopathies, how deregulation of ribosome biogenesis can impact disease mechanisms and aging, and the discovery of specialized ribosomes that have specific functions that may translate differentially with consequences on normal and pathological processes. Emerging Concepts in Ribosome Structure, Biogenesis, and Function provides fundamental coverage and emerging research on ribosomes, biogenesis, and their structure and function and is a resourceful introduction for new researchers and those engaged in interdisciplinary ribosomal research. - Provides an overview of ribosome biogenesis and examines its involvement in cell transformation and cancerous growth - Covers disorders related to the ribosome (ribosomopathies) and explains the significance of ribosome dysfunction in human diseases - Includes commonly used methods to study ribosomes, such as polysome preparation, RNA profiling and proteomics, CryoEM, and Cell-free assays along with proper illustrations

This book was released on 2011-12-10 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ribosome is a macromolecular machine that synthesizes proteins with a high degree of speed and accuracy. Our present understanding of its structure, function and dynamics is the result of six decades of research. This book collects over 40 articles based on the talks presented at the 2010 Ribosome Meeting, held in Orvieto, Italy, covering all facets of the structure and function of the ribosome. New high-resolution crystal structures of functional ribosome complexes and cryo-EM structures of translating ribosomes are presented, while partial reactions of translation are examined in structural and mechanistic detail, featuring translocation as a most dynamic process. Mechanisms of initiation, both in bacterial and eukaryotic systems, translation termination, and novel details of the functions of the respective factors are described. Structure and interactions of the nascent peptide within, and emerging from, the ribosomal peptide exit tunnel are addressed in several articles. Structural and single-molecule studies reveal a picture of the ribosome exhibiting the energy landscape of a processive Brownian machine. The collection provides up-to-date reviews which will serve as a source of essential information for years to come.

Available in PDF, EPUB and Kindle. Book excerpt: This Open Access volume provides comprehensive reviews and describes the latest techniques to study eukaryotic ribosome biogenesis. For more than 50 years ribosomes are a major research topic. Our knowledge about ribosome biogenesis and function such as transcription, mRNA modification, and translation was the sine qua non for developing the powerful RNA-based vaccines against RNA-viruses causing the world-threatening Covid-19 pandemia. The chapters in this book are organized into six parts. Part One discusses a comparative survey about the unity and diversity of ribosome biogenesis in pro- and eukaryotic cells. Part Two deals with the genomic organization of eukaryotic rDNA and the role of RNA polymerase I in ribosomal RNA transcription. Part Three explores in vitro methods to study RNA polymerase I structure and its function, and Part Four analyzes the nucleo-cytoplasmic transport of assembled ribosomes and RNP complexes. Part Five covers modifications that increase the complexity of rRNAs, and Part Six provides readers with a review of eukaryotic translation and - for the first time - describes a new method to analyze translation in vitro. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and comprehensive, Ribosome Biogenesis: Methods and Protocols is a valuable resource for scientists and researchers interested in learning more about the increasing importance of in vitro RNA-technologies.

Available in PDF, EPUB and Kindle. Book excerpt: Dysfunction of nuclear-cytoplasmic transport systems has been associated with many human diseases. Thus, understanding of how functional this transport system maintains, or through dysfunction fails to maintain remains the core question in cell biology. In eukaryotic cells, the nuclear envelope (NE) separates the genetic transcription in the nucleus from the translational machinery in the cytoplasm. Thousands of nuclear pore complexes (NPCs) embedded on the NE selectively mediate the bidirectional trafficking of macromolecules such as RNAs and proteins between these two cellular compartments. In this book, the authors integrate recent progress on the structure of NPC and the mechanism of nuclear-cytoplasmic transport system in vitro and in vivo.

This book was released on 2012-12-06 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nucleolus had consistently attracted the attention of investigators in the fields of cell biology and pathology. Because of its ubiquitous presence in the nucleus of eukaryotic cells, its rapid changes during their life cycle, and its rapid response to noxious agents, this organelle has been the subject of a large number of studies. Yet, the exact function and the very reason for the existence of the nucleolus (the only large cellular structure not delimited by a membrane) remain largely unknown. The ribosomes were discovered relatively late in the study of cells, but due to their crucial involvement in the protein synthesis machinery of all living organisms, the elucidation of their structure and function quickly became one of the major goals of molecular biology. The relatively simple structure of the ribosome strengthens the hope that a full understanding of the structure and function of this organelle in molecular terms is within the reach of contemporary research~ Since each of the rRNA and protein molecules embodied in the ribosome is the product of a distinct gene, studies on the biogenesis of ribosomes expanded rapidly to become a core topic in molecular genetics.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Ribosomes are intricate molecular machines ensuring proper protein synthesis in every cell. Ribosome biogenesis is a complex process which has been intensively analyzed in bacteria and eukaryotes. In contrast, our understanding of the in vivo archaeal ribosome biogenesis pathway remains less characterized. Here, we have analyzed the in vivo role of the almost universally conserved ribosomal RNA dimethyltransferase KsgA/Dim1 homolog in archaea. Our study reveals that KsgA/Dim1-dependent 16S rRNA dimethylation is dispensable for the cellular growth of phylogenetically distant archaea. However, proteomics and functional analyses suggest that archaeal KsgA/Dim1 and its rRNA modification activity (i) influence the expression of a subset of proteins and (ii) contribute to archaeal cellular fitness and adaptation. In addition, our study reveals an unexpected KsgA/Dim1-dependent variability of rRNA modifications within the archaeal phylum. Combining structure-based functional studies across evolutionary divergent organisms, we provide evidence on how rRNA structure sequence variability (re-)shapes the KsgA/Dim1-dependent rRNA modification status. Finally, our results suggest an uncoupling between the KsgA/Dim1-dependent rRNA modification completion and its release from the nascent small ribosomal subunit. Collectively, our study provides additional understandings into principles of molecular functional adaptation, and further evolutionary and mechanistic insights into an almost universally conserved step of ribosome synthesis

Download or read book Structure and Function of the Archaeal Box C/D Ribonucleoprotein Complex written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Box C/D ribonucleoprotein complexes (RNPs) are evolutionarily ancient nucleotide modification machines found in both Eukarya and Archaea. The box C/D RNAs are essential for ribosome biogenesis and primarily function by guiding 2'-O-methylation of ribosomal RNA (rRNA). The site of modification is determined by base-pairing between the target RNA and the box C/D RNA through a region of complementarity. The box C/D RNAs possess terminal box C/D and internal C'/D' motifs that fold to form K-turn RNA elements. In eukaryotes, the box C/D RNAs associate with a common set of four core proteins to form an RNP. The core proteins, 15.5kD, Nop56p, Nop58p and Fibrillarin, are differentially distributed on eukaryotic box C/D RNAs to form an asymmetric RNPs. We have characterized the structure and function of the archaeal box C/D RNP using Methanocaldococcus jannaschii sR8 RNP as a model box C/D complex. Archaeal genomes contain genes for a Fibrillarin homolog and a single homolog for both Nop56p and Nop58p termed Nop56/58p. Our initial investigations identified ribosomal protein L7 as the archaeal homolog of the eukaryotic 15.5kD protein. Strikingly, L7 has a dual role as a component of both the ribosome and the box C/D RNP. A methylation-competent sR8 RNP was assembled in vitro using the three recombinant M. jannaschii box C/D RNA core proteins. This reconstituted complex is symmetric with respect to core protein binding and guides nucleotide modification from both the box C/D and C'/D' RNPs. Additionally, efficient RNA 2'-O-methylation requires juxtaposed box C/D and C'/D' motifs on the same box C/D RNP complex. Finally, the identification of box C/D RNPs in both Archaea and Eukarya led us to question the evolutionary origins of these ancient modification complexes. Based on the demonstration of a common RNP element (L7: K-turn motif) in both the archaeal large ribosomal subunit and the box C/D RNP complex, we propose that the trans-acting nucleotide modification machines evolv.

Available in PDF, EPUB and Kindle. Book excerpt: During the past few decades we have witnessed an era of remarkable growth in the field of molecular biology. In 1950 very little was known of the chemical constitution of biological systems, the manner in which information was transmitted from one organism to another, or the extent to which the chemical basis of life is unified. The picture today is dramati cally different. We have an almost bewildering variety of information de tailing many different aspects of life at the molecular level. These great advances have brought with them some breath-taking insights into the molecular mechanisms used by nature for replicating, distributing, and modifying biological information. We have learned a great deal about the chemical and physical nature of the macromolecular nucleic acids and proteins, and the manner in which carbohydrates, lipids, and smaller mole cules work together to provide the molecular setting of living systems. It might be said that these few decades have replaced a near vacuum of information with a very large surplus. It is in the context of this flood of information that this series of mono graphs on molecular biology has been organized. The idea is to bring together in one place, between the covers of one book, a concise assessment of the state of the subject in a well-defined field.
