Available in PDF, EPUB and Kindle. Book excerpt: The RNA exosome is a multi-subunit protein complex involved in RNA maturation, surveillance, and turnover of cellular RNA. It is composed of a nine subunit core that contains an RNA binding central channel and associates with the additional subunit Rrp44. Rrp44 contains a 3' to 5' processive exoribonuclease activity and an endoribonuclease activity in its N-terminal PIN domain. The exosome is present in both the nucleus and cytoplasm. In the nucleus, the exosome associates with a second nuclease, Rrp6, which is a distributive 3' to 5' exoribonuclease. Although a wealth of studies have helped to characterize the exosome, it is still not entirely clear how the exosome core functions in concert with these two nucleases to degrade RNA. In this dissertation, I present structural and biochemical studies of both the Rrp44 and Rrp6 bound exosome. In particular, I have attempted to crystallize a sub-complex of Rrp44 bound to the exosome, and present data that suggest that structured RNA can access Rrp44 without being first channeled through the exosome. Despite this conclusion, the exosome core still appears to down-regulate both the exonuclease and endonuclease activities of Rrp44, possibly by causing the protein to assume a conformation that prohibits it from promiscuous RNA degradation. Work on the Rrp6 containing exosme was conducted in attempts of obtaining an EM reconstruction of this complex. Crystallization of an RNA and Rrp6 binding exosome associated iii protein, Rrp47, was also attempted alone and in complex with Rrp6. Overall, the results that I present here will help to further characterize the function of the exosome in RNA mediated degradation. iv.

Download or read book RNA Exosome written by Torben Heick Jensen and published by Springer Science & Business Media. This book was released on 2011-06-29 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diversity of RNAs inside living cells is amazing. We have known of the more “classic” RNA species: mRNA, tRNA, rRNA, snRNA and snoRNA for some time now, but in a steady stream new types of molecules are being described as it is becoming clear that most of the genomic information of cells ends up in RNA. To deal with the enormous load of resulting RNA processing and degradation reactions, cells need adequate and efficient molecular machines. The RNA exosome is arising as a major facilitator to this effect. Structural and functional data gathered over the last decade have illustrated the biochemical importance of this multimeric complex and its many co-factors, revealing its enormous regulatory power. By gathering some of the most prominent researchers in the exosome field, it is the aim of this volume to introduce this fascinating protein complex as well as to give a timely and rich account of its many functions. The exosome was discovered more than a decade ago by Phil Mitchell and David Tollervey by its ability to trim the 3’end of yeast, S. cerevisiae, 5. 8S rRNA. In a historic account they laid out the events surrounding this identification and the subsequent birth of the research field. In the chapter by Kurt Januszyk and Christopher Lima the structural organization of eukaryotic exosomes and their evolutionary counterparts in bacteria and archaea are discussed in large part through presentation of structures.

Download or read book RNA Structure and Function written by Jan Barciszewski and published by Springer Nature. This book was released on 2023-12-05 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the current status of our understanding of RNA, a key biological molecule. The various RNAs covered are messenger RNA, ribosomal RNA, transfer RNA, noncoding RNAs, modified nucleosides, and RNA enzymes. The different chapters detail methods to investigate RNA structure and function, the chemistry of modified RNAs, and the latest advances in our understanding of the vast array of biological processes in which RNA is involved. RNA, in one form or another, touches almost everything in a cell. RNA has both structural and catalytic properties. RNA fulfills a broad range of functions. These molecules are no longer seen as passive elements transferring the genetic information from DNA into proteins but regulate the activity of genes during development, cellular differentiation, and changing environments. RNAs are involved in various aspects of cell physiology and disease development. Discoveries of RNA with unexpected diverse functions in healthy and diseased cells, such as the role of RNA as both the source and countermeasure to cancer or severe viral infection, stimulate new trends, passion, and solutions for molecular medicine. In this book, fundamental questions about the biochemical and genetic importance of RNA, how mRNAs are generated and used to produce proteins, how noncoding and catalytic RNAs mediate key cellular processes, how to determine RNA structure and how to apply RNA in treatment of diseases. This book is an essential resource for researches in academia and industry contributing to the development of new RNA therapeutics. The book is geared toward scientists from the graduate level on up and particularly appeals to active investigators in RNA biology, molecular biology, and biochemistry.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the regulation of transcription and translation in Archaea and arising insights into the evolution of RNA processing pathways. From synthesis to degradation and the implications of gene expression, it presents the current state of knowledge on archaeal RNA biology in 13 chapters. Topics covered include the modification and maturation of RNAs, the function of small non-coding RNAs and the CRISPR-Cas defense system. While Archaea have long been considered exotic microbial extremophiles, they are now increasingly being recognized as important model microorganisms for the study of molecular mechanisms conserved across the three domains of life, and with regard to the relevance of similarities and differences to eukaryotes and bacteria. This unique book offers a valuable resource for all readers interested in the regulation of gene expression in Archaea and RNA metabolism in general.
Download or read book mRNA Processing and Metabolism written by Daniel R. Schoenberg and published by Humana. This book was released on 2004-02-05 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cells possess a wealth of posttranscriptional control mechanisms that impact on every conceivable aspect of the life of an mRNA. These processes are intimately intertwined in an almost baroque manner, where promoter context influences the recruitment of splicing factors, where the majority of pre-mRNAs undergo alternative splicing, and where proteins deposited during nuclear processing impact distal cytoplasmic processing, translation, and decay. If there is a unifying theme to mRNA Processing and Metabolism: Methods and Protocols, it is that mRNA processing and metabolism are integrated processes. Many of the techniques used to study mRNA have been described in a previous volume of this series (RNA–Protein Interaction Protocols, Susan Haynes, ed.) and specialized methods journals. In selecting topics for mRNA Processing and Metabolism: Methods and Protocols, I sought input on new and novel techniques and approaches that build on this foundation using technological advances in microscopy, whole genome sequencing, microarrays, mass spectrometry, fluorescent detection methodologies, and RNA interference. I have tried not to bias this book toward any single model organism, and approaches described in the various chapters use yeast, Drosophila, Xenopus, mice, plants, and cultured mammalian cells.

Download or read book The Biology of mRNA Structure and Function written by Marlene Oeffinger and published by Springer Nature. This book was released on 2019-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides an overview on the different aspects of gene regulation from an mRNA centric viewpoint, including how mRNA is assembled and self-assembles in a complex consisting of RNA and proteins, and how its ability to be translated at the right time and space depends on many processes acting on the mRNAs, leading to a properly folded complex. This book shows how new technologies have led to a better understanding of these processes and their connected diseases.The book is written for scientists in fundamental and applied biomedical research working on different aspects of gene regulation. It is also targeted to an audience that is not implicated in these fields directly, but wants to gain a better understanding of mRNA biology.
