Download or read book Pre mRNA Processing written by Angus I. Lamond and published by Springer. This book was released on 2014-08-23 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: he past fifteen years have seen tremendous growth in our understanding of T the many post-transcriptional processing steps involved in producing func tional eukaryotic mRNA from primary gene transcripts (pre-mRNA). New processing reactions, such as splicing and RNA editing, have been discovered and detailed biochemical and genetic studies continue to yield important new insights into the reaction mechanisms and molecular interactions involved. It is now apparent that regulation of RNA processing plays a significant role in the control of gene expression and development. An increased understanding of RNA processing mechanisms has also proved to be of considerable clinical importance in the pathology of inherited disease and viral infection. This volume seeks to review the rapid progress being made in the study of how mRNA precursors are processed into mRNA and to convey the broad scope of the RNA field and its relevance to other areas of cell biology and medicine. Since one of the major themes of RNA processing is the recognition of specific RNA sequences and structures by protein factors, we begin with reviews of RNA-protein interactions. In chapter 1 David Lilley presents an overview of RNA structure and illustrates how the structural features of RNA molecules are exploited for specific recognition by protein, while in chapter 2 Maurice Swanson discusses the structure and function of the large family of hnRNP proteins that bind to pre-mRNA. The next four chapters focus on pre-mRNA splicing.

Download or read book Eukaryotic MRNA Processing written by Adrian Krainer and published by IRL Press. This book was released on 1997 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the major aspects of post-transcriptional mRNA processing in the nucleus of eukaryotic cells. Each of the described mRNA reactions is required for proper gene expression and can also serve as a control point for regulating the expression of many genes, for example duringembryonic development or in different cell types. The different chapters review the assembly of newly synthesized nuclear mRNA transcripts into hnRNP particles and catalytically active spliceosomes; the structure and mechanism of action of small nuclear ribonucleoprotein particles and proteinfactors that catalyse pre-mRNA splicing in mammalian cells and in yeast; the regulation of gene expression and generation of protein isoform diversity by alternative splicing; the mechanisms of 3' end cleavage and polyadenylation; the architecture of the cell nucleus in relation to these processesand to the localization of the relevant substrates and factors; the diverse mechanisms of RNA processing by ribozymes and their potential relevance for nuclear mRNA processing; the mechanism of spliced-leader addition by trans-splicing in nematodes and trypanosomes; and the process ofinsertion/deletion mRNA editing in kinetoplasmid protozoa. In each chapter, leading researchers have provided detailed, critical reviews of the history, experimental approaches, major advances, current ideas and models, as well as future directions, for each of these active areas of research.

Download or read book Regulation of Alternative Splicing written by Philippe Jeanteur and published by Springer Science & Business Media. This book was released on 2002-10-21 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery in 1977 that genes are split into exons and introns has done away with the one gene - one protein dogma. Indeed, the removal of introns from the primary RNA transcript is not necessarily straightforward since there may be optional pathways leading to different messenger RNAs and consequently to different proteins. Examples of such an alternative splicing mechanism cover all fields of biology. Moreover, there are plenty of occurrences where deviant splicing can have pathological effects. Despite the high number of specific cases of alternative splicing, it was not until recently that the generality and extent of this phenomenon was fully appreciated. A superficial reading of the preliminary sequence of the human genome published in 2001 led to the surprising, and even deceiving to many scientists, low number of genes (around 32,000) which contrasted with the much higher figure around 150,000 which was previously envisioned. Attempts to make a global assessment of the use of alternative splicing are recent and rely essentially on the comparison of genomic mRNA and EST sequences as reviewed by Thanaraj and Stamm in the first chapter of this volume. Most recent estimates suggest that 40-60% of human genes might be alternatively spliced, as opposed to about 22% for C. elegans.

Download or read book Examination of the Coupling of Transcription to Pre mRNA Processing written by Barbara June Natalizio and published by . This book was released on 2008 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eukaryotic precursor messenger RNA s (pre-mRNAs) are exclusively synthesized by RNA polymerase II (RNAP II) and require extensive processing for maturation into functional mRNAs. RNAP II transcription is coupled to pre-mRNA processing by mechanisms that are not well understood. In order to elucidate the mechanisms that mediate the functional coupling of transcription to pre-mRNA processing, we established an in vitro system capable of transcribing and splicing complex transcripts. Using this system, we observed that transcripts synthesized by RNAP II are spliced more efficiently than the same transcripts synthesized by T7 RNA polymerase (T7 RNAP). Furthermore, we demonstrated that this system could be used as a method to study alternative splicing.

Download or read book Investigating the Cotranscriptional Regulation of Pre mRNA Splicing and 3 end Processing microform written by Emanuel Rosonina and published by National Library of Canada = Bibliothèque nationale du Canada. This book was released on 2004 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transcriptional activators play an important role in the assembly of the transcriptional apparatus at the promoter regions of genes. We examined whether activators participate in the coupling of transcription with pre-mRNA processing, as well. Strong activation domains resulted in higher levels of splicing and cleavage compared to weak activation domains when targeted to the promoter of reporter genes. Truncation of the CTD abrogated this effect indicating that the CTD is involved in mediating the effect of strong activators on efficient processing. Further exploration of this mechanism revealed that splicing factor PSF binds preferentially to strong activation domains, and stimulates splicing and cleavage in vivo, in a CTD dependent manner. Therefore, PSF likely mediates the effect of a strong activator on efficient processing, whereby strong activators facilitate the association of PSF with the elongation apparatus. Our findings therefore implicate both transcriptional activators and PSF in cotranscriptional splicing and 3 '-end formation. The production of a messenger RNA (mRNA) is a complex process that involves many concerted steps, including the processing of the primary transcript, or precursor mRNA (pre-mRNA). Processing involves capping, 3' -end cleavage and polyadenylation, and splicing of introns from within the pre-mRNA. Pre-mRNAs are transcribed by RNA polymerase II (pol II), and it has been found that pre-mRNA processing is coupled to transcription by pol II, facilitating efficient and coordinated production of mature mRNA. Here I report the results of investigations of cotranscriptional splicing and 3'-end formation of pre-mRNAs. The carboxyl-terminal domain (CTD) of pol II is a highly-repetitive sequence unique to pol II that plays key roles in coupling gene expression events leading to the production of mRNA. We examined the CTD requirement for processing of different pre-mRNAs by exploring the effect of CTD mutations on splicing and cleavage of reporter genes in mammalian cells. We found that the length, rather than the type of CTD repeats, can be the major determinant in the efficient processing of pre-mRNA substrates. Furthermore, our results suggest that the requirement for the CTD in pre-mRNA processing is dependent on sequences within the gene itself. The degree of CTD-dependence therefore appears to be pre-mRNA specific.

This book was released on 2008-02-05 with total page 277 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 Molecular Biology of RNA written by David Elliott and published by Oxford University Press. This book was released on 2017-01-31 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: RNA plays a central, and until recently, somewhat underestimated role in the genetics underlying all forms of life on earth. This versatile molecule not only plays a crucial part in the synthesis of proteins from a DNA template, but is also intrinsically involved in the regulation of gene expression, and can even act as a catalyst in the form of a ribozyme. This latter property has led to the hypothesis that RNA - rather than DNA - could have played an essential part in the origin of life itself. This landmark text provides a systematic overview of the exciting and rapidly moving field of RNA biology. Key pioneering experiments, which provided the underlying evidence for what we now know, are described throughout, while the relevance of the subject to human disease is highlighted via frequent boxes. For the second edition of Molecular Biology of RNA, more introductory material has been incorporated at the beginning of the text, to aid students studying the subject for the first time. Throughout the text, new material has been included - particularly in relation to RNA binding domains, non-coding RNAs, and the connection between RNA biology and epigenetics. Finally, a new closing chapter discusses how exciting new technologies are being used to explore current topical areas of research.
