Riassunto
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.
Dalla quarta di copertina
mRNA processing is a key step in gene expression that effects all the proteins within the cell. In mRNA Processing and Metabolism: Methods and Protocols, world-renowned researchers bring together the latest techniques spanning the breadth of mRNA processing and metabolism. Drawing on recent advances in microscopy, whole genome sequencing, microarrays, mass spectrometry, fluorescent detection methodologies, and RNA interference, the authors offer readily reproducible methods for the cotranscriptional processing events that occur while the mRNA is engaged with elongating RNA polymerase II, with splicing and its biochemical analysis and with alternative splicing. Additional methods cover mRNA export, the recovery and analysis of mRNP complexes, cytoplasmic translation, mRNA degradation in vivo and in vitro, and the controversial concept of nuclear translation. A variety of model organisms are used, including yeast, Drosophila, Xenopus, mice, plants, and cultured mammalian cells. Each proven protocol is described in step-by-step detail and contains an introduction outlining the principle behind the technique, lists of equipment and reagents, and tips on troubleshooting and avoiding known pitfalls.
Timely and authoritative, mRNA Processing and Metabolism: Methods and Protocols provides a powerful collection of novel techniques that are not only effective, but also immediately applicable to current problems in many areas of biological research.
