This book was released on 2007 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Both retroviruses and cellular genes rely on post-transcriptional mechanisms to regulate the timing and abundance of their protein product. The post-transcriptional control element (PCE) has been identified in the 5' untranslated regions of mRNAs from selected retroviruses and the cellular gene JunD. PCE containing mRNAs rely on the DExH/D box helicase RNA helicase A (RHA) to specifically facilitate robust synthesis of their protein product. Study of retroviruses has developed approaches to understand both cellular control of gene expression and the dyregulation that contributes to cancer and immunodeficiency. JunD, a member of the activator protein -1 (AP-1) family of transcription factors, is important for transcriptional regulation of growth control genes. Dysregulation of JunD is implicated in cancer and metabolic disease via defects in cell- proliferation and disease-associated apoptosis and can also modulate viral persistence. Studies described here build on the previous characterization of SNV and JunD PCE function in HIV gag-pol reporter plasmids and investigate the parental SNV provirus. The results presented validate the role of PCE in combination with a newly identified a distal element, designated the I,II element, in regulation of balanced expression and translational utilization of SNV mRNA. A key conclusion is that PCE and the distal I,II element comprise a bipartite element that interacts with RNA helicase A to selectively modulate post-transcriptional expression of the unspliced SNV gag mRNA. This thesis also reviews the current and historical literature of JunD gene regulation. Three core areas are described and intriguing essential issues are discussed: i) transcription regulation by AP-1 complexes containing JunD protein, ii) post-translational modification of JunD by Jun-terminal kinase (Jnk) and protein:protein interactions, and iii) regulation of translation intiation by JunD PCE. Lessons learned from the study of retrovirus genes have produced essential knowledge of the JunD transcription factor and contributed to the characterization of a novel axis of transational control of complex RNAs.

Download or read book Recoding Expansion of Decoding Rules Enriches Gene Expression written by John F. Atkins and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: The literature on recoding is scattered, so this superb book ?lls a need by prov- ing up-to-date, comprehensive, authoritative reviews of the many kinds of recoding phenomena. Between 1961 and 1966 my colleagues and I deciphered the genetic code in Escherichia coli and showed that the genetic code is the same in E. coli, Xenopus laevis, and guinea pig tissues. These results showed that the code has been c- served during evolution and strongly suggested that the code appeared very early during biological evolution, that all forms of life on earth descended from a c- mon ancestor, and thus that all forms of life on this planet are related to one another. The problem of biological time was solved by encoding information in DNA and retrieving the information for each new generation, for it is easier to make a new organism than it is to repair an aging, malfunctioning one. Subsequently, small modi?cations of the standard genetic code were found in certain organisms and in mitochondria. Mitochondrial DNA only encodes about 10–13 proteins, so some modi?cations of the genetic code are tolerated that pr- ably would be lethal if applied to the thousands of kinds of proteins encoded by genomic DNA.
Download or read book HIV 1 Integrase written by Nouri Neamati and published by John Wiley & Sons. This book was released on 2011-08-10 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively covers the mechanisms of action and inhibitor design for HIV-1 integrase. It serves as a resource for scientists facing challenging drug design issues and researchers in antiviral drug discovery. Despite numerous review articles and isolated book chapters dealing with HIV-1 integrase, there has not been a single source for those working to devise anti-AIDS drugs against this promising target. But this book fills that gap and offers a valuable introduction to the field for the interdisciplinary scientists who will need to work together to design drugs that target HIV-1 integrase.
Download or read book Translational Control of Gene Expression written by Nahum Sonenberg and published by CSHL Press. This book was released on 2001 with total page 1034 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1996 publication of Translational Control, there has been fresh interest in protein synthesis and recognition of the key role of translation control mechanisms in regulating gene expression. This new monograph updates and expands the scope of the earlier book but it also takes a fresh look at the field. In a new format, the first eight chapters provide broad overviews, while each of the additional twenty-eight has a focus on a research topic of more specific interest. The result is a thoroughly up-to-date account of initiation, elongation, and termination of translation, control mechanisms in development in response to extracellular stimuli, and the effects on the translation machinery of virus infection and disease. This book is essential reading for students entering the field and an invaluable resource for investigators of gene expression and its control.

Available in PDF, EPUB and Kindle. Book excerpt: This volume, part of the Advances in Molecular Biology series, presents work by pioneers in the field and is the first publication devoted solely to the yeast two-hybrid system. It includes detailed protocols, practical advice on troubleshooting, and suggestions for future development. In addition, it illustrates how to construct an activation domain hybrid library, how to identify mutations that disrupt an interaction, and how to use the system in mammalian cells. Many of the contributors have developed new applications and variations of the technique.

Download or read book Foamy Viruses written by Axel Rethwilm and published by Springer Science & Business Media. This book was released on 2003-05-12 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aberrant replication pathway of foamy viruses distinguishes them from all other retroviruses. Many details have been accumulated over the past ten or so years. Most of the findings on foamy viruses were obtained by research on a single virus isolate previously called "human foamy virus", which appeared to be the first to be investigated on a molecular level. However, to the editor's knowledge, genuine human foamy viruses do not exist, but several trans-species transmissions of different simian foamy viruses from monkeys and apes to human hosts.

Download or read book Cell Polarity and Subcellular RNA Localization written by Dietmar Richter and published by Springer Science & Business Media. This book was released on 2012-11-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selective cytoplasmic organelle and protein targeting has long been thought to constitute the sole determinant of cell polarity and complexity. This view has been changed, however, by the discovery of differential subcellular RNA distribution patterns. Over the past decade it has become clear that selective mRNA sorting and translation contributes to an accumulation of cognate proteins at discrete cellular sites. In this book, various systems are discussed (e.g. Xenopus oocytes, mammalian brain, invertebrate nervous system) in terms of RNA trafficking, RNA-targeting sequences (cis-elements) and RNA-transporting proteins (trans-factors), activity-dependent translational regulation and the significance of the cytoskeleton for neuronal function and plasticity. It also discusses nucleocytoplasmic export of mRNA and viral RNA as another example of subcellular RNA kinesis.
