Download or read book Characterizing the Role of Gds1p in the Saccharomyces Cerevisiae Environmental Stress Response written by Mihai-Vlad Cotrut and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The transcription factors Msn2p and Msn4p are major components of the Saccharomyces cerevisiae environmental stress response. Their transient activation/deactivation is dependent on a regulatory network centering on nucleocytoplasmic shuttling but also includes a range of other mechanisms. The acetyltransferase complex, NuA4 has been implicated in repression of Msn2p yet the mechanism is largely unknown. Gds1p is an uncharacterized yeast protein identified in a recent study as a physical interactor and acetylation target of NuA4. Gds1 protein level is dependant both on NuA4 and environmental stress and our analysis shows it to be involved in the nuclear exclusion of Msn2p in the absence of stress. Unstressed cells lacking GDS1 exhibit increased nuclear accumulation Msn2p and an increase in transcription of the stress reporter gene, HSP12. My work supports a model in which Gds1 and NuA4 can work independently to inhibit the Msn2/4 dependant yeast stress response in the absence of stress.
Download or read book Elucidation of Novel Components of the Response to Genotoxic Stress in Saccharomyces Cerevisiae written by Bryan M. O'Neill and published by . This book was released on 2007 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Faithful maintenance of genome integrity is essential for cellular viability. Failure to efficiently recognize and repair DNA damage or respond to replication stress can lead to genomic instability and, in higher eukaryotes, cancer. The cellular response to genotoxic stress has been particularly well characterized in Saccharomyces cerevisiae through the isolation of mutants that are hypersensitive to specific agents that cause DNA damage and/or replication stress. However, there is still much about this response that is not yet known, including many of the actual components. The work described in this dissertation was driven by a desire to improve our knowledge of this area. We used high-throughput genomic and proteomic screening approaches to identify novel genes and proteins that mediate the genotoxic stress response. From these experiments, we isolated Wss1, which is required for an efficient response to UV irradiation and replication stress. We believe Wss1 may contribute to survival by stabilizing or processing stalled or collapsed replication forks. As a result of the investigation of WSS1, we also isolated PSY2 as a gene required for viability following treatment with the DNA damaging agent MMS. Further study revealed that Psy2 partners with the phosphatase Pph3 to regulate the cell cycle checkpoint response. In addition to our efforts into the general response, we also pursued the identification of genes that when inactivated, attenuate the cells ability to mutate. From this effort, we identified two genes, FYV6 and RNR4, that function in novel pathways that induce mutagenesis in response to UV irradiation. Together, these studies illustrate that the tools available in the post-genomic era provide opportunities for novel insights into the response to genotoxic stress at a rapid pace.

Download or read book Non Conventional Yeasts in Genetics Biochemistry and Biotechnology written by Klaus Wolf and published by Springer Science & Business Media. This book was released on 2003-03-04 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most information on yeasts derives from experiments with the conventional yeasts Saccaromyces cerevisiae and Schizossaccharomyces pombe, the complete nuclear and mitochondrial genome of which has also been sequenced. For all other non-conventional yeasts, investigations are in progress and the rapid development of molecular techniques has allowed an insight also into a variety of non-conventional yeasts. In this bench manual, over 70 practical protocols using 15 different non-conventional yeast species and in addition several protocols of general use are described in detail. All of these experiments on the genetics, biochemistry and biotechnology of yeasts have been contributed by renowned laboratories and have been reproduced many times. The reliable protocols are thus ideally suited also for undergraduate and graduate practical courses.

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 The Perfect Slime written by Hans-Curt Flemming and published by IWA Publishing. This book was released on 2016-09-15 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Perfect Slime presents the latest state of knowledge and all aspects of the Extracellular Polymeric Substances, (EPS) matrix – from the ecological and health to the antifouling perspectives. The book brings together all the current material in order to expand our understanding of the functions, properties and characteristics of the matrix as well as the possibilities to strengthen or weaken it. The EPS matrix represents the immediate environment in which biofilm organisms live. From their point of view, this matrix has paramount advantages. It allows them to stay together for extended periods and form synergistic microconsortia, it retains extracellular enzymes and turns the matrix into an external digestion system and it is a universal recycling yard, it protects them against desiccation, it allows for intense communication and represents a huge genetic archive. They can remodel their matrix, break free and eventually, they can use it as a nutrient source. The EPS matrix can be considered as one of the emergent properties of biofilms and are a major reason for the success of this form of life. Nevertheless, they have been termed the “black matter of biofilms” for good reasons. First of all: the isolation methods define the results. In most cases, only water soluble EPS components are investigated; insoluble ones such as cellulose or amyloids are much less included. In particular in environmental biofilms with many species, it is difficult to impossible isolate, separate the various EPS molecules they are encased in and to define which species produced which EPS. The regulation and the factors which trigger or inhibit EPS production are still very poorly understood. Furthermore: bacteria are not the only microorganisms to produce EPS. Archaea, Fungi and algae can also form EPS. This book investigates the questions, What is their composition, function, dynamics and regulation? What do they all have in common?
