Download or read book Strain Dependent Differences in MAPK Signaling in Yeast written by Taylor Dean Scott and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: All cells must respond to extracellular signals in order to exist in a dynamic environment. Mitogen-activated protein kinase (MAPK), among the most common signaling networks, are found in all eukaryotes and are important for cancer biology, developmental biology, and the response to stress. The MAPK networks in the model organism Saccharomyces cerevisiae, commonly known as budding yeast, are a model system for studying signal transduction through MAPK networks, and particularly the mechanisms by which cells prevent signal from leaking into connected networks. In this thesis I study how the yeast strain background affects signal flow through MAPK networks and explore potential genetic causes of strain-dependent differences. I compare two strain backgrounds, YPH499 and [sigma]1278b (Sigma) side-by-side to determine the extent to which they differ in their response to osmostress and pheromone, which signal through the HOG and mating pathways respectively. I show that Sigma is more osmosensitive than YPH499 despite growing faster in ordinary, non-stress conditions. I further show that despite this increased osmosensitivity, Sigma is better able to respond to simultaneous osmostress and pheromone, showing a faster activation of the mating pathway after the delay caused by osmostress. I also demonstrate that, while the HOG and mating/FG pathways are insulated in YPH499 as has been previously reported, there is significant and transient leakage from the HOG pathway into the mating/FG pathways in the Sigma background, a phenomenon known as crosstalk. I then use a bulk segregant approach to map signaling differences to genetic loci or quantitative trait loci (QTL). I identified QTL for basal pFUS1-eGFP expression and crosstalk and tested genes within these QTL by introducing the allele from one parent into the opposite strain background. MAPK signaling is an important cellular process, and he large number of existing yeast strains provide a resource for exploring how modifications to a signaling network affect pathway output. My results demonstrate that the strain background greatly impacts signaling output, even in closely related laboratory strains, and establishes protocols for assaying signaling traits in closely related strains.

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 Fission Yeast written by Iain Hagan and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fission yeast are unicellular, rod-shaped fungi that divide by medial fission. Studies using fission yeast were instrumental in identifying fundamental mechanisms that govern cell division, differentiation, and epigenetics, to name but a few. Their rapid growth rate, genetic malleability, and similarities to more complex eukaryotes continue to make them excellent subjects for many biochemical, molecular, and cell biological studies. This laboratory manual provides an authoritative collection of core experimental procedures that underpin modern fission yeast research. The contributors describe basic methods for culturing and genetically manipulating fission yeast, synchronization strategies for probing the cell cycle, technologies for assessing proteins, metabolites, and cell wall constituents, imaging methods to visualize subcellular structures and dynamics, and protocols for investigating chromatin and nucleic acid metabolism. Modifications to techniques commonly used in related species (e.g., budding yeast) are noted, as are useful resources for fission yeast researchers, including various databases and repositories. The well-studied fission yeast Schizosaccharomyces pombe is the focus throughout, but the emerging model S. japonicus-a larger, dimorphic species with several desirable characteristics-is also covered. This manual is an important reference for existing fission yeast laboratories and will serve as an essential start-up guide for those working with fission yeast for the first time.
Download or read book The Septins written by Peter A. Hall and published by John Wiley & Sons. This book was released on 2008-11-20 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The authors represent most of the key figures and the work and the book as a whole is an essential reference for the newcomer or specialist in this area and for any student of eukaryotic cell structure and function. This is an important and wonderful reference." –Microbiology Today, May 2009 Septins are an evolutionarily conserved group of GTP-binding and filament-forming proteins that were originally discovered in yeast. Once the preserve of a small band of yeast biologists, the field has grown rapidly in the past few years and now encompasses the whole of animal and fungal biology. Furthermore, septins are nowadays recognized to be involved in a variety of disease processes from neoplasia to neurodegenerative conditions. This book comprehensively examines the septin gene family and their proteins, providing those new to this research area with a detailed and wide ranging introduction to septin biology. It starts with a unique historical perspective on the development of the field, from its beginnings in the screen for cell division mutants by the Nobel Laureate Lee Hartwell. The evolution of the septin gene family then forms a basis for consideration of the biochemistry and functions of septins in yeast and other model organisms including C. elegans and Drosophila. A major part of the book considers the diversity of septins in mammals, their functions and properties as well as their involvement in normal and abnormal cellular states, followed by a speculative overview from the editors of the key questions in septin research and of where the field may be headed. In addition, several appendices summarise important information for those in, or just entering, the field, e.g. nomenclature and septin and septin-like sequences. This book is an essential source of reference material for researchers in septin biology, cell biology, genetics and medicine, in particular pathology, including areas of neurobiology, oncology, infectious disease and developmental biology.
