This book was released on 2015 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autophagy is the cellular mechanism of recruitment and decay of cytoplasmic molecules, proteins, and organelles that are obsolete for a particular growth condition. Autophagic degradation is distinct from proteasomal degradation by the formation of a de-novo double membrane which engulfs its cargo to be delivered for degradation to the yeast vacuole. Once thought to be only a general phenomenon of bulk decay, several autophagic pathways have demonstrated selectivity. In the following work we show that during nitrogen starvation (a potent inducer of autophagy) in the yeast Saccharomyces cerevisiae, a subset of translation factors are degraded selectively and rapidly. We go on to show that their efficient decay is dependent on a ubiquitin deubiquitinase, Ubp3p. Furthermore, we show that the proteasomal pathway is activated during nitrogen starvation and through which the selective degradation of the mRNA decay factors Dcp2p and Pop2p occurs. Interestingly, the decay of these latter factors are also dependent on Ubp3p. Ubp3p is also degraded during nitrogen starvation; we postulate as an auto-regulatory mechanism to inhibit the complete destruction of the selected proteins. Previous work in the autophagy field indicated that the mRNA of ATG8 was rapidly increased during nitrogen starvation. Since Atg8p is important for autophagosome biogenesis and expansion we sought a link between ATG8 increase and Dcp2p's decay. Our findings indicate that the 5'->3' mRNA decay pathway regulates autophagy during log growth by selectively degrading ATG8 mRNA. Furthermore, the proteasomal decay of Dcp2p coincides with an increase in ATG8 mRNA half-life during nitrogen starvation. This work has uncovered a novel mechanism of autophagic regulation that may be used to modulate autophagy to influence therapeutic outcomes.

Download or read book Identification and Characterization of Novel Proteins and Pathways for MRNA Degradation and Quality Control in Saccharomyces Cerevisiae written by and published by . This book was released on 2006 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: In eukaryotes, mRNA decay pathways are important for cellular response to various physiological conditions and also function in co-translational quality control systems that target translationally aberrant mRNAs for degradation. My work on identification and characterization of novel components and pathways of mRNA degradation and quality control in Saccharomyces cerevisiae is summarized below. I have identified Edc3p as a novel protein important for mRNA decay. Deletion of Edc3p leads to a defect in mRNA decay in strains deficient in decapping enzymes and, in combination with a block to the 3' to 5' decay pathway, causes exaggerated growth defects and synthetic lethality. An Edc3p-GFP fusion protein localizes in processing bodies, which are specialized cytoplasmic foci containing decapping proteins. Together, these observations indicate that Edc3p directly interacts with the decapping complex to stimulate the mRNA decapping rate. Quality control during mRNA translation is critical for regulation of gene expression. My work shows that yeast mRNAs with defects in translation elongation, due to strong translational pauses, are recognized and targeted for degradation via an endonucleolytic cleavage in a novel process referred to as No-Go Decay (NGD). The cellular mRNA decay machinery degrades the 5' and 3' cleavage products produced by NGD. NGD is translation-dependent, occurs in a range of mRNAs and can be induced by a variety of elongation pauses. These results indicate NGD may occur at some rate inresponse to any stalled ribosome. I also show that two highly conserved proteins, Dom34p and Hbs1p, homologous to the eukaryotic release factors eRF1 and eRF3 respectively, are required for NGD. Further characterization of the No-Go decay pathway indicates that Dom34p function during NGD is conserved across species. Identification of RPS30, a small ribosomal protein as a trans-acting factor during NGD suggests that the ribosome may have a novel role during NGD. Other experiments indicate that the No-Go decay pathway may cross talk with the unfolded protein response pathway. The identification of No-Go decay as a novel quality control pathway during translation elongation supports the existence of a global cellular mechanism for maintenance of translational quality control.
Book Synopsis The Control of Gene Expression by Nuclear RNA Degradation in Saccharomyces Cerevisiae by : Kevin Richard Jones Roy
Download or read book The Control of Gene Expression by Nuclear RNA Degradation in Saccharomyces Cerevisiae written by Kevin Richard Jones Roy and published by . This book was released on 2015 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ribonucleases play critical roles in controlling the quantity and quality of gene expression through processing and degrading RNA. An important class of evolutionarily conserved ribonucleases is the RNase III family of enzymes, which are distinguished by their specificity for cleaving double-stranded RNA (dsRNA). RNase III enzymes perform diverse functions in RNA metabolism in all eukaryotes studied, yet numerous questions remain regarding their range of natural targets in vivo, how they achieve substrate specificity, and how their cleavage activity is regulated. The model eukaryote Saccharomyces cerevisiae harbors one RNase III homolog, Rnt1p, which is responsible for all known dsRNA cleavage activity in this organism. To better understand the substrate selectivity of Rnt1p, we examined how its double-stranded RNA binding domain (dsRBD) recognizes a non-canonical substrate containing an AAGU tetraloop sequence differing from the NGNN consensus sequence. Surprisingly, we found that upon engaging the RNA, the dsRBD induces a structural change in the AAGU loop so that it closely adopts the structure of the NGNN loop. This suggested that the structures of isolated RNAs in solution are not necessarily predictive of substrate specificity. We next characterized how structural dynamics in the dsRBD mediate specific binding. We found that in order to bind substrate dsRNA with high affinity, the dsRBD must undergo a significant conformational change involving the first alpha helix and beta strand of the dsRBD. Next we implemented computational RNA secondary structure screens to scan the genome for potential Rnt1p targets. We identified a characteristic Rnt1p stem-loop in the BDF2 mRNA, which is also subject to nuclear decay by the spliceosome through a first step splicing discard pathway. Cis acting mutations in BDF2 blocking Rnt1p or spliceosome-mediated decay (SMD) conferred distinct phenotypes for each pathway, revealing that salt stress hyper-activates Rnt1p cleavage while spliceosome-mediated decay controls BDF2 expression during DNA replication stress. To globally identify RNA targets of Rnt1p cleavage, we leveraged the fact that the 5 product of Rnt1p cleavage is oligo-adenylated by Trf4/5-Air2/1-Mtr4 polyadenylation (TRAMP) complex prior to degradation by the nuclear exosome, a 3 -to-5 exonuclease complex. We mapped TRAMP poly(A) tails genome-wide by high-throughput sequencing of 3 ends of polyadenylated RNA in yeast cells lacking a nuclear exosome component. This revealed a global profile of destabilized 3 ends arising from various nuclear RNA degradation mechanisms, including Rnt1p cleavage, transcription termination by the Nrd1p-Nab3p-Sen1p (NNS) pathway and roadblock transcription termination by Reb1p and TFIIIB DNA binding factors. While the NNS pathway was known to play a prominent role in limiting pervasive RNA polymerase II, we uncovered previously unappreciated roles for roadblocks and Rnt1p in controlling Pol II transcriptional output throughout the genome, revealing how cells use a multitude of nuclear mechanisms to regulate the levels of coding and cryptic transcripts.
Book Synopsis Regulation of MRNA Decay in Saccharomyces Cerevisiae by the Sequence-specific RNA-binding Protein Vts1 by : Laura Marie Rendl
Download or read book Regulation of MRNA Decay in Saccharomyces Cerevisiae by the Sequence-specific RNA-binding Protein Vts1 written by Laura Marie Rendl and published by . This book was released on 2009 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vts1 is a member of the Smaug protein family, a group of sequence-specific RNA-binding proteins that regulate mRNA translation and degradation by binding to consensus stem-loop structures in target mRNAs. Using RNA reporters that recapitulate Vts1-mediated decay in vivo as well as endogenous mRNA transcripts, I show that Vts1 regulates the degradation of target mRNAs in Saccharomyces cerevisiae. In Chapter Two, I focus on the mechanism of Vts1-mediated mRNA decay. I demonstrate that Vts1 initiates mRNA degradation through deadenylation mediated by the Ccr4-Pop2-Not deadenylase complex. I also show that Vts1 interacts with the Ccr4-Pop2-Not deadenylase complex suggesting that Vts1 recruits the deadenylase machinery to target mRNAs, resulting in transcript decay. Following poly(A) tail removal, Vts1 target transcripts are decapped and subsequently degraded by the 5'-to-3' exonuclease Xrn1. Taken together these data suggest a mechanism of mRNA degradation that involves recruitment of the Ccr4-Pop2-Not deadenylase to target mRNAs. Previous work in Drosophila melanogaster demonstrated that Smg interacts with the Ccr4-Pop2-Not complex to regulate mRNA stability, suggesting Smaug family members employ a conserved mechanism of mRNA decay.In Drosophila, Smg also regulates mRNA translation through a separate mechanism involving the eIF4E-binding protein Cup. In Chapter Three, I identify the eIF4E-associated protein Eap1 as a component of Vts1-mediated mRNA decay in yeast. Interestingly Cup and Eap1 share no significant homology outside of the seven amino acid eIF4E-binding motif. In eap1Delta cells mRNAs accumulate as deadenylated capped species, suggesting that Eap1 stimulates mRNA decapping. I demonstrate that the Eap1 eIF4E-binding motif is required for efficient degradation of Vts1 target mRNAs and that this motif enables Eap1 to mediate an interaction between Vts1 and eIF4E. Together these data suggest Vts1 influences multiple steps in the mRNA decay pathway through interactions with the Ccr4-Pop2-Not deadenylase and the decapping activator Eap1.

This book was released on 2016 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: We searched through gene expression databases for long 3' UTR mRNAs that are targeted for degradation by the cytoplasmic mRNA degradation pathway, nonsense-mediated mRNA decay (NMD) (Sayani et al., 2008). This pathway, known for degrading mRNAs containing premature translation termination codons, also targets mRNAs with long 3'UTRs. We focused on the RTR1 locus which produces mRNAs with two prominent 3'UTR isoforms; the longer of which is targeted by the NMD system. We found from an RNA-seq data set that the RTR1 locus also produces a long non-coding RNA, known as a XUT, which is overlapping and antisense to the 3'UTR (van Dijk et al., 2011). We hypothesized that the XUT may form double-stranded RNA segments with the target mRNA 3'UTR and thus may stabilize the target mRNA. Our pursuit of this hypothesis was spurred by the result that early termination of the 3'UTR antisense XUT, which eliminates overlap between the RTR1 3'UTR and the antisense XUT, decreased the overall RTR1 mRNA steady-state abundance. We pursued a model for the regulation of target mRNAs by 3'UTR antisense XUTs whereby the XUT may compete with an RNA binding protein (RBP) that binds the 3'UTR and facilitates degradation of the mRNA. Ultimately, we invalidated this model by showing that the early termination of the antisense XUT does not result in a change in the half-life of RTR1 mRNAs compared to the wildtype strain upon transcription shut-off, and thus, the mutation must affect the mRNA abundance through changing the rate of transcription. In testing this model, however, we found an RBP site in the 3'UTR of RTR1 revealed by previously published genome-wide PAR-CLIP analysis of all RBP sites in the yeast genome (Freeberg et al., 2013). Deletion of this 3'UTR cis element led to an overall increase in abundance and stability of the RTR1 mRNAs. While deletion of known and well-characterized RBPs did not show an increase in RTR1 mRNA abundance, deletion of the RTR1 gene resulted in an increase in the abundance of an mRNA containing the RTR1 3'UTR that was also epistatic to the deletion of the cis element. This result led to the undertaking of a new study into the role of Rtr1p in mRNA decay that culminated in the manuscript presented in the second chapter of this dissertation. A key finding in this work was that mRNAs containing the Rtr1p cis element are targeted to a novel degradation pathway involving the 5'-3' RNA helicase, Dhh1p, and REX exonucleases. Because degradation of mRNAs constitutes a previously unrecognized role for the REX exonucleases, we followed up on this study by analyzing the impact of deleting the REX exonucleases on the transcriptome by RNA-seq. We present this RNA-seq analysis in Chapter 3 and further explore other cellular functions and mechanisms of Rex2p and Rex3p by performing affinity purification and mass-spectrometry sequencing of the interacting proteins. Our results show that Rex2p and Rex3p interact with the histone acetylase complex, SAGA, and this interaction may be important in the regulation of ribosomal protein genes (RPGs). Our transcriptome analysis of the REX mutants also reveals a possible role in the quality control of splicing. Overall, this work defines new substrates for the REX exonucleases and establishes a new function for this family of exonucleases in the regulation and quality control of gene expression via mRNA degradation.

Book Synopsis Molecular Mechanisms in Yeast Carbon Metabolism by : Jure Piškur
Download or read book Molecular Mechanisms in Yeast Carbon Metabolism written by Jure Piškur and published by Springer. This book was released on 2014-05-06 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yeast is one of the most studied laboratory organisms and represents one of the most central models to understand how any eukaryote cell works. On the other hand, yeast fermentations have for millennia provided us with a variety of biotech products, like wine, beer, vitamins, and recently also with pharmaceutically active heterologous products and biofuels. A central biochemical activity in the yeast cell is the metabolism of carbon compounds, providing energy for the whole cell, and precursors for any of the final fermentation products. A complex set of genes and regulatory pathways controls the metabolism of carbon compounds, from nutrient sensing, signal transduction, transcription regulation and post-transcriptional events. Recent advances in comparative genomics and development of post-genomic tools have provided further insights into the network of genes and enzymes, and molecular mechanisms which are responsible for a balanced metabolism of carbon compounds in the yeast cell, and which could be manipulated in the laboratory to increase the yield and quality of yeast biotech products. This book provides a dozen of most comprehensive reviews on the recent developments and achievements in the field of yeast carbon metabolism, from academic studies on gene expression to biotechnology relevant topics.

Book Synopsis Ubiquitin and the Biology of the Cell by : Jan-Michael Peters
Download or read book Ubiquitin and the Biology of the Cell written by Jan-Michael Peters and published by Springer Science & Business Media. This book was released on 1998-05-31 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last several years have been a landmark period in the ubiquitin field. The breadth of ubiquitin's roles in cell biology was first sketched, and the importance of ubiquitin-dependent proteolysis as a regulatory mechanism gained general acceptance. The many strands of work that led to this new perception are re counted in this book. A consequence of this progress is that the field has grown dramatically since the first book on ubiquitin was published almost a decade ago [M. Rechsteiner (ed. ), Ubiquitin, Plenum Press, 1988]. In this span, students of the cell cycle, transcription, signal transduction, protein sorting, neuropathology, cancer, virology, and immunology have attempted to chart the role of ubi quit in in their particular experimental systems, and this integration of the field into cell biology as a whole continues at a remarkable pace. We hope that for active researchers in the field as well as for newcomers and those on the fence, this book will prove helpful for its breadth, historical perspective, and practical tips. Structural data are now available on many of the components of the ubiquitin pathway. The structures have provided basic insights into the unusual biochemical mechanisms of ubiquitination and proteasome-mediated proteolysis. Because high-speed computer graphics can convey structures more effectively than print media, we have supplemented the figures of the book with a Worldwide Web site that can display the structures in a flexible, viewer-controlled format.
