(Submitter supplied) Transcriptional profiling of yeast strains (WT, rim15Δ, and igo1Δigo2Δ) treated with 100nM rapamycin at 20, 60, 120, 180min post treatment with respect to immediately before treatment as reference. Goal of the experiment was to test whether Rim15 and Igo1/2 are implicated in proper regulating of gene expression during nutrient limitation and TORC1 inhibition by rapamycin. At 180 minutes after rapamycin treatment, 478 genes were upregulated more than 2.8 fold in the wild-types cells; whereas the upregulation of 54 were diminished in rim15 mutant and upregulation of 103 genes diminished in cells lacking Igo1 and Igo2. more...

(Submitter supplied) To assess the role of the decapping activator Scd6 in mRNA decay, we used RNA-Seq to analyze the expression profile of yeast cells harboring a deletion of the SCD6 gene. Consistent with our recent model for decapping regulation, we found that Scd6 targets a small number of specific mRNAs in yeast cells. Interestingly, degradation of Scd6-targeted transcripts also requires the functions of the decapping activators Pat1, Lsm1, and Dhh1, suggesting that Scd6 functions together with Pat1, Lsm1, and Dhh1 in promoting mRNA decapping.

(Submitter supplied) To assess the roles of the Dcp2 C-terminal domain and the decapping activators Pat1, Lsm1, and Dhh1 in mRNA decapping, we used RNA-Seq to analyze the expression profiles of yeast cells harboring a truncation of the Dcp2 C-terminal domain, mutations that render Dcp2 catalytically inactive, or deletions of the PAT1, LSM1, and DHH1 genes. Consistent with our recent model for decapping regulation, we found that: i) the Dcp2 C-terminal domain is an effector of both negative and positive regulation and that loss of these control functions causes significant deregulation of mRNA decapping; ii) rather than being global activators of decapping, Pat1, Lsm1, and Dhh1 directly target specific subsets of yeast mRNAs and loss of the functions of each of these factors has substantial indirect consequences for genome-wide mRNA expression; and iii) transcripts targeted by Pat1, Lsm1, and Dhh1 exhibit only partial overlap and, as expected, are targeted to decapping-dependent decay.

(Submitter supplied) The Ccr4-Not complex is a major regulator of stress responses that controls gene expression at multiple levels, from transcription to mRNA decay. Ccr4, a core subunit of the complex, is the main cytoplasmic deadenylase in Saccharomyces cerevisiae, however its mRNA targets have not been mapped on a genome-wide scale. Here we describe a genome-wide approach, RNA immunoprecipitation-high throughput sequencing (RIP-seq), to identify the RNAs bound to Ccr4, and two proteins that associate with it, Dhh1 and Puf5. more...

(Submitter supplied) In budding yeast, the nuclear RNA surveillance system is active on all pre-mRNA transcripts and modulated by nutrient availability. To test the role of nuclear surveillance in reprograming gene expression, we identified transcriptome-wide binding sites for RNA polymerase II (Pol II) and the exosome cofactors Mtr4 (TRAMP complex) and Nab3 (NNS complex) by UV-crosslinking immediately following glucose withdrawal (0, 4, and 8 minutes). more...

(Submitter supplied) Degradation of most yeast mRNAs involves decapping by Dcp1/Dcp2. DEAD-box protein Dhh1 has been implicated as an activator of decapping, and as a translational repressor, but their functions in cells are incompletely understood. We have analyzed these questions by a combination of ribosome profiling, RNA-Seq, CAGE analysis of capped mRNAs.

(Submitter supplied) Yeast mRNA decapping-activators Pat1 and Dhh1 have been implicated in repressing translation and mRNA degardation in glucose-deprived cells, but the specific mRNAs targeted by each factor and their functions in nutrient replete cells are poorly understood. To test this, we performed ribosome profiling and RNA-Seq in WT, pat1D and pat1Ddhh1D. Further, CAGE-Seq and Rpb1-ChIP Seq were employed to determine their role in decapping mediated degradation of mRNAs

(Submitter supplied) Determination of 3' or 5' intragenic RNA pol II occupancy. Maintaining the proper mRNA levels is a key aspect in the regulation of gene expression. The balance between mRNA synthesis and decay determines these levels. Using a whole-genome analysis, we demonstrate that most yeast mRNAs are degraded by the 5'-to-3' pathway (the "decaysome"), as proposed previously. Unexpectedly, the level of these mRNAs is highly robust to perturbations in this major pathway, as defects in various decaysome components lead to transcription down-regulation. more...

(Submitter supplied) The budding yeast Saccharomyces cerevisiae alters its gene expression profile in response to a change in nutrient availability. The PHO-system is a well-studied case in the transcriptional regulation responding to nutritional changes in which a set of genes (PHO genes) is expressed to activate phosphate (Pi) metabolism for adaptation to Pi-starvation. Pi-starvation triggers an inhibition of Pho85 kinase, leading to migration of unphosphorylated Pho4 transcriptional activator into the nucleus enabling expression of PHO genes. more...

(Submitter supplied) DEAD-box RNA helicases eIF4A and Ded1 are believed to promote translation initiation by resolving mRNA secondary structures that impede ribosome attachment at the mRNA 5’ end or subsequent scanning of the 5’UTR, but whether they perform distinct functions or act redundantly in vivo is poorly understood. We compared the effects of mutations in Ded1 or eIF4A on global translational efficiencies (TEs) in yeast by ribosome footprint profiling. more...

(Submitter supplied) A universal feature of the response to stress and nutrient limitation is transcriptional upregulation of genes encoding proteins important for survival. Interestingly, under many of these conditions overall protein synthesis levels are reduced, thereby dampening the stress response at the level of protein expression. For example, during glucose starvation in yeast, translation is rapidly and reversibly repressed, yet transcription of many stress- and glucose-repressed genes is increased. more...
