A ribosome assembly stress response regulates transcription to maintain proteome homeostasis

(Submitter supplied) Ribosome biogenesis is a complex and energy-demanding process requiring tight coordination of ribosomal RNA (rRNA) and ribosomal protein (RP) production. Alteration of any step in this process may impact growth by leading to proteotoxic stress. Although the transcription factor Hsf1 has emerged as a central regulator of proteostasis, how its activity is coordinated with ribosome biogenesis is unknown. more...

Proteotoxicity from aberrant ribosome biogenesis compromises cell fitness

(Submitter supplied) To achieve maximal growth, cells must manage a massive economy of ribosomal proteins (r-proteins) and RNAs (rRNAs) to produce thousands of ribosomes every minute. Although ribosomes are essential in all cells, natural disruptions to ribosome biogenesis lead to heterogeneous phenotypes. Here, we model these perturbations in Saccharomyces cerevisiae and show that challenges to ribosome biogenesis result in acute loss of proteostasis. more...

Cytosolic splice isoform of Hsp70 nucleotide exchange factor Fes1 is required for the degradation of misfolded proteins in yeast

(Submitter supplied) Cells maintain proteostasis by selectively recognizing and targeting misfolded proteins for degradation. In Saccharomyces cerevisiae, the Hsp70 nucleotide exchange factor Fes1 is essential for the degradation of chaperone-associated misfolded proteins by the ubiquitin-proteasome system. Here we show that the FES1 transcript undergoes unique 3' alternative splicing that results in two equally active isoforms with alternative C-termini, Fes1L and Fes1S. more...

Determination of the nascent transcriptional rates in a TEToff::ARB1 conditional mutant.

(Submitter supplied) Transcription of eukaryotic genes involves dynamic interactions between RNA polymerases and chromatin that are facilitated by auxiliary factors. One of these chromatin factors is Spt6, encoded by an essential gene that plays regulatory functions throughout all eukaryotes, from yeast to human. We have performed a genetic analysis of Spt6 function by isolating yeast mutations that confer synthetic-lethality to a conditional spt6 allele under permissive conditions. more...

Genome-wide Ifh1p occupancy at the OX growth phase and RC quiescent phase of the yeast metabolic cycle

(Submitter supplied) We found ribosomal transcription factor Ifh1p is dynamically acetylated and phosphorylated in response to nutrient cues. ChIP-seq data revealed dynamic binding to ribosomal genes (RP) during the OX growth phase of the yeast metabolic cycle (YMC) when RP genes are highly induced, and weaker binding in the RC quiescent-like phase. Besides RP genes, our ChIP-seq data also reveals binding of Ifh1p to non-RP genes such as translation factors and metabolic genes.

Yeast heat shock response at 37C, 42C and 46C

(Submitter supplied) Life is resilient because living systems are able to respond to elevated temperatures with an ancient gene expression program called the heat shock response (HSR). Our global analysis revealed a modular HSR dependent on the severity of the stress in yeast. Interestingly, at all temperatures analyzed, the transcription of hundreds of genes is upregulated among them the molecular chaperones, which protect proteins from aggregation. more...

Aneuploidy-induced proteotoxic stress can be effectively tolerated without dosage compensation, genetic mutations or stress responses

(Submitter supplied) The protein homeostasis (proteostasis) network maintains balanced protein synthesis, folding, transport and degradation within a cell. Because failure to maintain proteostasis is associated with aging and disease, a concerted effort has been placed on studying how the proteostasis network responds to various stresses. Typically, this is accomplished using ectopic overexpression of well-characterized, model misfolded protein substrates; however, how cells tolerate large-scale, diverse burden to the proteostasis network is not understood. more...

Defining the Essential Function of Yeast Hsf1 Reveals a Compact Transcriptional Program for Maintaining Eukaryotic Proteostasis

(Submitter supplied) We used the conditional chemical genetics approach known as “anchor away” (AA) to rapidly inactivate the essential yeast transcription factor Hsf1. We coupled Hsf1-AA to RNA-seq and NET-seq to define the genes whose expression depends on Hsf1 and performed Hsf1-3xFLAG-V5 ChIP-seq to validate direct targets. We also carried out a number of other perturbations to yeast stress pathways to show that most of the gene expression changes during heat shock are Hsf1-independent but depend on PKA signaling and the Msn2/4 general stress transcription factors. more...

ADH1 deletion cells upon growth on alternative carbon sources; Steady-state grown cells upon environmental perturbations

(Submitter supplied) Cells must adjust their gene expression in order to compete in a constantly changing environment. Two alternative strategies could in principle ensure optimal coordination of gene expression with physiological requirement. First, the internal physiological state itself could feedback to regulated gene expression. Second, the expected physiological state could be inferred from the external environment, using evolutionary-tuned signaling pathways. more...

Genome-wide location analysis of Abf1 and Reb1 in Saccharomyces cerevisiae

(Submitter supplied) Abf1 and Reb1, two general regulatory factors playing roles at promoters and other genome functional sites in budding yeast, were mapped genome-wide by ChIP-sequencing using strains expressing TAP-tagged versions of the proteins. As expected on the basis of previous in silico analysis of promoter regions, we found that these factors are enriched at the promoters of ribosome biogenesis (Ribi) genes, a large regulon of more than 200 genes required for ribosome biosynthesis and assembly, and known to be coordinately regulated in response to nutrient availability and cellular growth rate.

Sch9 regulates ribosome biogenesis via Stb3, Dot6 and Tod6 and the histone deacetylase complex RPD3L (ChIP-Seq data)

(Submitter supplied) TORC1 is a structurally and functionally conserved multiprotein complex that regulates many aspects of eukaryote growth including the synthesis and assembly of ribosomes. The protein kinase activity of this complex is responsive to environmental cues and is potently inhibited by the natural product macrolide rapamycin. Insights into how TORC1 regulates growth have been provided with the recent identification of the rapamycin-sensitive phosphoproteome in yeast. more...

Affy data from WT, FHL1 deleted and FHL1,IFH1 double deleted strains.

(Submitter supplied) Affymetrix experiment performed on RNA isolated from Wild type, FHL1 deleted and FHL1,IFH1 double deleted strains. Data aquired in duplicate. In S. cerevisiae the mRNAs from the 138 ribosomal protein (RP) genes are amongst the most abundant in the cell, and their transcription is regulated tightly so that they are the most prominent cluster in most transcriptome experiments. It has recently been observed that the proteins Fhl1p and Ifh1p are found almost exclusively at RP genes (Lee et al., Science, 298, 799-804, 2002;Jorgensen et al., Genes Dev, 18, 2491-2505 2004; Schawalder et al Nature in press; Rudra et al , EMBO J. more...
