(Submitter supplied) In yeast Saccharomyces cerevisiae, there are two translation termination factors, eRF1 (SUP45) and eRF3 (SUP35), which are essential for viability. Previous studies have revealed that presence of nonsense mutations in these genes leads to amplification of mutant alleles (sup35-n and sup45-n) which appears to be necessary for viability of such cells. However, the mechanism of this phenomenon remained unclear. more...

(Submitter supplied) Arabidopsis gene expression is regulated by more than 1,900 transcription factors (TFs), which have been identified genome-wide by the presence of well-conserved DNA binding domains. Activator TFs contain activation domains (ADs) that recruit coactivator complexes; however, for most Arabidopsis TFs, we lack knowledge about the presence, location, and transcriptional strength of their ADs. To address this gap, we experimentally identified Arabidopsis ADs on a proteome-wide scale, finding that over half of Arabidopsis TFs carry an AD. more...

(Submitter supplied) Eukaryotes employ a set of conserved transcription elongation factors to modulate the behavior of RNA polymerase II (RNAPII). Disruptions of one such factor, the Paf1 complex (Paf1C), generate subunit-specific phenotypes, including distinct changes to co-transcriptional histone modifications. How individual Paf1C subunits impact transcription and coupled processes remains ambiguous. By comparing conditional depletion and steady-state deletion of Paf1C subunits, we determine direct and indirect contributions of Paf1C to gene expression in Saccharomyces cerevisiae. more...

(Submitter supplied) The goal of this study was to test the effect of metal cations (CaCl2 and MnCl2) during Pol II NET-seq. These metals are readily used in the majority of studies that use NET-seq to analyze Pol II occupancy, but their effect on nascent transcript capture has not been analyzed. Our results suggest that the inclusion of these metals in Pol II NET-seq experiments does not cause a significant change in Pol II occupancy in the untreated control vs. more...

(Submitter supplied) Protein folding is driven by the burial of hydrophobic amino acids in a tightly-packed core that excludes water. The genetics, biophysics and evolution of hydrophobic cores are not well understood, in part because of a lack of systematic experimental data on sequence combinations that do - and do not - constitute stable and functional cores. Here we randomize protein hydrophobic cores and evaluate their stability and function at scale. more...

(Submitter supplied) Proteins function in crowded cellular environments in which they must bind to specific target proteins but also avoid binding to many other off-target proteins. In large protein families this task is particularly challenging because many off-target proteins have very similar structures. How this specificity of physical protein-protein interactions in cellular networks is encoded and evolves is not very well understood. more...

(Submitter supplied) Reprogramming a non-methylotrophic industrial host, such as Saccharomyces cerevisiae, to a synthetic methylotroph reprents a huge challenge due to the complex regulation in yeast. Through TMC strategy together with ALE strategy, we completed a strict synthetic methylotrophic yeast that could use methanol as the sole carbon source. However, how cells respond to methanol and remodel cellular metabolic network on methanol were not clear. more...

(Submitter supplied) Aneuploidy has a myriad of consequences for health and disease, yet models of aneuploidy toxicity are still widely debated. To distinguish the effects of specific genes from the generalized burden of chromosome amplification, we measured the effects of duplicating individual genes in euploid cells as well as in select aneuploids using a barcoded plasmid library. We analyzed the responses of cells with and without extra chromosomes, as well as those with and without RNA-binding protein Ssd1. more...

To uncover the consequences of peroxisome deficiency, we compared two extremes, namely Saccharomyces cerevisiae wild-type and pex3 cells, which lack functional peroxisomes, employing transcriptomics and quantitative proteomics technology. more...

(Submitter supplied) Pre-mRNA splicing is vital for the proper function and regulation of eukaryotic gene expression. Saccharomyces cerevisiae has been used as a model organism for studies of RNA splicing because of the striking conservation of the spliceosome and its catalytic activity. Nonetheless, there are relatively few annotated alternative splice forms, particularly when compared to higher eukaryotes. Here, we describe a method to combine large scale RNA sequencing data to accurately discover novel splice isoforms in Saccharomyces cerevisiae. more...

(Submitter supplied) mRNAs are transcribed and processed in the nucleus before they are exported into the cytoplasm for translation. Export is mediated by the export receptor heterodimer Mex67-Mtr2 in yeast (TAP-p15 in humans). Interestingly, also many lncRNAs leave the nucleus but it is currently unclear why they travel into the cytoplasm. Here we show that antisense (as)RNAs accelerate mRNA export by annealing with their sense counterparts through the helicase Dbp2. more...

Export is mediated by the export receptor heterodimer Mex67-Mtr2 in yeast (TAP-p10 in humans).

Tens of millions of missense variants exist in the current human population, with the vast majority having unknown functional consequences.

Using DNA synthesis and cellular selection experiments we quantify the impact of >500,000 variants on the abundance of >500 human protein domains. more...

(Submitter supplied) Enzymes catalyze the reactions of life and are the targets of nearly all small molecule drugs. Most drugs inhibit enzymes by binding to conserved active sites, causing problems of specificity and toxicity. Targeting regulatory allosteric sites can increase specificity, overcome drug resistance and tune or activate activity.However, the vast majority of enzymes have no known allosteric sites and methods do not exist to globally identify or predict them.Here we present a general and fast method to globally chart allosteric communication in enzymes and apply it to the Src protein kinase to produce the first comprehensive map of negative and positive allosteric control of enzymatic activity. more...

(Submitter supplied) Stress-induced condensation of mRNA and proteins into stress granules is conserved across eukaryotes, yet the function, formation mechanisms, and relation to well-studied conserved transcriptional responses remain largely unresolved. Stress-induced exposure of ribosome-free mRNA following translational shutoff is thought to cause condensation by allowing new multivalent RNA-dependent interactions, with RNA length and associated interaction capacity driving increased condensation. more...

How affinity and specificity are encoded in these binding domains and the motifs themselves is not well understood. The evolvability of binding specificity - how rapidly and extensively it can change upon mutation - is also largely unexplored, as is the contribution of ‘fuzzy’ dynamic residues to affinity and specificity in protein-protein interactions. more...
