(Submitter supplied) Acetylation of histone H3 at residue K9 (H3K9ac) is a dynamically regulated mark associated with transcriptionally active promoters in eukaryotes. However, our understanding of the relation-ship between H3K9ac and gene expression remains largely correlative. In this study, we identify a large suite of growth-related genes in yeast that undergo a particularly strong down-regulation of both transcription and H3K9ac upon stress, and delineate the roles of transcriptional activa-tors, repressors, SAGA histone acetyltransferase, and RNA-polymerase II in this response. more...

(Submitter supplied) The populational variance of eukaryotic transcription differs by gene, and can be range from constitutive to bursty in nature. Exemplary bursty yeast genes tend to rely on SAGA and Mediator Tail (coactivator-redundant, CR) for transcription, and often contain TATA boxes in their promoters. To dissect gene-specific transcriptional bursting and the roles of coactivator complexes in regulating bursting in yeast, we performed genome-wide nascent single-cell RNA-seq. more...

(Submitter supplied) The main decay pathway of yeast mRNAs in the cytoplasm uses the 5’-3’ exonuclease Xrn1. This protein shuttles from the cytoplasm to the nucleus, where it has a role as transcription factor. We have recently demonstrated that importing depends on two nuclear localization sequences (NLS 1 & NLS2) and that exporting depends on its binding (presumably co-transcriptional) to mRNAs. It is also known that Xrn1 is able to degrade decapped mRNAs that are still being translated by ribosomes. more...

(Submitter supplied) H3K4 methylation is a conserved histone modification crucial for gene regulation, yet the post-translational modifications of the Set1-COMPASS complex remain largely unexplored. This study elucidates the significance of N-terminal acetylation in modulating H3K4 methylation patterns. Firstly, loss of NatA complex resulted in a significant decrease in H3K4me3 levels and a shift of H3K4me2 from 5' transcribed regions to promoters. more...

(Submitter supplied) Transcription coupled-nucleotide excision repair (TC-NER) repairs DNA lesions that stall RNA polymerase II (Pol II) transcription. Here, we show that the C-terminal domain (CTD) of elongation factor-1 (Elf1) plays a critical role in TC-NER in yeast. Analysis of genome-wide repair of UV-induced cyclobutane pyrimidine dimers (CPDs) using CPD-seq indicates that the Elf1 CTD is required for efficient Rad26-dependent and Rad26-independent TC-NER across the yeast genome. more...

(Submitter supplied) How parental histone H3-H4 tetramers, the primary carrier of epigenetic modifications, are transferred to leading and lagging strands of DNA replication forks following DNA replication is an important question that remains not well understood. Here we show that DNA polymerase clamp PCNA and its partner involved in lagging strand DNA synthesis, Pol d, regulate parental histone transfer to lagging strands. more...

(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...
