    PGAM5 promotes lasting FoxO activation after developmental mitochondrial stress and extends lifespan in Drosophila

    Martin Borch Jensen, Yanyan Qi ... Heinrich Jasper
    A signaling pathway involving PGAM5, ASK1 and JNK induces persistent FoxO activation, chaperone expression and lifespan extension following developmental mitochondrial stress, which can be blocked by mTOR signaling through GCN-2.

    Aneuploidy as a cause of impaired chromatin silencing and mating-type specification in budding yeast

    Wahid A Mulla, Chris W Seidel ... Rong Li
    Genetic analyses reveal that purely quantitative changes in the relative copy number of chromosomes can be sufficient to disrupt the epigenetic mechanisms that define the cells' differentiated state.

    Cooperative interactions enable singular olfactory receptor expression in mouse olfactory neurons

    Kevin Monahan, Ira Schieren ... Stavros Lomvardas
    Biochemical and genetic experiments show that Ebf and Lhx2 cooperate to specify olfactory receptor enhancers, which cooperate to drive olfactory receptor expression.

    ME31B globally represses maternal mRNAs by two distinct mechanisms during the Drosophila maternal-to-zygotic transition

    Miranda Wang, Michael Ly ... Olivia S Rissland
    ME31B is a general repressor of gene expression in the Drosophila early embryo, repressing translation before the maternal-to-zygotic transition and stimulating mRNA decay after activation of the zygotic genome.

    Transcription factor clusters regulate genes in eukaryotic cells

    Adam JM Wollman, Sviatlana Shashkova ... Mark C Leake
    Transcription factors form clusters independently of the presence of DNA, which regulate target genes as opposed to individual monomers, addressing a longstanding question of how transcription factors can find gene targets so quickly.

    Mcm10 promotes rapid isomerization of CMG-DNA for replisome bypass of lagging strand DNA blocks

    Lance D Langston, Ryan Mayle ... Mike E O'Donnell
    Biochemical data demonstrate an unexpected and critical function for the enigmatic Mcm10 protein in helping the eukaryotic CMG helicase/replisome bypass roadblocks on the DNA that may also explain Mcm10 function at origins of replication.

    A novel SH2 recognition mechanism recruits Spt6 to the doubly phosphorylated RNA polymerase II linker at sites of transcription

    Matthew A Sdano, James M Fulcher ... Christopher P Hill
    The tandem SH2 domains of Spt6 use novel mechanisms to bind unexpected phosphorylated serine and threonine residues in the RNA polymerase II linker to recruit Spt6 to sites of transcription and maintain repressive chromatin.

    A sharp Pif1-dependent threshold separates DNA double-strand breaks from critically short telomeres

    Jonathan Strecker, Sonia Stinus ... Daniel Durocher
    A sharp transition in the fate of DNA ends with telomere sequences is identified, which suggests a boundary between DNA double-strand breaks and telomeres.

    Cryo-EM structure of the SAGA and NuA4 coactivator subunit Tra1 at 3.7 angstrom resolution

    Luis Miguel Díaz-Santín, Natasha Lukoyanova ... Alan CM Cheung
    An atomic model of the 3744-residue Tra1 protein reveals multiple transcription activator binding sites, its integration within the SAGA chromatin coactivator complex, and a striking similarity to DNA-repair factor DNA-PKcs.

    In vitro analysis of RQC activities provides insights into the mechanism and function of CAT tailing

    Beatriz A Osuna, Conor J Howard ... David E Weinberg
    Yeast extracts recapitulate a quality-control pathway dedicated to rescuing stalled ribosomes, providing unexpected insights into a noncanonical elongation reaction and the fate of incompletely synthesized proteins.
