    The step-wise pathway of septin hetero-octamer assembly in budding yeast

    Andrew Weems, Michael McMurray
    In budding yeast cells, slow monomeric septin GTPase activity and the cytosolic GTP:GDP ratio dictate the relative incorporation of alternative subunits during septin hetero-oligomer assembly, which proceeds by discrete, ordered steps dependent on allostery between interaction interfaces.

    Intraneural stimulation elicits discrimination of textural features by artificial fingertip in intact and amputee humans

    Calogero Maria Oddo et al.
    Delivering specific patterns of electrical activity to the median nerve of the arm triggers reliable sensations of texture, suggesting that it may ultimately be possible to restore complex tactile information to users of prosthetic limbs.

    Snf1/AMPK promotes the formation of Kog1/Raptor-bodies to increase the activation threshold of TORC1 in budding yeast

    James E Hughes Hallett et al.
    The key Target of Rapamycin Complex (TORC1) component Kog1 moves into bodies during glucose starvation to limit reactivation of the complex.

    Single-molecule tracking of the transcription cycle by sub-second RNA detection

    Zhengjian Zhang et al.
    A new technique called fastFISH enables nearly real-time and stoichiometric detection of nascent RNA and the tracking of individual stages of transcription at the level of single-molecules.

    How lamina-associated polypeptide 1 (LAP1) activates Torsin

    Brian A Sosa et al.
    LAP1 adopts an AAA+ like fold that, while unable to bind nucleotide, can enhance ATPase activity in the neighboring TorsinA protomer in an unusual heterohexameric ring, via an arginine finger.

    A putative ATPase mediates RNA transcription and capping in a dsRNA virus

    Xuekui Yu et al.
    Atomic structures suggest a novel mechanism for the regulation of mRNA transcription and capping in dsRNA viruses.

    Stochastic modelling, Bayesian inference, and new in vivo measurements elucidate the debated mtDNA bottleneck mechanism

    Iain G Johnston et al.
    New modelling, statistics, and experiments show that cellular populations of mitochondrial DNA (mtDNA) evolve during development according to solvable stochastic dynamics involving binomial partitioning and random turnover, facilitating a predictive and quantitative theory of the mtDNA bottleneck.

    FACT and Ubp10 collaborate to modulate H2B deubiquitination and nucleosome dynamics

    Melesse Nune et al.
    The histone chaperone FACT and the deubiquitinating enzyme Ubp10 act in concert to remove ubiquitin from histone H2B in nucleosomes, and likely coordinate nucleosome assembly during DNA replication and transcription.

    Human cytomegalovirus IE1 protein alters the higher-order chromatin structure by targeting the acidic patch of the nucleosome

    Qianglin Fang et al.
    Distinct binding of viral proteins to the same region on the nucleosome surface can result in contrasting changes to higher-order chromatin structure in the host cell.

    A composite double-/single-stranded RNA-binding region in protein Prp3 supports tri-snRNP stability and splicing

    Sunbin Liu et al.
    Structural and functional analyses show how the spliceosomal Prp3 protein concomitantly binds double- and single- stranded regions in U4/U6 di-snRNAs and serves to stabilize the U4/U6•U5 tri-snRNP for splicing.
