    Membrane insertion of α-xenorhabdolysin in near-atomic detail

    Evelyn Schubert et al.
    Cryo-EM and X-ray structures of α-xenorhabdolysin in soluble and pore form of Xenorhabdus nematophila give novel insights into the mechanism of action of bi-component α-pore-forming toxins.

    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.

    Aurora-A mediated histone H3 phosphorylation of threonine 118 controls condensin I and cohesin occupancy in mitosis

    Candice L Wike et al.
    A histone modification that alters the nucleosome structure occurs in mitosis and promotes chromosome packaging and the timely removal of condensin I and cohesion, to achieve chromosome segregation.

    Novel mechanism of metabolic co-regulation coordinates the biosynthesis of secondary metabolites in Pseudomonas protegens

    Qing Yan et al.
    The production of two secondary metabolites is co-regulated in a bacterium via an intermediate in one pathway that is converted into signals to activate the second pathway.

    A sphingolipid-dependent diffusion barrier confines ER stress to the yeast mother cell

    Lori Clay et al.
    Sphingolipids govern the compartmentalization of yeast cells through the assembly of lateral diffusion barriers in ER membranes.

    Daple is a novel non-receptor GEF required for trimeric G protein activation in Wnt signaling

    Nicolas Aznar et al.
    Daple is a guanine nucleotide-exchange factor (GEF) for trimeric G proteins that enables Wnt/Frizzled receptors to transactivate G proteins during non-canonical Wnt signaling.

    Natural variation in sugar tolerance associates with changes in signaling and mitochondrial ribosome biogenesis

    Richard G Melvin et al.
    The optimal macronutrient composition, macronutrient space, varies strongly between closely related species and is determined by genetic changes in regulatory genes that globally reprogram gene expression profiles of metabolic pathways.

    A genetically defined asymmetry underlies the inhibitory control of flexor–extensor locomotor movements

    Olivier Britz et al.
    Two classes of premotor inhibitory neurons have specific roles in controlling flexor-extensor behaviors in mice, which is the underlying neural mechanism for limb driven movements in terrestrial vertebrates.

    Heat stress promotes longevity in budding yeast by relaxing the confinement of age-promoting factors in the mother cell

    Sandro Baldi et al.
    To promote longevity under heat stress shares yeast aging factors with progeny through a down-regulation of the diffusion barrier in the membranes between the mitotic cells.

    Synthetic single domain antibodies for the conformational trapping of membrane proteins

    Iwan Zimmermann et al.
    Synthetic single domain antibody libraries and a binder selection cascade encompassing ribosome and phage display enable the selection of conformation-specific binders against previously intractable membrane proteins within three weeks.
