    Antagonistic control of DDK binding to licensed replication origins by Mcm2 and Rad53

    Syafiq Abd Wahab, Dirk Remus
    The mechanism of Dbf4-dependent kinase (DDK) recruitment to replication origins and its regulation by the checkpoint have been identified.

    Peroxiredoxin promotes longevity and H2O2-resistance in yeast through redox-modulation of protein kinase A

    Friederike Roger, Cecilia Picazo ... Mikael Molin
    The major cytosolic yeast peroxiredoxin Tsa1 controls aging and H2O2-resistance by inhibiting protein kinase A through a conserved cysteine in the catalytic subunit activation loop and not by scavenging H2O2.

    Controlling protein function by fine-tuning conformational flexibility

    Sonja Schmid, Thorsten Hugel
    Specific and non-specific conformational confinement, via point mutation or cochaperone interaction or macro-molecular crowding, stimulates protein function in Hsp90 by reducing non-productive conformational flexibility.

    New insights into the mechanism of dynein motor regulation by lissencephaly-1

    Steven M Markus, Matthew G Marzo, Richard J McKenney
    The role of LIS1 in dynein-mediated transport in various biological contexts is reviewed with a focus on recent studies that revealed a new mechanism by which LIS1 functions.

    Changes in ferrous iron and glutathione promote ferroptosis and frailty in aging Caenorhabditis elegans

    Nicole L Jenkins, Simon A James ... Gawain McColl
    As worms age reduced glutathione together with increased ferrous iron increases frailty and leads to ferroptosis, which is amenable to therapeutic intervention.

    Emergence and diversification of a host-parasite RNA ecosystem through Darwinian evolution

    Taro Furubayashi, Kensuke Ueda ... Norikazu Ichihashi
    In an in vitro RNA replication system, an RNA spontaneously diversifies and continuously evolves through coevolution with parasitic entities.

    Tetramerisation of the CRISPR ring nuclease Crn3/Csx3 facilitates cyclic oligoadenylate cleavage

    Januka S Athukoralage, Stuart McQuarrie ... Malcolm F White
    A widespread ribonuclease is a CRISPR-associated ring nuclease with a highly unusual cooperative mechanism involving tetramerisation of the enzyme.

    Reconstitution reveals two paths of force transmission through the kinetochore

    Grace E Hamilton, Luke A Helgeson ... Trisha N Davis
    Two components of the inner kinetochore (OA and Mif2) are independently capable of transmitting physiologically relevant forces to a centromeric nucleosome.
