    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.

    Biochemical basis for the regulation of biosynthesis of antiparasitics by bacterial hormones

    Iti Kapoor, Philip Olivares, Satish K Nair
    Biochemical and structural biological analyses show how bacteria can recognize hormones that control the production of important secondary metabolites such as antiparasitics and antibiotics.

    Skd3 (human ClpB) is a potent mitochondrial protein disaggregase that is inactivated by 3-methylglutaconic aciduria-linked mutations

    Ryan R Cupo, James Shorter
    Skd3 (human ClpB) is a potent ATP-dependent mitochondrial protein disaggregase that is activated by the rhomboid protease, PARL, and inactivated by MGCA7-linked mutations.

    Nucleosome-CHD4 chromatin remodeler structure maps human disease mutations

    Lucas Farnung, Moritz Ochmann, Patrick Cramer
    The structure of the chromatin remodeller CHD4 bound to a nucleosome reveals differences to the known Chd1-nucleosome complex and maps cancer mutations.

    AR phosphorylation and CHK2 kinase activity regulates IR-stabilized AR–CHK2 interaction and prostate cancer survival

    Huy Q Ta, Natalia Dworak ... Daniel Gioeli
    CHK2 directly binds the AR to mediate transient suppression of AR activity and thus loss of CHK2 function in prostate cancer increases AR activity, DNA damage response and radiation resistance.

    Activin A forms a non-signaling complex with ACVR1 and type II Activin/BMP receptors via its finger 2 tip loop

    Senem Aykul, Richard A Corpina ... Vincent Idone
    The non-signaling complex formed by Activin A and ACVR1 is operant in vivo and is required to temper the degree of heterotopic ossification in the genetic disorder fibrodysplasia ossificans progressiva.

    Membrane characteristics tune activities of endosomal and autophagic human VPS34 complexes

    Yohei Ohashi, Shirley Tremel ... Roger L Williams
    The lipid kinase VPS34 complexes I and II are both activated by unsaturation of substrate and non-substrate lipids, curvature, electrostatics and polyphosphoinositides, which play roles in localisation and cellular function.

    Synergy between SIRT1 and SIRT6 helps recognize DNA breaks and potentiates the DNA damage response and repair in humans and mice

    Fanbiao Meng, Minxian Qian ... Baohua Liu
    SIRT1 deacetylates SIRT6 at K33 to facilitate DNA double-strand breaks-recognition, subsequent expansion and local chromatin remodeling.
