    Single-molecule analysis of the entire perfringolysin O pore formation pathway

    Conall McGuinness, James C Walsh ... Till Böcking
    Arc-shaped PFO oligomers consisting of at least four subunits can insert into the membrane in a kinetically controlled process opening a transmembrane pore, whereby post-insertion growth may ultimately lead to formation of a complete ring.

    Analysis of the PcrA-RNA polymerase complex reveals a helicase interaction motif and a role for PcrA/UvrD helicase in the suppression of R-loops

    Inigo Urrutia-Irazabal, James R Ault ... Mark S Dillingham
    RNA polymerase recruits the PcrA DNA helicase via a conserved interaction motif in order to remove R-loops and prevent conflicts with replication.

    Thermal fluctuations of immature SOD1 lead to separate folding and misfolding pathways

    Ashok Sekhar, Jessica AO Rumfeldt ... Lewis E Kay
    Solution NMR spectroscopy reveals the energy landscape of immature Cu, Zn-superoxide dismutase and leads to atomic resolution structural models of transiently populated non-native oligomers.

    Structure of the human ATM kinase and mechanism of Nbs1 binding

    Christopher Warren, Nikola P Pavletich
    Structures of the human ataxia-telangiectasia mutated (ATM) kinase alone and bound to the C-terminus of Nbs1 show the mechanisms underlying ATM autoinhibition and binding by a portion of the Mre11-Rad50-Nbs1 (MRN) activating complex.

    Modulation of dopamine D1 receptors via histamine H3 receptors is a novel therapeutic target for Huntington's disease

    David Moreno-Delgado, Mar Puigdellívol ... Peter J McCormick
    Progression of Huntington's disease can be slowed by altering dopamine signalling through the Dopamine 1 receptor - Histamine 3 receptor heteromer.
