    Molecular structures of the human Slo1 K+ channel in complex with β4

    Xiao Tao, Roderick MacKinnon
    The structures of Slo1 in complex with b4 imply that the auxiliary beta subunits modulate the channel's gating properties through stabilizing ‘pre-existing’ conformations rather than creating new ones.

    Structure of a mitochondrial ATP synthase with bound native cardiolipin

    Alexander Mühleip, Sarah E McComas, Alexey Amunts
    The atomic model of a mitochondrial ATP synthase dimer underlies functions of its specific protein constituents and boundary cardiolipins.

    Real time dynamics of Gating-Related conformational changes in CorA

    Martina Rangl, Nicolaus Schmandt ... Simon Scheuring
    High-speed atomic force microscopy reveals that the open state of the divalent ion channel CorA is highly dynamic and defined by the fast exchange between conformations.

    Molecular determinants of the Ska-Ndc80 interaction and their influence on microtubule tracking and force-coupling

    Pim J Huis in 't Veld, Vladimir A Volkov ... Marileen Dogterom
    Binding of two macromolecular complexes allows kinetochores to capture force produced by the depolymerising ends of microtubules, allowing chromosomes to be transmitted from a mother cell to its two daughters.

    De novo design of a homo-trimeric amantadine-binding protein

    Jooyoung Park, Brinda Selvaraj ... David Baker
    The first successful de novo design of a homo-trimeric protein that binds a C3 symmetric small molecule larger than a metal ion is an advance for computational protein design.

    Modulating FOXO3 transcriptional activity by small, DBD-binding molecules

    Judith Hagenbuchner, Veronika Obsilova ... Michael J Ausserlechner
    The mode of binding and cellular effect of the first FOXO3-DNA-binding-domain targeting small compound discovered by a combined pharmacophore-based/biochemical screening approach is reported.

    Mechanistic basis of the inhibition of SLC11/NRAMP-mediated metal ion transport by bis-isothiourea substituted compounds

    Cristina Manatschal, Jonai Pujol-Giménez ... Raimund Dutzler
    The structural and mechanistic characterization of competitive inhibition of human DMT1 offers a promising route for the development of compounds for the treatment of iron overload disorders.

    Multiple kinesins induce tension for smooth cargo transport

    Marco Tjioe, Saurabh Shukla ... Paul R Selvin
    After developing a force-gliding assay with nanometer and piconewton precision, it is concluded that multiple kinesins driving a single cargo induces tension, resulting in smooth cargo transport, even with roadblocks.

    Helix breaking transition in the S4 of HCN channel is critical for hyperpolarization-dependent gating

    Marina A Kasimova, Debanjan Tewari ... Baron Chanda
    The gating polarity of a voltage-gated ion channel is primarily determined by turn propensity of residues at a critical position in the middle of the S4 voltage-sensing helix.

    The HCN domain couples voltage gating and cAMP response in hyperpolarization-activated cyclic nucleotide-gated channels

    Alessandro Porro, Andrea Saponaro ... Anna Moroni
    Experimental and computational approaches reveal how ligand binding is coupled to voltage sensing in a HCN channels.
