    Direct assessment of substrate binding to the Neurotransmitter:Sodium Symporter LeuT by solid state NMR

    Simon Erlendsson, Kamil Gotfryd ... Claus J Loland
    Solid state NMR is unable to detect any association of substrate to the second binding site, S2, in the extracellular vestibule of the Neurotransmitter:Sodium Symporter LeuT.

    Structural basis for allosteric control of the SERCA-Phospholamban membrane complex by Ca2+ and phosphorylation

    Daniel K Weber, U Venkateswara Reddy ... Gianluigi Veglia
    A spectroscopic analysis of the sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA)-phospholamban membrane complex reveals the importance of the relative transmembrane orientation for inhibition or activation of the ATPase.

    Mg2+-dependent conformational equilibria in CorA and an integrated view on transport regulation

    Nicolai Tidemand Johansen, Marta Bonaccorsi ... Lise Arleth
    The Mg2+-channel CorA explores a wide conformational landscape of non-conducting states irrespective of bound Mg2+, but only in abscence of Mg2+, conducting states become accessible due to increased backbone dynamics.

    Membrane curvature sensing and symmetry breaking of the M2 proton channel from Influenza A

    James Lincoff, Cole VM Helsell ... Michael Grabe
    Using a combination of all-atom molecular simulation and continuum membrane mechanics, M2 channels from influenza are shown to be stabilized in negative Gaussian curvature regions, such as the neck of budding viral particles, only in C2-symmetric conformations.

    Constitutive activation and oncogenicity are mediated by loss of helical structure at the cytosolic boundary of thrombopoietin receptor mutant dimers

    Jean-Philippe Defour, Emilie Leroy ... Stefan N Constantinescu
    Structural and functional analyses reveal the general mechanism of activation of the thrombopoietin receptor and unravel the critical role of W515.

    BNP facilitates NMB-encoded histaminergic itch via NPRC-NMBR crosstalk

    Qing-Tao Meng, Xian-Yu Liu ... Zhou-Feng Chen
    B-type natriuretic peptide (BNP) modulates itch via BNP-NPRC pathway by enhancing NMB-NMBR signaling, which is independently of gastrin-releasing peptide (GRP)-GRPR signaling in the spinal cord.

    Inducing conformational preference of the membrane protein transporter EmrE through conservative mutations

    Maureen Leninger, Ampon Sae Her, Nathaniel J Traaseth
    Conservative mutations within a secondary active transport protein influenced the conformational equilibrium probed using NMR spectroscopy which correlated to the functional output in vivo.

    The intrinsically disordered cytoplasmic tail of a dendrite branching receptor uses two distinct mechanisms to regulate the actin cytoskeleton

    Daniel A Kramer, Heidy Y Narvaez-Ortiz ... Baoyu Chen
    The dendrite branching receptor HPO-30 modulates actin dynamics by binding to both WAVE complex and actin filaments.

    Diameter dependence of transport through nuclear pore complex mimics studied using optical nanopores

    Nils Klughammer, Anders Barth ... Cees Dekker
    Nuclear pore complex mimics based on solid-state nanopores show significant selectivity below a diameter of 55 nm, which decreases gradually for larger pore diameters.

    Cryo-EM structure of alpha-synuclein fibrils

    Ricardo Guerrero-Ferreira, Nicholas MI Taylor ... Henning Stahlberg
    The alpha-synuclein fibril structure reported here buries residues 50-57 at the interface between its two protofilaments, suggesting that familial Parkinson's disease associated mutations in these residues lead to a structure not compatible with the one presented here.
