    The autophagy adaptor NDP52 and the FIP200 coiled-coil allosterically activate ULK1 complex membrane recruitment

    Xiaoshan Shi, Chunmei Chang ... James H Hurley
    Hydrogen-deuterium exchange, electron microscopy, and vesicle reconstitution show how binding of the autophagy adaptor NDP52 to the FIP200 subunit of the ULK1 complex triggers membrane binding in autophagy.

    The P2X7 receptor forms a dye-permeable pore independent of its intracellular domain but dependent on membrane lipid composition

    Akira Karasawa, Kevin Michalski ... Toshimitsu Kawate
    Functional reconstitution of a mammalian P2X7 receptor uncovers an intrinsic and lipid-dependent dye-permeable membrane pore.

    Analysis of the mechanosensor channel functionality of TACAN

    Yiming Niu, Xiao Tao ... Roderick MacKinnon
    Electrophysiological and structural data do not support a mechanosensitive channel function for TACAN.

    Molecular dissection of PI3Kβ synergistic activation by receptor tyrosine kinases, GβGγ, and Rho-family GTPases

    Benjamin R Duewell, Naomi E Wilson ... Scott D Hansen
    Single molecule reconstitution of PI3Kβ synergistic activation reveals mechanism for rapid PI(3,4,5)P3 production during immune cell signaling.

    Control of lipid domain organization by a biomimetic contractile actomyosin cortex

    Sven Kenjiro Vogel, Ferdinand Greiss ... Petra Schwille
    Building on previous work (Vogel et al., 2013b), it is shown that myosin-driven actin filament rearrangements actively move, split or fuse individual lipid domains and change their overall shape.

    Dwarf open reading frame (DWORF) is a direct activator of the sarcoplasmic reticulum calcium pump SERCA

    M'Lynn E Fisher, Elisa Bovo ... Howard S Young
    Activation of the sarcoplasmic reticulum calcium pump and enhancement of cellular calcium homeostasis by dwarf open reading frame reveal how this small membrane protein opposes phospholamban inhibitory function in cardiac muscle.

    Symmetry breaking in reconstituted actin cortices

    Enas Abu Shah, Kinneret Keren
    A reconstituted system has been developed that self-organizes into dynamic actin cortices capable of spontaneous polarization, similar to the initial cortical polarization observed in cells during embryogenesis and development.

    The role of sigma 1 receptor in organization of endoplasmic reticulum signaling microdomains

    Vladimir Zhemkov, Jonathon A Ditlev ... Ilya Bezprozvanny
    Signaling function of sigma 1 receptor is related to its ability to organize cholesterol-enriched microdomains in the endoplasmic reticulum membrane.

    Structure of Escherichia coli respiratory complex I reconstituted into lipid nanodiscs reveals an uncoupled conformation

    Piotr Kolata, Rouslan G Efremov
    The dynamic structure of respiratory complex I from mesophilic bacterium is revealed and demonstrates existence of uncoupled conformations in the bacterial complex.

    The neuronal calcium sensor Synaptotagmin-1 and SNARE proteins cooperate to dilate fusion pores

    Zhenyong Wu, Nadiv Dharan ... Erdem Karatekin
    During neurotransmitter release, calcium-induced membrane insertion of the C2B domain of Synaptotagmin re-orients the bound SNARE complex which dilates the fusion pore in a mechanical lever action.
