    Structural basis of dynamic P5CS filaments

    Jiale Zhong, Chen-Jun Guo ... Ji-Long Liu
    Cryo-electron microscopy structures of full-length P5CS, the proline synthesis enzyme, reveal that filamentation is crucial for the coordinated catalytic reactions between the glutamate kinase and γ-glutamyl phosphate reductase domains.

    Coil-to-α-helix transition at the Nup358-BicD2 interface activates BicD2 for dynein recruitment

    James M Gibson, Heying Cui ... Chunyu Wang
    A cargo recognition α-helix was identified in Nup358, which is required for activation of a dynein-dependent transport pathway that is essential for brain development.

    STIM1-dependent peripheral coupling governs the contractility of vascular smooth muscle cells

    Vivek Krishnan, Sher Ali ... Scott Earley
    STIM1 regulates the contractility of blood vessels and blood pressure by organizing membrane contact sites and ion channel activity in vascular smooth muscle cells in a manner that is independent of its canonical function in store-operated Ca2+entry.

    Ca2+ inactivation of the mammalian ryanodine receptor type 1 in a lipidic environment revealed by cryo-EM

    Ashok R Nayak, Montserrat Samsó
    Cryogenic electron microscopy of the ryanodine receptor 1 at near-atomic resolution reveals a calcium-inactivated conformation and uncovers a conserved lipid-binding site.

    A plasma membrane-localized polycystin-1/polycystin-2 complex in endothelial cells elicits vasodilation

    Charles E MacKay, Miranda Floen ... Jonathan H Jaggar
    Flow stimulates PC-1/PC-2 clusters in the plasma membrane of endothelial cells, leading to Ca2+ influx, NOS, SK channel, and IK channel activation, vasodilation, and a reduction in blood pressure.

    Structural dynamics determine voltage and pH gating in human voltage-gated proton channel

    Shuo Han, Sophia Peng ... Shizhen Wang
    Visualization of the real-time conformational transitions of the human voltage-gated proton channel hHv1 provided novel insights into how voltage and pH gradients modify the dynamic behaviors of channel structures to control proton flow across membrane.

    Structural basis for an unprecedented enzymatic alkylation in cylindrocyclophane biosynthesis

    Nathaniel R Braffman, Terry B Ruskoski ... Emily P Balskus
    The X-ray crystal structure of the unusual carbon–carbon bond-forming biosynthetic enzyme CylK reveals a unique biochemical strategy for selective alkyl halide activation and substitution.

    A saturation-mutagenesis analysis of the interplay between stability and activation in Ras

    Frank Hidalgo, Laura M Nocka ... John Kuriyan
    Deep mutagenesis experiments demonstrate that while cancer-causing mutations in Ras selectively alter regulatory interactions with GTPase-activating proteins, Ras is also activated by many mutations that decrease protein stability.

    Identification of electroporation sites in the complex lipid organization of the plasma membrane

    Lea Rems, Xinru Tang ... Lucie Delemotte
    Advanced data analysis of molecular dynamics simulations of complex lipid membranes provides a quantitative and predictive model of the molecular features that control electroporation.
