    Cryo-EM structure of the SAGA and NuA4 coactivator subunit Tra1 at 3.7 angstrom resolution

    Luis Miguel Díaz-Santín, Natasha Lukoyanova ... Alan CM Cheung
    An atomic model of the 3744-residue Tra1 protein reveals multiple transcription activator binding sites, its integration within the SAGA chromatin coactivator complex, and a striking similarity to DNA-repair factor DNA-PKcs.

    Structural basis for interdomain communication in SHIP2 providing high phosphatase activity

    Johanne Le Coq, Marta Camacho-Artacho ... Daniel Lietha
    The SHIP2 inositol phosphatase is an important upstream regulator of the Akt signaling pathway, which requires a catalytic core formed by the phosphatase domain tightly packed to a C2 domain for its function.

    A novel region in the CaV2.1 α1 subunit C-terminus regulates fast synaptic vesicle fusion and vesicle docking at the mammalian presynaptic active zone

    Matthias Lübbert, R Oliver Goral ... Samuel M Young Jr
    A novel region in the CaV2.1 α1 subunit regulates coupling of synaptic vesicles to CaV2.1 calcium channels, synaptic vesicle release and docking, and the size of the fast and total releasable pools of synaptic vesicles.

    Structural insights into the light-driven auto-assembly process of the water-oxidizing Mn4CaO5-cluster in photosystem II

    Miao Zhang, Martin Bommer ... Athina Zouni
    The structures of photosystem II, with the water-oxidizing Mn4CaO5-cluster fully removed and in an intermediate assembly state, show that photoassembly is facilitated by perfectly pre-arranged protein ligands of the five metal ions.

    Structural insight into the activation of a class B G-protein-coupled receptor by peptide hormones in live human cells

    Lisa Seidel, Barbara Zarzycka ... Irene Coin
    Agonist and antagonist peptides of the corticotropin-releasing factor receptor type 1 adopt different folds and stabilize distinct conformations of the receptor transmembrane domain, which involves tilting of helices VI and VII around conserved glycine hinges.

    Deconstruction of the Ras switching cycle through saturation mutagenesis

    Pradeep Bandaru, Neel H Shah ... John Kuriyan
    Sequence conservation in Ras depends strongly on the biochemical network in which it operates, providing a framework for understanding the origin of global selection pressures on proteins.

    Two-step membrane binding by the bacterial SRP receptor enable efficient and accurate Co-translational protein targeting

    Yu-Hsien Hwang Fu, William Y C Huang ... Shu-ou Shan
    Single molecule microscopy combined with biochemical analyses show that a two-step lipid-binding mechanism of the SRP receptor balances the trade-off between speed and specificity during co-translational protein targeting.
