    Single molecule imaging reveals a major role for diffusion in the exploration of ciliary space by signaling receptors

    Fan Ye, David K Breslow ... Maxence V Nachury
    Membrane receptor proteins move through primary cilia largely by passive diffusion rather than by active intraflagellar transport.

    The ER–Golgi intermediate compartment is a key membrane source for the LC3 lipidation step of autophagosome biogenesis

    Liang Ge, David Melville ... Randy Schekman
    A cell-free biochemical assay for protein lipidation identifies the ER–Golgi intermediate compartment as a key early station in the formation of an autophagosome.

    Minor introns are embedded molecular switches regulated by highly unstable U6atac snRNA

    Ihab Younis, Kimberly Dittmar ... Gideon Dreyfuss
    Hundreds of cell growth and stress response genes are controlled by a rare small RNA component of an ancient splicing machinery, providing a raison d'être for its previously unexplained evolutionary conservation.

    Dynamin phosphorylation controls optimization of endocytosis for brief action potential bursts

    Moritz Armbruster, Mirko Messa ... Timothy A Ryan
    The recycling of transmitter vesicles at synapses shows calcium-dependent regulation that depends on the phosphorylation status of an enzyme called dynamin.

    Direct live imaging of cell–cell protein transfer by transient outer membrane fusion in Myxococcus xanthus

    Adrien Ducret, Betty Fleuchot ... Tâm Mignot
    Physical contact between two Myxococcus xanthus cells is sufficient to fuse their outer membrane transiently and exchange outer membrane proteins and lipids at high efficiency.

    An essential and NSF independent role for α-SNAP in store-operated calcium entry

    Yong Miao, Cathrine Miner ... Monika Vig
    α-SNAP mediated rearrangement of Stim1 and Orai1 molecules within CRAC channel clusters is required for store-operated calcium entry.

    Apical targeting of the formin Diaphanous in Drosophila tubular epithelia

    Tal Rousso, Annette M Shewan ... Ben-Zion Shilo
    Synergistic interactions with PI(4,5)P2 and activated Rho1, which are enriched at the apical membrane of tubular organs, facilitate tight apical targeting of the formin Diaphanous.

    Hypothemycin, a fungal natural product, identifies therapeutic targets in Trypanosoma brucei

    Mari Nishino, Jonathan W Choy ... Jack Taunton
    Hypothemycin, which inhibits a number of protein kinases, kills the T. brucei parasites that cause sleeping sickness and reveals new therapeutic targets for the disorder.
