    Efficient protein targeting to the inner nuclear membrane requires Atlastin-dependent maintenance of ER topology

    Sumit Pawar, Rosemarie Ungricht ... Ulrike Kutay
    Efficient targeting of membrane proteins from the endoplasmic reticulum (ER) to the inner nuclear membrane depends on GTP hydrolysis by Atlastin GTPases and their function in maintaining an interconnected topology of the ER network.

    Multiple selection filters ensure accurate tail-anchored membrane protein targeting

    Meera Rao, Voytek Okreglak ... Shu-ou Shan
    Biochemical dissections show that the Guided Entry of Tail Anchored proteins (GET) pathway selects ER-destined tail-anchored proteins using at least two distinct molecular mechanisms, each recognizing a distinct physicochemical feature in the substrate.

    ER-associated mitochondrial division links the distribution of mitochondria and mitochondrial DNA in yeast

    Andrew Murley, Laura L Lackner ... Jodi Nunnari
    Sites at which mitochondria contact the endoplasmic reticulum co-localize the replication of mitochondria and their DNA to help ensure that DNA is distributed appropriately between the newly formed organelles in cells.

    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.

    Unconventional secretory processing diversifies neuronal ion channel properties

    Cyril Hanus, Helene Geptin ... Erin M Schuman
    Imaging, quantitative immunoblotting and mass spectrometry reveal that hundreds of surface-expressed neuronal membrane proteins exhibit atypical glycosylation profiles, resulting in changes in protein half-life and synaptic responses.

    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.

    Membrane characteristics tune activities of endosomal and autophagic human VPS34 complexes

    Yohei Ohashi, Shirley Tremel ... Roger L Williams
    The lipid kinase VPS34 complexes I and II are both activated by unsaturation of substrate and non-substrate lipids, curvature, electrostatics and polyphosphoinositides, which play roles in localisation and cellular function.

    Proteomic mapping of cytosol-facing outer mitochondrial and ER membranes in living human cells by proximity biotinylation

    Victoria Hung, Stephanie S Lam ... Alice Y Ting
    One minute biotinylation with APEX2 peroxidase in living cells identifies established and new components of mitochondrial and ER membranes; dataset intersection and overexpression screen identifies SYNJ2BP overexpression as inducing mitochondria-rough ER contacts.

    Src activates retrograde membrane traffic through phosphorylation of GBF1

    Joanne Chia, Shyi-Chyi Wang ... Frederic A Bard
    Src phosphorylates GBF1, promoting binding of the Sec7 domain to Arf1 and the formation of GALNTs containing tubules emanating from the Golgi.

    An ER phospholipid hydrolase drives ER-associated mitochondrial constriction for fission and fusion

    Tricia T Nguyen, Gia K Voeltz
    ABHD16A is a phospholipid-modifying endoplasmic reticulum (ER) membrane protein required for both mitochondrial fission and fusion machinery recruitment to ER-associated mitochondrial constrictions.
