    ER assembly of SNARE complexes mediating formation of partitioning membrane in Arabidopsis cytokinesis

    Matthias Karnahl, Misoon Park ... Gerd Jürgens
    SNARE proteins are delivered as complexes already from the endoplasmic reticulum along the secretory pathway to the cell division plane to mediate the formation of the partitioning membrane by vesicle fusion.

    Phosphorylation of iRhom2 at the plasma membrane controls mammalian TACE-dependent inflammatory and growth factor signalling

    Adam Graham Grieve, Hongmei Xu ... Matthew Freeman
    The iRhom2 protein, a catalytically inactive relative of rhomboid proteases, controls inflammation and growth factor signalling by acting as an essential multifunctional regulatory subunit of the cell surface shedding protease TACE (ADAM17).

    Protein Phosphatase 1 inactivates Mps1 to ensure efficient Spindle Assembly Checkpoint silencing

    Margarida Moura, Mariana Osswald ... Carlos Conde
    Inactivation of the master mitotic checkpoint regulator Mps1 by protein phosphatase 1 is required for timely segregation of the genetic material during cell division.

    Continuous transport of a small fraction of plasma membrane cholesterol to endoplasmic reticulum regulates total cellular cholesterol

    Rodney Elwood Infante, Arun Radhakrishnan
    A post-lysosomal cholesterol transport inhibitor reveals how the endoplasmic reticulum membrane regulates total cellular cholesterol by constantly monitoring a critical pool of cholesterol in the plasma membrane.

    Macrophages are necessary for epimorphic regeneration in African spiny mice

    Jennifer Simkin, Thomas R Gawriluk ... Ashley W Seifert
    Inflammatory cells differentially regulate a scarring versus a regenerating response to injury in mammals.

    PPP1R15A-mediated dephosphorylation of eIF2α is unaffected by Sephin1 or Guanabenz

    Ana Crespillo-Casado, Joseph E Chambers ... David Ron
    The notion that the drug-like small molecule Sephin1 protects against protein misfolding by selectively disrupting a cellular phosphatase is refuted.

    Polo-like kinase-dependent phosphorylation of the synaptonemal complex protein SYP-4 regulates double-strand break formation through a negative feedback loop.

    Saravanapriah Nadarajan, Talley J Lambert ... Monica P Colaiácovo
    PLK-1/2-mediated SYP-4 phosphorylation is dependent on crossover precursor formation, triggering a switch in the dynamic state of the synaptonemal complex that reduces the formation of further double-strand breaks at late meiotic prophase.

    The Sec14-like phosphatidylinositol transfer proteins Sec14l3/SEC14L2 act as GTPase proteins to mediate Wnt/Ca2+ signaling

    Bo Gong, Weimin Shen ... Shunji Jia
    Sec14l3/SEC14L2 respond to upstream Wnt/Frizzled/Dvl stimulation to recruit and activate phospholipase Cδ4a (Plcδ4a) to further initiate calcium release.

    Presynaptic morphology and vesicular composition determine vesicle dynamics in mouse central synapses

    Laurent Guillaud, Dimitar Dimitrov, Tomoyuki Takahashi
    In central synapses, the mobility and supply of synaptic vesicles are determined by two independent biological factors: the morphological and structural organization of nerve terminals and the molecular signature of vesicles.

    PDE2A2 regulates mitochondria morphology and apoptotic cell death via local modulation of cAMP/PKA signalling

    Stefania Monterisi, Miguel J Lobo ... Manuela Zaccolo
    The enzyme phosphodiesterase 2A2 localises at the mitochondrial membrane and its inhibition results in a local increase in cAMP concentration, mitochondrial elongation and resistance to apoptosis.
