    The magnesium transporter A is activated by cardiolipin and is highly sensitive to free magnesium in vitro

    Saranya Subramani et al.
    A magnesium transporter from Escherichia coli depends strongly on the lipid cardiolipin and acts both as a sensor and a transporter of magnesium.

    Epithelial magnesium transport by TRPM6 is essential for prenatal development and adult survival

    Vladimir Chubanov et al.
    Mice deficient in the TRPM6 channel suffer from impaired prenatal development, shortened lifespan, growth deficit and disturbed energy balance due to a defect in epithelial Mg2+ uptake, thus highlighting a pivotal role of TRPM6 in organismal Mg2+ homeostasis.

    sRNA-mediated activation of gene expression by inhibition of 5'-3’ exonucleolytic mRNA degradation

    Sylvain Durand et al.
    Small regulatory RNAs are able to modulate mRNA degradation rates by controlling access to the 5' end of mRNAs in bacteria.

    9Å structure of the COPI coat reveals that the Arf1 GTPase occupies two contrasting molecular environments

    Svetlana O Dodonova et al.
    A molecular model of the assembled COPI coat, determined by cryo-electron tomography of an in vitro reconstituted budding reaction, reveals details of interactions mediating coat assembly and shows the binding site of ArfGAP2.

    A chloroplast retrograde signal, 3’-phosphoadenosine 5’-phosphate, acts as a secondary messenger in abscisic acid signaling in stomatal closure and germination

    Wannarat Pornsiriwong et al.
    Molecular signals from chloroplasts can synergistically interact with the plant hormone, abscisic acid (ABA), to regulate non-canonical signaling pathways mediating fundamental cellular processes including stomatal closure, seed dormancy and germination.

    Kinetics of the LOV domain of ZEITLUPE determine its circadian function in Arabidopsis

    Ashutosh Pudasaini et al.
    In the plant circadian clock photoreceptor ZEITLUPE, evolutionarily selected residues distinguish photocycle kinetics and allosteric signal transduction pathways to permit proper circadian timing.

    Fluorescent sensors reporting the activity of ammonium transceptors in live cells

    Roberto De Michele et al.
    A modified form of Green Fluorescent Protein integrated into an ammonium transporter provides a sensor that can be used to monitor transport activity in vivo.

    Stimulus-dependent recruitment of lateral inhibition underlies retinal direction selectivity

    Qiang Chen et al.
    Synapse-specific genetic manipulations show that distinct GABAergic inputs are differentially recruited to encode motion direction in the retina in a stimulus-dependent manner.

    Non-canonical Wnt signalling modulates the endothelial shear stress flow sensor in vascular remodelling

    Claudio A Franco et al.
    A threshold level of blood flow initiates developmental blood vessel regression; this threshold can be regulated by non-canonical Wnt ligands.

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

    Liang Ge et al.
    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.
