    Quantitative analysis of mammalian GIRK2 channel regulation by G proteins, the signaling lipid PIP2 and Na+ in a reconstituted system

    Weiwei Wang et al.
    The G protein subunits Gβγ and the signaling lipid PIP2 are simultaneously needed to activate the potassium ion channel GIRK2 to control the voltage across a lipid bilayer, while sodium ions modulate these molecules' effects.

    Functional genomics of lipid metabolism in the oleaginous yeast Rhodosporidium toruloides

    Samuel T Coradetti et al.
    Using barcoded mutagenesis and a high-throughput genetic screen results in the identification of 150 genes that affect lipid accumulation in a non-model yeast system.

    The autophagic membrane tether ATG2A transfers lipids between membranes

    Shintaro Maeda et al.
    The autophagy protein ATG2A tethers membranes and transfers lipids between them, suggesting that autophagosome membranes grow upon the acquisition of lipids from the ER through the ATG2A bridge.

    Lipid-mediated regulation of SKN-1/Nrf in response to germ cell absence

    Michael J Steinbaugh et al.
    Germ cell ablation delays C. elegans aging, in part, because unconsumed fat triggers activation of the detoxification factor SKN-1/Nrf, which is regulated by lipid signals and maintains lipid homeostasis.

    A novel role for lipid droplets in the organismal antibacterial response

    Preetha Anand et al.
    Histones bound to lipid droplets inside cells offer protection against bacteria in flies, and possibly mice, thus suggesting a possible new innate immunity pathway.

    Identification of an allosteric binding site on the human glycine transporter, GlyT2, for bioactive lipid analgesics

    Shannon N Mostyn et al.
    Identification of how bioactive lipids bind and inhibit glycine transporters has the potential to be exploited in the development of a new class of analgesics for chronic pain.

    Lipid transfer from plants to arbuscular mycorrhiza fungi

    Andreas Keymer et al.
    Identification of two arbuscular mycorrhiza-specific lipid biosynthesis mutants and fatty acid transfer experiments reveal that host plant lipids are transferred to symbiotic fungi and needed for their development.

    The dimerization equilibrium of a ClC Cl/H+ antiporter in lipid bilayers

    Rahul Chadda et al.
    Measuring the equilibrium dimerization of a polytopic membrane protein in lipid bilayers forms the basis of a new system for studying the physical forces that stabilize membrane protein association in membranes.

    Arf1/COPI machinery acts directly on lipid droplets and enables their connection to the ER for protein targeting

    Florian Wilfling et al.
    The targeting of proteins from the endoplasmic reticulum to lipid droplets relies on surface modulation of the lipid droplet by the Arf1/COPI machinery.

    Cryo-EM structures and functional characterization of the murine lipid scramblase TMEM16F

    Carolina Alvadia et al.
    While activated by a common mechanism, both functions in TMEM16F - lipid scrambling and ion conduction - are likely mediated by alternate protein conformations that are at equilibrium in the ligand-bound state.
