    No turnover in lens lipids for the entire human lifespan

    Jessica R Hughes et al.
    The carbon in lens membrane lipids correlates to the year of birth of an individual, a phenomenon that is unprecedented in the current body of literature.

    Defining key roles for auxiliary proteins in an ABC transporter that maintains bacterial outer membrane lipid asymmetry

    Shuhua Thong et al.
    Auxiliary proteins play functional roles in modulating the assembly and activity of a non-canonical ABC transporter that is important for the maintenance of outer membrane lipid asymmetry.

    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.

    Membrane transporter dimerization driven by differential lipid solvation energetics of dissociated and associated states

    Rahul Chadda et al.
    Differences in the lipid solvation energetics of associated and dissociated states is a primary driving force for membrane protein oligomerization, presenting a molecular mechanism for lipid regulation in biology.

    Single-particle cryo-EM structure of a voltage-activated potassium channel in lipid nanodiscs

    Doreen Matthies et al.
    The structure of a voltage-activated potassium channel in lipid nanodiscs solved using cryo-electron microscopy is similar to previous X-ray structures, and provides insights into the mechanism of C-type inactivation.

    Obesity-linked suppression of membrane-bound O-acyltransferase 7 (MBOAT7) drives non-alcoholic fatty liver disease

    Robert N Helsley et al.
    Loss of function of membrane-bound O-acyltransferase 7 (MBOAT7), but not transmembrane channel-like 4 (TMC4), promotes hepatic steatosis.

    Remodeling of whole-body lipid metabolism and a diabetic-like phenotype caused by loss of CDK1 and hepatocyte division

    Jin Rong Ow et al.
    Loss of hepatic Cdk1 leads to oxidative stress, increased fatty acids in blood, and hyperinsulinemia, which resulted in insulin resistance and hepatic steatosis, similar as in diabetes.

    Structural basis of Ca2+-dependent activation and lipid transport by a TMEM16 scramblase

    Maria E Falzone et al.
    Structures of a TMEM16 phospholipid scramblase reveal that its Ca2+-dependent activation entails global conformational changes and how these rearrangements affect the membrane to enable transbilayer lipid transfer.

    Human DECR1 is an androgen-repressed survival factor that regulates PUFA oxidation to protect prostate tumor cells from ferroptosis

    Zeyad D Nassar et al.
    DECR1, a rate-limiting enzyme for polyunsaturated fatty acid (PUFA) β-oxidation, is an androgen-repressed gene in prostate cancer cells that limits oxidative stress to promote cancer cell survival.
