    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.

    Pre-existing bilayer stresses modulate triglyceride accumulation in the ER versus lipid droplets

    Valeria Zoni et al.
    In parallel to protein-driven processes, characteristic physicochemical properties of the endoplasmic reticulum membrane modulate intracellular fat accumulation and lipid droplet formation.

    Membranes linked by trans-SNARE complexes require lipids prone to non-bilayer structure for progression to fusion

    Michael Zick et al.
    Lipids with a propensity to form nonbilayer structures must be present for the last step of membrane fusion to take place.

    Large domain movements through the lipid bilayer mediate substrate release and inhibition of glutamate transporters

    Xiaoyu Wang, Olga Boudker
    Substrate releasing or inhibitor binding on the intracellular side of a glutamate transporter homologue require movements of the transport domain through the lipid membrane, which undergoes adaptive deformations.

    Bovine F1Fo ATP synthase monomers bend the lipid bilayer in 2D membrane crystals

    Chimari Jiko et al.
    The transmembrane shape of the F1Fo ATP synthase monomer provides the molecular basis of high curvature at the ridges of mammalian mitochondrial cristae.

    Pre-transition effects mediate forces of assembly between transmembrane proteins

    Shachi Katira et al.
    A general mechanism for how powerful forces of assembly and protein mobility can emerge from phase transitions is established.

    Cryo-EM structures and functional properties of CALHM channels of the human placenta

    Katarzyna Drożdżyk et al.
    Members of the calcium homeostasis modulator family expressed in the placenta form large channels with unknown activation properties that harbor a lipid bilayer on the inside of a cylindrical pore.

    Lipid polarity gradient formed by ω-hydroxy lipids in tear film prevents dry eye disease

    Masatoshi Miyamoto et al.
    (O-Acyl)-ω-hydroxy fatty acids and their derivatives, produced by the fatty acid ω-hydroxylase Cyp4f39, form a lipid polarity gradient in the lipid layer of the tear film and prevent dry eye.

    Molecular basis of force-from-lipids gating in the mechanosensitive channel MscS

    Bharat Reddy et al.
    The structure of the mechanosensitive channel MscS embedded in a lipid bilayer redefines the nature, location and importance of lipid–protein interactions in the gating of mechanosensitive channels.

    Exceptional stability of a perilipin on lipid droplets depends on its polar residues, suggesting multimeric assembly

    Manuel Giménez-Andrés et al.
    The amphipathic helix of perilipin 4 relies on the organization of its polar residues to form a remarkably immobile and stable protein layer on the surface of lipid droplets.
