    Structure of dual BON-domain protein DolP identifies phospholipid binding as a new mechanism for protein localisation

    Jack Alfred Bryant, Faye C Morris ... Ian R Henderson
    Analysis of the E. coli protein DolP reveals the first dual BON-domain structure and identifies phospholipid binding as a new mechanism for protein localisation to the outer membrane division site.

    Acyl chain asymmetry and polyunsaturation of brain phospholipids facilitate membrane vesiculation without leakage

    Marco M Manni, Marion L Tiberti ... Bruno Antonny
    The asymmetric combination of saturated and polyunsaturated acyl chains in phospholipids as typically observed in synapses makes membranes prone to deformation and fission without compromising their impermeability.

    Fatty acid remodeling by LPCAT3 enriches arachidonate in phospholipid membranes and regulates triglyceride transport

    Tomomi Hashidate-Yoshida, Takeshi Harayama ... Takao Shimizu
    LPCAT3 incorporates arachidonic acid into membrane phospholipids, which promotes lipoprotein assembly by enabling triacylgylcerols to cluster in the membrane.

    Identification of a lipid scrambling domain in ANO6/TMEM16F

    Kuai Yu, Jarred M Whitlock ... H Criss Hartzell
    The amino acids that are necessary for phospholipid scrambling by ANO6/TMEM16F can, via domain swapping, confer scrambling activity to the chloride ion channel ANO1 that normally does not scramble phospholipids.

    Structure of bacterial phospholipid transporter MlaFEDB with substrate bound

    Nicolas Coudray, Georgia L Isom ... Damian C Ekiert
    Structure of MlaFEDB ABC transporter with substrate bound in the outward-open pocket of MlaE provides mechanistic insights into lipid transport within the Gram-negative bacterial cell envelope.

    An ER phospholipid hydrolase drives ER-associated mitochondrial constriction for fission and fusion

    Tricia T Nguyen, Gia K Voeltz
    ABHD16A is a phospholipid-modifying endoplasmic reticulum (ER) membrane protein required for both mitochondrial fission and fusion machinery recruitment to ER-associated mitochondrial constrictions.

    Fat body phospholipid state dictates hunger-driven feeding behavior

    Kevin P Kelly, Mroj Alassaf ... Akhila Rajan
    Behavioral, lipidomic, and genetic analyses of adult Drosophila on a chronic high-sugar regime identified that fat body activity of a phospholipid biosynthesis enzyme, Pect, regulates insulin sensitivity and hunger response.

    A highly conserved host lipase deacylates oxidized phospholipids and ameliorates acute lung injury in mice

    Benkun Zou, Michael Goodwin ... Mingfang Lu
    Acyloxyacyl hydrolase, the host lipase that detoxifies bacterial lipopolysaccharides, also deacylates oxidized phospholipids, preventing inflammasome activation in macrophages in vitro and ameliorating acute lung injury in vivo.

    Structural, mechanistic, and physiological insights into phospholipase A-mediated membrane phospholipid degradation in Pseudomonas aeruginosa

    Florian Bleffert, Joachim Granzin ... Filip Kovacic
    Membrane homeostasis in bacteria relies on the controlled degradation of endogenous phospholipids by intracellular phospholipases A, however their structures and catalytic mechanism are still poorly understood.

    Differential TAM receptor–ligand–phospholipid interactions delimit differential TAM bioactivities

    Erin D Lew, Jennifer Oh ... Greg Lemke
    Signaling by TAM receptor tyrosine kinases requires the coincident engagement of a TAM ligand with both its receptor and the phospholipid phosphatidylserine.
