    The Arabidopsis SAC9 enzyme is enriched in a cortical population of early endosomes and restricts PI(4,5)P2 at the plasma membrane

    Alexis Lebecq, Mehdi Doumane ... Marie-Cécile Caillaud
    SAC9 prevents the accumulation of PI(4,5)P2 in intracellular compartments, thereby contributing to clathrin-mediated endocytosis at the plasma membrane and regulating the cortical localization of its protein partner SH3P2.

    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.

    Sphingomyelin metabolism controls the shape and function of the Golgi cisternae

    Felix Campelo, Josse van Galen ... Vivek Malhotra
    Association of curvature generating proteins to the Golgi membranes by sphingomyelin metabolism essentially controls the flatness of a Golgi cisterna that is necessary for efficient sorting and export.

    Host-selected mutations converging on a global regulator drive an adaptive leap towards symbiosis in bacteria

    M Sabrina Pankey, Randi L Foxall ... Cheryl A Whistler
    Selective forces imposed by the squid animal host drive rapid adaptation of non-native Vibrio fischeri bacteria through convergent mutations of large effect, unmasking preexisting coordinated regulation of symbiosis.

    Axial contraction and short-range compaction of chromatin synergistically promote mitotic chromosome condensation

    Tom Kruitwagen, Annina Denoth-Lippuner ... Yves Barral
    Condensation and segregation of chromosomes during mitosis is caused by a combination of short-range interactions between nucleosomes and the long-range contraction of chromosome arms mediated by condensin.

    Cannabinoid signaling modulation through JZL184 restores key phenotypes of a mouse model for Williams–Beuren syndrome

    Alba Navarro-Romero, Lorena Galera-López ... Andres Ozaita
    A mouse model of Williams–Beuren syndrome allowed us to assess the endocannabinoid system and the impact of targeting the monoacyl glycerol lipase in modulating key phenotypes such as cognitive and hypersocial phenotype as well as the cardiac phenotype.

    Critical role for isoprenoids in apicoplast biogenesis by malaria parasites

    Megan Okada, Krithika Rajaram ... Paul A Sigala
    Malaria parasites target a polyprenyl synthase enzyme to the apicoplast organelle and require its activity to produce long-chain linear isoprenoids necessary for apicoplast biogenesis.

    Destabilizers of the thymidylate synthase homodimer accelerate its proteasomal degradation and inhibit cancer growth

    Luca Costantino, Stefania Ferrari ... Maria Paola Costi
    The dimer destabilizers cause a dimer-to-monomer equilibrium shift favoring the human thymidylate synthase monomer more degradable by the proteasome, thus breaking the long-standing link between inhibition and enhanced expression of the protein to fight cancer drug resistance.
