    Multiple polarity kinases inhibit phase separation of F-BAR protein Cdc15 and antagonize cytokinetic ring assembly in fission yeast

    Rahul Bhattacharjee, Aaron R Hall ... Kathleen L Gould
    Biochemical studies and molecular dynamics simulations indicate that dephosphroylation of F-BAR protein Cdc15 promotes cytokinesis ring assembly in yeast via conformation change of intrinsically disorder regions and condensate formation.

    Functional interdependence of the actin nucleator Cobl and Cobl-like in dendritic arbor development

    Maryam Izadi, Eric Seemann ... Michael M Kessels
    Extended biochemical and functional analyses in primary neurons show that early neuronal morphogenesis critically relies on cooperation of the actin nucleator Cobl and its ancestor Cobl-like and uncover their cooperative mechanisms at dendritic branch initiation sites.

    Structural organization and dynamics of FCHo2 docking on membranes

    Fatima El Alaoui, Ignacio Casuso ... Laura Picas
    The pioneering endocytic protein FCHo2 promotes clathrin-coated structures assembly via the formation of phosphoinositide-enriched domains at the boundary of cargo receptors.

    The membrane-associated proteins FCHo and SGIP are allosteric activators of the AP2 clathrin adaptor complex

    Gunther Hollopeter, Jeffrey J Lange ... Erik M Jorgensen
    Endocytosis is triggered by membrane-associated proteins that transform the clathrin adaptor into an active complex.

    ASPEN, a methodology for reconstructing protein evolution with improved accuracy using ensemble models

    Roman Sloutsky, Kristen M Naegle
    Using different sets of input sequences to evolutionary reconstruction algorithms results in the exploration of many possible models, the intergration over which produces significantly more accurate models.

    Ezrin enrichment on curved membranes requires a specific conformation or interaction with a curvature-sensitive partner

    Feng-Ching Tsai, Aurelie Bertin ... Patricia Bassereau
    Ezrin, an important actin-membrane linker, can zip adjacent membranes, be enriched to positively-curved membranes when phosphorylated and to negatively-curved membranes through a direct interaction with membrane curvature sensor I-BAR domain proteins.

    Lipid homeostasis is essential for a maximal ER stress response

    Gilberto Garcia, Hanlin Zhang ... Andrew Dillin
    A genetic screen identifies a lipid pathway which impacts the endoplasmic reticulum unfolded protein response and highlights a mechanism through which lipid disequilibrium might facilitate the progression of proteopathic diseases.

    Deciphering caveolar functions by syndapin III KO-mediated impairment of caveolar invagination

    Eric Seemann, Minxuan Sun ... Britta Qualmann
    Mice lacking the membrane-shaping protein syndapin III show severe reduction of caveolae reminiscent of human caveolinopathies but maintain plasma membrane-associated caveolar coats proteins and thereby unveil physiological impairments associated with lack of invaginated caveolae.

    Allosteric ligands control the activation of a class C GPCR heterodimer by acting at the transmembrane interface

    Lei Liu, Zhiran Fan ... Jianfeng Liu
    Functional analysis reveals a distinct mode of action of the allosteric modulators in the GABAB receptor in a pocket that is formed only in the active state and identifies a region in the GABAB2 subunit important for allosteric agonism.
