    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.

    A bacterial membrane sculpting protein with BAR domain-like activity

    Daniel A Phillips, Lori A Zacharoff ... Sarah M Glaven
    Uniform diameter and curvature of the outer membrane extensions and vesicles of Shewanella oneidensis are maintained by a bacterial Bin/Amphiphysin/Rvs (BAR) domain-like protein BdpA.

    Exercise-induced enhancement of synaptic function triggered by the inverse BAR protein, Mtss1L

    Christina Chatzi, Yingyu Zhang ... Gary L Westbrook
    Single episodes of voluntary exercise induced a functional increase in hippocampal synapses mediated by activity-dependent expression of the BAR protein Mtss1L, acting as a novel early effector of synapse formation.

    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.

    A mechanosensing mechanism controls plasma membrane shape homeostasis at the nanoscale

    Xarxa Quiroga, Nikhil Walani ... Pere Roca-Cusachs
    Cell stretch release generates plasma membrane (PM) evaginations of ≈100 nm, triggering a local event of actin polymerization that flattens and recovers PM shape.

    Full assembly of HIV-1 particles requires assistance of the membrane curvature factor IRSp53

    Kaushik Inamdar, Feng-Ching Tsai ... Delphine Muriaux
    The formation of HIV-1 particles requires a bending of the membrane that cannot be achieved by the Gag protein alone and thus there is need for the I-BAR protein IRSp53 to aid in the formation of HIV-1 buds.

    Structural inhibition of dynamin-mediated membrane fission by endophilin

    Annika Hohendahl, Nathaniel Talledge ... Aurélien Roux
    The BAR protein endophilin spaces out turns of the dynamin helix, blocking its active conformational change and membrane fission.

    Visualizing the functional architecture of the endocytic machinery

    Andrea Picco, Markus Mund ... Marko Kaksonen
    A combination of light and electron microscopy data provide new insights into the dynamic architecture and the function of the endocytic protein machinery in relation to membrane shape changes in vivo.

    Selecting the most appropriate time points to profile in high-throughput studies

    Michael Kleyman, Emre Sefer ... Ziv Bar-Joseph
    The Time Point Selection (or TPS) method is a general protocol for determining sampling rates for high throughout time series biological studies, that is efficient, cheap, scalable and works well for several different types of molecular data.
