    Dynamic clustering of dynamin-amphiphysin helices regulates membrane constriction and fission coupled with GTP hydrolysis

    Tetsuya Takeda et al.
    A new approach using combination of electron microscopy (EM) and high-speed atomic force microscopy (HS-AFM) clearly demonstrates dynamics of dynamin-amphiphysin complexes during membrane constriction and fission suggesting a novel 'clusterase' model of the dynamin-mediated membrane fission.

    The role of scaffold reshaping and disassembly in dynamin driven membrane fission

    Martina Pannuzzo et al.
    Computational modeling of a dynamin-constricted membrane neck can rank proposed shape changes of the helical scaffold in terms of their fission aptitude and elucidate the associated pathways.

    Structural inhibition of dynamin-mediated membrane fission by endophilin

    Annika Hohendahl et al.
    The BAR protein endophilin spaces out turns of the dynamin helix, blocking its active conformational change and membrane fission.

    Dynamic recruitment of the curvature-sensitive protein ArhGAP44 to nanoscale membrane deformations limits exploratory filopodia initiation in neurons

    Milos Galic et al.
    Local inward plasma membrane deformations caused by actomyosin-dependent contraction trigger the dynamic recruitment of a curvature-sensitive actin-regulatory protein, which represents a receptor-independent auto-regulatory mechanism to control local actin polymerization dynamics at the plasma membrane.

    Binding mechanism of the matrix domain of HIV-1 gag on lipid membranes

    Viviana Monje-Galvan, Gregory A Voth
    Unbiased molecular dynamics simulations reveal the insertion mechanism of the lipidated tail of the matrix domain of HIV-1 Gag into realistic membrane models and show its effect on lipid sorting.

    Recruitment dynamics of ESCRT-III and Vps4 to endosomes and implications for reverse membrane budding

    Manuel Alonso Y Adell et al.
    Quantitative 3D lattice light sheet microscopy of unperturbed cells combined with electron tomography and acute loss of function experiments reveals how dynamic ESCRT-III/Vps4 assemblies succeed in reverse membrane budding on endosomes.

    State-dependent cell-type-specific membrane potential dynamics and unitary synaptic inputs in awake mice

    Aurélie Pala, Carl CH Petersen
    Membrane potential recordings in awake mice from two genetically defined classes of neocortical inhibitory neurons reveal their distinct patterns of activity and unitary excitatory synaptic inputs, which are differentially modulated by behavior and local network activity.
