    Mapping the functional versatility and fragility of Ras GTPase signaling circuits through in vitro network reconstitution

    Scott M Coyle, Wendell A Lim
    A systems level reconstitution of H-Ras GTPase signaling reveals a rich space of tunable dynamic outputs and clarifies the consequences of oncogenic perturbations to signaling.

    Reconstitution of self-organizing protein gradients as spatial cues in cell-free systems

    Katja Zieske, Petra Schwille
    A minimal cell-like system with defined geometry has been used to investigate the establishment and spatial control of a protein gradient that positions the bacterial cell division machinery.

    Biochemical reconstitution of branching microtubule nucleation

    Raymundo Alfaro-Aco et al.
    The protein TPX2 and the protein complex augmin together recruit the microtubule nucleator γ-TuRC to a pre-existing microtubule where they initiate branching microtubule nucleation.

    Reconstitution of selective HIV-1 RNA packaging in vitro by membrane-bound Gag assemblies

    Lars-Anders Carlson et al.
    In vitro reconstitution shows how HIV-1 Gag assemblies on membranes can package the RNA genome in the presence of a vast excess of competing cellular RNAs, and that selectivity and immature lattice assembly are deeply intertwined with one another.

    Identification and reconstitution of the rubber biosynthetic machinery on rubber particles from Hevea brasiliensis

    Satoshi Yamashita et al.
    The first de novo synthesis of polyisoprenoids correspond to natural rubber in vitro with the recombinant proteins is achieved by identification and cell-free translation-coupled reconstitution of the rubber biosynthetic machinery on rubber particles.

    Reconstitution of dynein transport to the microtubule plus end by kinesin

    Anthony J Roberts et al.
    In vitro reconstitution reveals how a system of molecules works together to transport the motor protein dynein to the start of its track.

    Two forms of Opa1 cooperate to complete fusion of the mitochondrial inner-membrane

    Yifan Ge et al.
    An in vitro reconstitution assay reveals stoichiometric levels of the short form of Opa1 work together with the long form of Opa1 to mediate efficient and fast membrane pore opening.

    The P2X7 receptor forms a dye-permeable pore independent of its intracellular domain but dependent on membrane lipid composition

    Akira Karasawa et al.
    Functional reconstitution of a mammalian P2X7 receptor uncovers an intrinsic and lipid-dependent dye-permeable membrane pore.

    Membrane bridging by Munc13-1 is crucial for neurotransmitter release

    Bradley Quade et al.
    Cryo-electron tomography, reconstitution, and electrophysiological data show that a fundamental function of Munc13-1 is to bridge synaptic vesicles to the presynaptic plasma membrane.
