    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.

    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.

    Design of biochemical pattern forming systems from minimal motifs

    Philipp Glock et al.
    Theoretical analysis and in vitro reconstitution of a biological reaction-diffusion system identify key functional motifs as well as underlying principles and enable rebuilding pattern formation in a modular fashion.

    In vitro reconstitution of branching microtubule nucleation

    Ammarah Tariq et al.
    Purification of two conserved protein complexes, the γ-TuRC and Augmin, using a simple affinity technique, demonstrates that they are necessary and sufficient for the essential phenomenon of branching microtubule nucleation.

    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.

    Design principles of a microtubule polymerase

    Elisabeth A Geyer et al.
    Antagonism between binding to unpolymerized subunits and to the lattice leads to a ratcheting model for the processive action of a microtubule polymerase.

    Mapping out Min protein patterns in fully confined fluidic chambers

    Yaron Caspi, Cees Dekker
    The geometry selection rules of dynamic Min protein patterns are determined in fully confined fluidic chambers, showing that both oscillations and running waves are derivatives of spiral rotations that are established as the majority pattern.

    Symmetry breaking in reconstituted actin cortices

    Enas Abu Shah, Kinneret Keren
    A reconstituted system has been developed that self-organizes into dynamic actin cortices capable of spontaneous polarization, similar to the initial cortical polarization observed in cells during embryogenesis and development.

    RNA-directed activation of cytoplasmic dynein-1 in reconstituted transport RNPs

    Mark A McClintock et al.
    Reconstitution of dynein-based mRNA transport with purified components reveals a pivotal role of an RNA localisation signal in controlling the assembly and activity of the translocation machinery.

    Structural insight into TPX2-stimulated microtubule assembly

    Rui Zhang et al.
    A combination of cryo-electron microscopy of TPX2 bound to microtubules and in vitro reconstitution experiments reveals a novel microtubule interaction mode that explains how TPX2 promotes microtubule nucleation and stabilization.
