    Regulation of cell protrusions by small GTPases during fusion of the neural folds

    Ana Rolo et al.
    The completion of neural tube closure requires small GTPase-regulated membrane protrusions from non-neural ectoderm cells at the tips of the neural folds.

    Glutaminase 2 is a novel negative regulator of small GTPase Rac1 and mediates p53 function in suppressing metastasis

    Cen Zhang et al.
    The GLS2 enzyme suppresses cancer metastasis by interacting with the small GTPase Rac1 and inhibiting its activity.

    A putative structural mechanism underlying the antithetic effect of homologous RND1 and RhoD GTPases in mammalian plexin regulation

    Yanyan Liu et al.
    Small Rho GTPases confer up- and downregulation in mammalian plexin signaling by differential interactions with cell membrane.

    Rap2 and TNIK control Plexin-dependent tiled synaptic innervation in C. elegans

    Xi Chen et al.
    Plexin controls the spatial distribution of synapses by locally inhibiting Rap2 small GTPase activity along the axon, and a Rap2 effector, TNIK, which also plays a key role in inhibiting synapse number.

    Structures of TorsinA and its disease-mutant complexed with an activator reveal the molecular basis for primary dystonia

    F Esra Demircioglu et al.
    High resolution structures of the essential human AAA+ ATPase TorsinA and its disease mutant in complex with an activator reveal details of the interaction that will guide drug design and further functional characterization.

    The GTPase IFT27 is involved in both anterograde and retrograde intraflagellar transport

    Diego Huet et al.
    A small GTPase within the flagellum can participate in the control of transport from the base to the tip of the flagellum, and back again.

    Loss of Cdc42 leads to defects in synaptic plasticity and remote memory recall

    Il Hwan Kim et al.
    Conditional knockout of the small GTPase Cdc42 in excitatory neurons of the mouse forebrain leads to impaired long-term synaptic plasticity and impaired retrieval of remote memory.

    Re-expression of SMARCA4/BRG1 in small cell carcinoma of ovary, hypercalcemic type (SCCOHT) promotes an epithelial-like gene signature through an AP-1-dependent mechanism

    Krystal Ann Orlando et al.
    BRG1 loss drives initiation and progression in human cancers through changes in specific differentiation programs in an AP-1-dependent manner.

    ARL3 activation requires the co-GEF BART and effector-mediated turnover

    Yasmin ElMaghloob et al.
    BART is a co-GEF for ARL3 and maintains the active ARL3-GTP until it is recycled by ARL3 effectors.

    Sequence co-evolution gives 3D contacts and structures of protein complexes

    Thomas A Hopf et al.
    Interactions in protein complexes can be predicted from evolutionary information from genomic sequences.
