    Deletion of a kinesin I motor unmasks a mechanism of homeostatic branching control by neurotrophin-3

    Thomas O Auer et al.
    Disrupting synapse formation between the retina and the brain in zebrafish larvae-by eliminating the molecular motor Kif5A-triggers a compensatory increase in the branching of retinal axons aimed at restoring synapse number.

    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.

    High mTOR activity is a hallmark of reactive natural killer cells and amplifies early signaling through activating receptors

    Antoine Marçais et al.
    Chronic engagement of Natural killer cell inhibitory receptors by MHC-I molecules maintains a high activity of the mTOR pathway allowing subsequent amplification of signaling through activating receptors upon acute stimulation.

    The C-terminal region of the motor protein MCAK controls its structure and activity through a conformational switch

    Sandeep K Talapatra et al.
    Structural analysis of the kinesin-13 MCAK bound to its C-terminal tail reveals the molecular basis for the conformation of kinesin-13 in solution and the mechanism that triggers long-range conformational changes upon microtubule binding.

    Frizzled3 controls axonal development in distinct populations of cranial and spinal motor neurons

    Zhong L Hua et al.
    The signaling molecule Frizzled3 plays a part in the development of the nervous system by controlling the ability of motor neurons to form connections with distant target muscles.

    Molecular basis for dyneinopathies reveals insight into dynein regulation and dysfunction

    Matthew G Marzo et al.
    A mutagenesis screen in budding yeast sheds light on dynein regulation and function, and reveals the molecular basis for disease in patients suffering from neuropathies caused by dynein dysfunction.

    Length regulation of multiple flagella that self-assemble from a shared pool of components

    Thomas G Fai et al.
    In the microbe Chlamydomonas reinhardtii, a disassembly rate which depends on flagellar length provides an effective method to regulate the length of its two flagella.

    A terminal selector prevents a Hox transcriptional switch to safeguard motor neuron identity throughout life

    Weidong Feng et al.
    A molecular mechanism that involves highly conserved transcription factors enables cholinergic motor neurons of the nematode Caenorhabditis elegans to become and remain functional.

    Mechanochemical coupling and bi-phasic force-velocity dependence in the ultra-fast ring ATPase SpoIIIE

    Ninning Liu et al.
    Probing the DNA motor SpoIIIE at the single-molecule level has revealed its force-generating step, rich translocation dynamics during motor operation and a novel, bi-phasic mechanical response to opposing force.
