    Structural basis for isoform-specific kinesin-1 recognition of Y-acidic cargo adaptors

    Stefano Pernigo, Magda S Chegkazi ... Roberto A Steiner
    X-ray crystallography reveals how kinesin-1 recognises a novel class of cargo adaptor motifs in an isoform-specific manner.

    Doublecortin and JIP3 are neural-specific counteracting regulators of dynein-mediated retrograde trafficking

    Xiaoqin Fu, Lu Rao ... Judy Shih-Hwa Liu
    DCX negatively regulates dynein-mediated retrograde transport through two critical interactions by regulating dynein binding to microtubules and regulating the composition of dynein/dyactin/JIP3 motor complex.

    Retrograde Ret signaling controls sensory pioneer axon outgrowth

    Adam Tuttle, Catherine M Drerup ... Alex V Nechiporuk
    Long-range Ret receptor signaling promotes axon outgrowth and regulates growth cone dynamics in pioneer neurons by inducing transcriptional changes in Myosin-X expression.

    Rab10 regulates the sorting of internalised TrkB for retrograde axonal transport

    Oscar Marcelo Lazo, Giampietro Schiavo
    BDNF-regulated deployment of Rab10 to the distal axon regulates retrograde propagation of neurotrophic signalling, providing a flexible mechanism to fine-tune the communication between the synapse and the cell body of neurons, as well as novel therapeutic targets for neurodegeneration.

    The E3 ubiquitin ligase IDOL regulates synaptic ApoER2 levels and is important for plasticity and learning

    Jie Gao, Mate Marosi ... Peter Tontonoz
    Control of lipoprotein receptor protein levels at synapses by the E3 ubiquitin ligase IDOL is shown to be important for the plasticity of neuronal dendrites in vitro and learning and memory in mice.

    Casein kinase 1G2 suppresses necroptosis-promoted testis aging by inhibiting receptor-interacting kinase 3

    Dianrong Li, Youwei Ai ... Xiaodong Wang
    Casein kinase 1G2 interacts with and inhibits the activation of receptor-interacting kinase 3, RIP3, in response to TNF and toll-like receptor family members and attenuates its necroptosis signaling activity.
