    The Rab6-regulated KIF1C kinesin motor domain contributes to Golgi organization

    Peter L Lee, Maikke B Ohlson, Suzanne R Pfeffer
    Rab6A binds directly to both the C-terminus and the N-terminal motor domain of the kinesin KIF1C to regulate vesicle motility and Golgi organization.

    BLOS1 mediates kinesin switch during endosomal recycling of LDL receptor

    Chang Zhang, Chanjuan Hao ... Wei Li
    BLOS1 is a new regulator of LDLR endosomal recycling through coordinating kinesins during long-range transport, and depletion of BLOS1 in mouse liver leads to aberrant lipid metabolism.

    Kinesin-4 KIF21B is a potent microtubule pausing factor

    Wilhelmina E van Riel, Ankit Rai ... Anna Akhmanova
    Kinesin-4 KIF21B combines a processive motor activity with two non-motor microtubule-binding domains and an autoregulatory region to induce pausing of microtubule plus ends.

    Specific depletion of the motor protein KIF5B leads to deficits in dendritic transport, synaptic plasticity and memory

    Junjun Zhao, Albert Hiu Ka Fok ... Kwok-On Lai
    Two homologous kinesin motors, KIF5A and KIF5B, have distinct functions in dendritic spine morphogenesis, and KIF5B plays a role in synaptic plasticity and memory.

    Kinesin-4 KIF21B limits microtubule growth to allow rapid centrosome polarization in T cells

    Peter Jan Hooikaas, Hugo GJ Damstra ... Anna Akhmanova
    Kinesin-4 KIF21B promotes rapid reorientation of the microtubule network during formation of immunological synapse in T cells by acting as a pausing and catastrophe-inducing factor that keeps microtubules short.

    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.
