The somatic Golgi acts as an asymmetric MTOC within Drosophila neurons, and this, together with the action Kinesin-2, helps maintain minus-end-out microtubule polarity with proximal dendrites.
The tubulin GTPase cycle structurally modulates the microtubule cap, causing lattice expansion, which is an intermediate state involved in phosphate release and regulatory signaling.
Biochemical, single molecule, cell and structural biology studies reveal an interaction between the kinesin-5 tail and motor domains regulating high-force production, which is critical for microtubule sliding motility.
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.
Human chromosome-microtubule attachments are stabilised by Astrin-mediated dynamic delivery of PP1 phosphatase to the attachment site, which ensures the normal segregation of chromosomes.
Biochemical and cell biological analyses reveal that the Astrin-SKAP complex acts to stabilize kinetochore-microtubule interactions through its intrinsic microtubule binding activity and its association with the Ndc80 complex, the core component of the kinetochore-microtubule interface.
Quantitative microscopy and theory show that the size of Xenopus laevis egg extract spindles is controlled by a spatially-regulated autocatalytic growth mechanism driven by microtubule-stimulated microtubule nucleation.
