Cryo-electron microscopy reconstructions of two microtubule-bound transport kinesins at 7 Å resolution reveal how microtubule track binding stimulates ADP release, primes the active site for ATP binding and enables force generation.

Microtubule nucleation from the nuclear envelope in fission yeast involves repurposing of nuclear export proteins for a non-export-related function, docking cytoplasmic proteins at nuclear pore complexes.

Using linked TOG domains that each bind a curved conformation of αβ-tubulin, a microtubule polymerase catalyzes fast elongation by concentrating αβ-tubulin near the polymer end.

A buried mutation in αβ-tubulin reveals an allosteric response to GDP in the lattice that dictates microtubule catastrophe and shrinking.

The structural and functional analysis demonstrates the mechanism of dual functional, motility and microtubule depolymerization in a unique motor, KIF19A.

Centriole integrity is ensured by the connection between the inner scaffold and microtubule triplets through POC16/WDR90 proteins.

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.

Autocatalytic growth of a microtubule polymer network allows extremely large egg cells to self-organize and divide rapidly.

Microtubule networks in frog egg extracts can spontaneously contract in a manner that can be quantitatively described by an active fluid model.

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.
