Kinesins are a large superfamily of cytoskeletal motor protein that hydrolyse ATP to move along microtubules and perform diverse functions in intracellular trafficking and cell division.

    Assembly of the mitotic spindle requires timely separation of the centrosomes. Their movement apart is driven by the plus-end-directed kinesin Eg5. A new study demonstrates that the kinesin KIFC3 provides an opposing microtubule-based cohesive force that modulates centrosome separation and ensures accurate chromosome segregation.

    The combination of topological constraints and deformability in an active system of microtubules and molecular motors leads to rich dynamic behaviour.

    Mitosis depends upon the action of the mitotic spindle, a subcellular machine that uses microtubules (MTs) and motors to assemble itself and to coordinate chromosome segregation. Recent work illuminates how the motor-driven poleward sliding of MTs — nucleated at centrosomes, chromosomes and on pre-existing MTs — contributes to spindle assembly and length control.

    The kinesin-4 motor protein Kif7 regulates Hedgehog signalling at cilia in mammals by controlling the activity of Gli transcription factors. Kif7 is now found to inhibit microtubule growth to restrict and coordinate the length of axonemal microtubules at the ciliary tip. Such Kif7-mediated organization of the ciliary tip compartment regulates Gli activity and is proposed to be required for correct Hedgehog signalling.
