Study demonstrated that diffusible microtubule crosslinker Ase1 generated directed microtubule sliding when confined between partially overlapping microtubules. The Ase1-generated forces, directly measured by optical tweezers to be in the piconewton-range, were sufficient to antagonize motor-protein driven microtubule sliding.
Title: Diffusible crosslinkers generate directed forces in microtubule networks.

Show that Ase1, a member of the conserved MAP65/PRC1 family of microtubule-bundling proteins, enables the formation of stable antiparallel overlaps through adaptive braking of Kinesin-14-driven microtubule-microtubule sliding.
Title: Adaptive braking by Ase1 prevents overlapping microtubules from sliding completely apart.

An Ase1/Prc1-dependent mechanism that prevents spindle collapse and thus asymmetric division is required for correction of merotelic attachment in anaphase.
Title: Ase1/Prc1-dependent spindle elongation corrects merotely during anaphase in fission yeast.

Data show that fission yeast kinesin-6 motor klp9p binds to the microtubule antiparallel bundler ase1p at the midzone at anaphase B onset.
Title: Phospho-regulated interaction between kinesin-6 Klp9p and microtubule bundler Ase1p promotes spindle elongation.

Cells use a finely tuned cooperative localization mechanism that exploits differences in the geometry and concentration of ase1p binding sites along single and overlapping microtubules.
Title: Microtubule-driven multimerization recruits ase1p onto overlapping microtubules.
