Electrostatically biased binding of kinesin to microtubules. [PDF]
The minimum motor domain of kinesin-1 is a single head. Recent evidence suggests that such minimal motor domains generate force by a biased binding mechanism, in which they preferentially select binding sites on the microtubule that lie ahead in the ...

Single‐headed mode of kinesin‐5 [PDF]
In most organisms, kinesin‐5 motors are essential for mitosis and meiosis, where they crosslink and slide apart the antiparallel microtubule half‐spindles. Recently, it was shown using single‐molecule optical trapping that a truncated, double‐headed human kinesin‐5 dimer can step processively along microtubules.

The kinesin-5 tail domain directly modulates the mechanochemical cycle of the motor domain for anti-parallel microtubule sliding [PDF]
Kinesin-5 motors organize mitotic spindles by sliding apart microtubules. They are homotetramers with dimeric motor and tail domains at both ends of a bipolar minifilament.

The Kinesin-12 Kif15 is a processive track-switching tetramer [PDF]
Kinesin-12 motors are a little studied branch of the kinesin superfamily with the human protein (Kif15) implicated in spindle mechanics and chromosome movement.

Mitotic Motors: Kinesin-5 Takes a Brake [PDF]
A kinesin-5-dependent 'sliding filament' mechanism is commonly used to actively push apart the poles during mitotic spindle assembly and elongation, but a recent study now shows that, in C. elegans, kinesin-5 is deployed as a brake to slow down spindle-pole separation.

Kinesin-5 Eg5 is essential for spindle assembly and chromosome alignment of mouse spermatocytes [PDF]
Background Microtubule organization is essential for bipolar spindle assembly and chromosome segregation, which contribute to genome stability. Kinesin-5 Eg5 is known to be a crucial regulator in centrosome separation and spindle assembly in mammalian ...

Kinesin-5 Is Essential for Growth-Cone Turning [PDF]
Inhibition of kinesin-5, a mitotic motor protein also expressed in neurons, causes axons to grow faster as a result of alterations in the forces on microtubules (MTs) in the axonal shaft. Here, we investigate whether kinesin-5 plays a role in growth-cone guidance. Growth-cone turning requires that MTs in the central (C-) domain enter the peripheral (P-)

Suppressor Analysis Uncovers That MAPs and Microtubule Dynamics Balance with the Cut7/Kinesin-5 Motor for Mitotic Spindle Assembly in Schizosaccharomyces pombe [PDF]
The Kinesin-5 motor Cut7 in Schizosaccharomyces pombe plays essential roles in spindle pole separation, leading to the assembly of bipolar spindle. In many organisms, simultaneous inactivation of Kinesin-14s neutralizes Kinesin-5 deficiency.

Force Dependence of Velocity and Run Length of Kinesin-1, Kinesin-2 and Kinesin-5 Family Molecular Motors [PDF]
Kinesin-1, kinesin-2 and kinesin-5 are three families of a superfamily of motor proteins; which can walk processively on microtubule filaments by hydrolyzing ATP. It was experimentally shown that while the three kinesin dimers show similar feature on the

Human kinesin-5 KIF11 drives the helical motion of anti-parallel and parallel microtubules around each other [PDF]
During mitosis, motor proteins and microtubule-associated protein organize the spindle apparatus by cross-linking and sliding microtubules. Kinesin-5 plays a vital role in spindle formation and maintenance, potentially inducing twist in the spindle ...
