Cytoskeleton: A catastrophic kinesin [PDF]
The 'plus' ends of microtubules exhibit dynamic instability, switching stochastically from growth to shortening phases. The first endogenous regulator of such 'catastrophes' has been identified, and is a kinesin-related microtubule motor protein.

Prime movers : mechanochemistry of mitotic kinesins [PDF]
Mitotic spindles are self-organizing protein machines that harness teams of multiple force generators to drive chromosome segregation. Kinesins are key members of these force-generating teams.

Kinetically distinct phases of tau on microtubules regulate kinesin motors and severing enzymes
Tau is an intrinsically disordered protein, which diffuses on microtubules1. In neurodegenerative diseases, collectively termed tauopathies, malfunction of tau and its detachment from axonal microtubules are correlated with axonal degeneration2.

MAP7 family proteins regulate kinesin-1 recruitment and activation
Kinesin-1 is responsible for microtubule-based transport of numerous cellular cargoes. Here, we explored the regulation of kinesin-1 by MAP7 proteins. We found that all four mammalian MAP7 family members bind to kinesin-1. In HeLa cells, MAP7, MAP7D1 and

A standardized kinesin nomenclature [PDF]
In recent years the kinesin superfamily has become so large that several different naming schemes have emerged, leading to confusion and miscommunication. Here, we set forth a standardized kinesin nomenclature based on 14 family designations. The scheme unifies all previous phylogenies and nomenclature proposals, while allowing individual sequence ...

Length-dependent disassembly maintains four different flagellar lengths in Giardia. [PDF]
With eight flagella of four different lengths, the parasitic protist Giardia is an ideal model to evaluate flagellar assembly and length regulation. To determine how four different flagellar lengths are maintained, we used live-cell quantitative imaging ...

Mitotic Kinesins: A Reason to Delve into Kinesin-12 [PDF]
The failure of kinesin-targeting cancer drugs is thought to result from functional redundancy of mitotic kinesins. A new study provides mechanistic insights into kinesin-12 that help to explain its targeting to kinetochore fibers and its ability to compensate for inhibition of kinesin-5.

Heterogeneity in kinesin function [PDF]
The kinesin family proteins are often studied as prototypical molecular motors; a deeper understanding of them can illuminate regulation of intracellular transport. It is typically assumed that they function identically. Here we find that this assumption of homogeneous function appears incorrect: variation among motors’ velocities in vivo and in vitro ...

Kinesins, biomolecular motors moving along microtubules (MTs) in cells, can potentially be utilized as nano-scale transport systems with an inverted gliding assay, in which the MTs glide on a kinesin-coated surface.

Kinesin's backsteps under mechanical load [PDF]
Kinesins move processively toward the plus end of microtubules by hydrolyzing ATP for each step. From an enzymatic perspective, the mechanism of mechanical motion coupled to the nucleotide chemistry is often well explained using a single-loop cyclic ...
