Dynamics of Intracellular Nano-Transport by Kinesins [PDF]
, 2015 Transport in neurons is realized by motor proteins (kinesins) which walk along intracellular tracks. Healthy mechanical transport is necessary for neurons to maintain their normal functions.

Catastrophic Kinesins Piecing Together Their Mechanism by 3D Reconstruction
, 2004 Kin Is, kinesins with an internal catalytic domain, de-polymerize microtubules from both ends, and the KIF2C crystal structure presented by Ogawa et al.

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana
Cytoskeleton, EarlyView.ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Mitosis, Microtubule Dynamics and the Evolution of Kinesins
Experimental Cell Research, 2015 All living organisms must transmit genetic information through successive generations, and all six eukaryotic supergroups utilize a mitotic spindle to accomplish this task.

Phylogenetic analysis of the kinesin superfamily from Physcomitrella
Frontiers in Plant Science, 2012 Kinesins are an ancient superfamily of microtubule dependent motors. They participate in an ex-tensive and diverse list of essential cellular functions, including mitosis, cytokinesis, cell polari-zation, cell elongation, flagellar development, and ...

Proceedings of the National Academy of Sciences, 2004 We have identified dimeric kinesin mutants that become stalled on the microtubule after one ATP turnover, unable to bind and hydrolyze ATP at their second site. We have used these mutants to determine the regulatory signal that allows ATP to bind to the forward head, such that processive movement can continue.

Cytoskeleton, EarlyView.ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Regulatory Mechanisms that Control Mitotic Kinesins
Experimental Cell Research, 2015 During mitosis, the mitotic spindle is assembled to align chromosomes at the spindle equator in metaphase, and to separate the genetic material equally to daughter cells in anaphase.

Making Two out of One: Kinesin Motors Driving Plant Cell Division
Cytoskeleton, EarlyView.ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...

, 2017 We investigated the role of the concentration of microtubules and depletion force in the emergence of collective motion of microtubules driven by kinesins.
