Actin–Microtubule Crosstalk Imparts Stiffness to the Contractile Ring in Fission Yeast

Cells, 2023
Actin–microtubule interactions are critical for cell division, yet how these networks of polymers mutually influence their mechanical properties and functions in live cells remains unknown.

Simulation of microtubule–cytoplasm interaction revealed the importance of fluid dynamics in determining the organization of microtubules

Plant Direct, 2023
Although microtubules in plant cells have been extensively studied, the mechanisms that regulate the spatial organization of microtubules are poorly understood.

Investigation of the Electrical Properties of Microtubule Ensembles under Cell-Like Conditions

Nanomaterials, 2020
Microtubules are hollow cylindrical polymers composed of the highly negatively-charged (~23e), high dipole moment (1750 D) protein α, β- tubulin.

Ectopic A-lattice seams destabilize microtubules [PDF]

, 2014
Natural microtubules typically include one A-lattice seam within an otherwise helically symmetric B-lattice tube. It is currently unclear how A-lattice seams influence microtubule dynamic instability.

The flagella connector of Trypanosoma brucei : an unusual mobile transmembrane junction. [PDF]

, 2004
Throughout its elongation, the new flagellum of the procyclic form of the African trypanosome Trypanosoma brucei is tethered at its tip to the lateral aspect of the old flagellum.

Actin–microtubule coordination at growing microtubule ends [PDF]

Nature Communications, 2014
To power dynamic processes in cells, the actin and microtubule cytoskeletons organize into complex structures. Although it is known that cytoskeletal coordination is vital for cell function, the mechanisms by which cross-linking proteins coordinate actin and microtubule activities remain poorly understood.

Regulation of cell migration by dynamic microtubules [PDF]

, 2011
Microtubules define the architecture and internal organization of cells by positioning organelles and activities, as well as by supporting cell shape and mechanics. One of the major functions of microtubules is the control of polarized cell motility.

Sulfo-SMCC Prevents Annealing of Taxol-Stabilized Microtubules In Vitro. [PDF]

PLoS ONE, 2016
Microtubule structure and functions have been widely studied in vitro and in cells. Research has shown that cysteines on tubulin play a crucial role in the polymerization of microtubules.

S. pombe kinesins-8 promote both nucleation and catastrophe of microtubules [PDF]

, 2012
The kinesins-8 were originally thought to be microtubule depolymerases, but are now emerging as more versatile catalysts of microtubule dynamics. We show here that S.

Structural intermediates in the assembly of taxoid-induced microtubules and GDP-tubulin double rings: time-resolved X-ray scattering [PDF]

, 1996
We have studied the self-association reactions of purified GDP-liganded tubulin into double rings and taxoid-induced microtubules, employing synchrotron time-resolved x-ray solution scattering.
