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.

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.

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.

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.

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.

Basal body and flagellum mutants reveal a rotational constraint of the central pair microtubules in the axonemes of trypanosomes. [PDF]
, 2006 Productive beating of eukaryotic flagella and cilia requires a strict regulation of axonemal dynein activation. Fundamental to any description of axonemal beating is an understanding of the significance of the central pair microtubules and the degree to ...

A "MICROTUBULE" IN A BACTERIUM [PDF]
The Journal of Cell Biology, 1967 A study of the anchorage of the flagella in swarmers of Proteus mirabilis led to the incidental observation of microtubules. These microtubules were found in thin sections and in whole mount preparations of cells from which most of the content had been released by osmotic shock before staining negatively with potassium phosphotungstate (PTA).
