All cytoskeletons consist of three major classes of elements that differ in size and in protein composition. Microtubules are the largest type of filament, with a diameter of about 25 nanometers ...

Microtubules are composed of a protein called tubulin, which consists of alpha and beta subunits that assemble into large, tube-shaped filaments within the cell. These fibers are dynamic, growing from ...

In plants, both microtubule-associated proteins (MAPS) and viral movement proteins (MPs) interact with microtubules. Recently, a unique plant structural MAP has been cloned, which may have a ...
