Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin. Actin filaments are the smallest type, with a ...

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 ...

Microtubules are protein fibers that facilitate the transport of cellular components throughout a cell’s interior. Within a cell, microtubules span from the nucleus to the cell membrane, and the motor ...

Microtubules are major components of the cytoskeleton. They are found in all eukaryotic cells, and they are involved in mitosis, cell motility, intracellular transport, and maintenance of cell shape.

The image is a time projection of mitochondria (in the cytoplasm, grey) and chromosomes (center of the cell, orange) during anaphase showing a flow pattern with vortexes. The flow pattern is aligned ...

Protein filaments, like microtubules, and molecular motors are fundamental components of the cytoskeleton in many types of cells. An important example of the construction and rebuilding of ...
