Microtubule

Japanese: microtubule

...These cytoskeletal structures can be identified by a fluorescence microscope by staining cells with fluorescent antibodies prepared using the respective constituent proteins as antigens. (1) Microtubules These hollow fibrous structures are the thickest in the cytoskeleton, measuring 250 nm, and are formed by polymerization of tubulin α and β, the main microtubule proteins. In addition, small amounts of proteins such as τ protein and microtubule-associated proteins (MAPs), which are necessary for the polymerization of microtubules and interactions with other fibrous structures, are added to this structure. ...

From [Tubulin]

...proteins that make up microtubules. Microtubules are tubular filamentous structures with a diameter of 24 nm that are found in almost all cells in the living world and are deeply involved in many physiological phenomena such as flagellar and ciliary movement, formation and maintenance of cell morphology, cell division, and transport within nerve axons.
