Tubulin
Videos
Tubulin in molecular biology can refer either to the tubulin protein superfamily of globular proteins, or one of the member proteins of that superfamily. α- and β-tubulins polymerize into microtubules

Microtubule
Videos
Microtubules are biopolymers of tubulin that form part of the cytoskeleton to provide structure and shape to a eukaryotic cell. Microtubules can be as long as 50 micrometres, as wide as 23 to 27 nm an

…either to the tubulin protein superfamily of globular proteins, or one of the member proteins of that superfamily. α- and β-tubulins polymerize into microtubules, a major component of the eukaryotic cytoskeleton. It was discovered and named by Hideo Mōri in 1968. Microtubules function in many essential cellular…

Microtubules are one of the cytoskeletal filament systems in eukaryotic cells. The microtubule cytoskeleton is involved in the transport of material within cells, carried out by motor proteins that move on the surface of the microtubule.
