tubulin

 [too´bu-lin]
the constituent protein of microtubules; thought to be involved in phagocyte motility.

tu·bu·lin

(tū'byū-lin),
A protein subunit of microtubules; it is a dimer composed of two globular polypeptides, α-tubulin and β-tubulin.
See also: dynein.

tubulin

A contractile protein that forms microtubules. These form the spindle fibres in MITOSIS that draw chromosomes apart is the course of cell division.

tubulin

a globular protein molecule, similar to ACTIN, that is the building block of microtubules within the cytoplasm of cells.

tubulin

the constituent protein of microtubules of cells which provide a skeleton for maintaining cell shape and is thought to be involved in cell motility.

α-tubulin
with β-tubulins contributes to the heterodimer tubulin, the building blocks of the electron microscopically visible cell components, the microtubules.
β-tubulin
one of the monomeric globular proteins which associate to form the dimer, α,β-tubulin, the basis of microfilaments.
