Tubulin is the protein which makes up microtubules. Microtubules are assembled from dimers of α- and β-tubulin. Each of these subunits has three domains.

tubulins The protein subunits from which microtubules are assembled.
tumor suppressor genes Genes that normally keep cell division under control, preventing the cell from responding to internal and external commands to divide.
tubulin - protein which when polymerized forms microtubules, necessary for (among other processes) karyokinesis.
tubulin Globular protein forming the hollow cylinder of microtubules.
tumor necrosis factor. A cytokine, the most important source of which is macrophages, that is a major mediator of inflammation.
are variable in length but can grow 1000 times as long as they are wide;
are built by the assembly of dimers of alpha tubulin and beta tubulin;
are found in both animal and plant cells.

In most NFT-bearing neurons, we observed a strong reduction in acetylated a-tubulin immunoreactivity (a marker of stable microtubules) and a reduction of the in situ hybridization signal for tubulin mRNA.
Although all eukaryotes contain the common cytoskeletal elements actin and tubulin (both free in the cytoplasm and polymerized in the form of microfilaments and microtubules), intermediate filaments are found only in some metazoan species, ...
The tubulin protein subunits of microtubules associate in a cylindrical arrangement. Microtubules form from centrioles and basal bodies. These are short microtubular structures at the base of the spindle and flagella and cilia, respectively.
They are made of a protein called tubulin. Tubulin dimers are arranged to form a long hollow cylinder.
The fibers are lengthened and shortened as tubulin dimers assemble or disassemble from one or both ends of the filament.
Dynamic instability A property of microtubules such that some microtubules in a population lengthen while other simultaneously shorten; a result of the random fluctuations in the number of GTP- tubulin subunits or GDP-tubulin subunits at the ...
Microtubules are small hollow cylinders (25 nm in diameter and from 200 nm-25 µm in length). These microtubules are composed of a globular protein tubulin.
Hollow cylinders made of the protein tubulin that form, among other things, the spindle fibers.

A hollow rod of tubulin protein in the cytoplasm of all eukaryotic cells and in cilia, flagella, and the cytoskeleton.

microtubules -- Type of filament in eukaryotic cells composed of units of the protein tubulin. Among other functions, it is the primary structural component of the eukaryotic flagellum.
In particular, he has devised a system that can discriminate among myotubulin-specific regulatory regions, other regulatory regions, and nonregulatory regions.
(Science: cell biology) components from which a structure is built, thus myosin has six subunits, microtubules are built of tubulin subunits. In some cases it may be more informative to speak of protomers.
They are composed of subunits of the protein tubulin--these subunits are termed alpha and beta. Microtubules act as a scaffold to determine cell shape, and provide a set of "tracks" for cell organelles and vesicles to move on.
While microfilaments are thin, microtubules are thick, strong spirals of thousands of subunits. Those subunits are made of the protein called tubulin. And yes, they got their name because they look like a tube.
