What is the purpose of the molecular weight marker? Functions of plant γ‐tubulin remain to be determined. Tubulin. Tubulins are highly and stably expressed and conserved across species. The self-assembly of tubulin leads to microtubules, hollow cylinders that are one of the major components of the eukaryotic cytoskeleton. 3, the tau factor inhibits colchicine binding to tubulin very efficiently; tau factor did not modify the Cmax, but markedly decreased the KA. These subunits are slightly acidic with an isoelectric point between 5.2 and 5.8. The model presented by Nogales, Wolf, and Downing, shows that each tubulin monomer -- the alpha and the beta -- is a compact molecular structure with three functional components or domains, one that binds to nucleotides, one that binds to drugs like taxol, and one that looks to be a binding site for other proteins. Instead, MAP-2 and a 180 kDa protein with characteristics of MAP-3 remained associated to the polymer after the assembly. Methods Cell Biol 36, 581-605. The tubulin protein appears as a single species migrating at ~55 kDa. both rDNA and β-tubulin sequences, nucleotide variation within isolates of G. frondosa (5.4% in rDNA and 12.2% in β-tubulin) was relatively small compared to that observed between isolates of G. frondosa and G. sordulenta (14.3% in rDNA and 30.2% in β-tubulin). Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.
