The alpha-tubulin (relative molecular weight about 50kD) is globular protein that exists in
cells as part of soluble alpha/beta-tubulin dimer or it is polymerized into microtubules. In
different species it is coded by multiple tubulin genes that form tubulin classes (in human 6
genes). Expressed tubulin genes are named tubulin isotypes. Some of the tubulin isotypes
are expressed ubiquitously, while some have more restricted tissue expression.
Alpha-tubulin is also subject of numerous post-translational modifications. Tubulin isotypes
and their posttranslational modifications are responsible for multiple tubulin charge variants -
tubulin isoforms. Heterogeneity of alpha-tubulin is concentrated in C-terminal structural
domain.The microtubules are intracellular dynamic polymers made up of evolutionarily conserved polymorphic alpha/beta-tubulin heterodimers and a large number of microtubule-associated proteins (MAPs). The microtubules consist of 13 protofilaments and
have an outer diameter 25nm. Microtubules have their intrinsic polarity; highly dynamic plus
ends and less dynamic minus ends. Microtubules are required for vital processes in eukaryotic cells including mitosis, meiosis, maintenance of cell shape and intracellular transport. Microtubules are also necessary for movement of cells by means of flagella and cilia. In mammalian tissue culture cells microtubules have their minus ends anchored in microtubule organizing centers (MTOCs).The GTP (guanosintriphosphate) molecule is an essential for tubulin heterodimer to associate with other heterodimers to form microtubule. In vivo, microtubule dynamics vary considerably. Microtubule polymerization is reversible and a populations of microtubules in cells are on their minus ends either growing or shortening this phenomenon is called dynamic instability of microtubules. On a practical level, microtubules can easily be stabilized by the addition of non-hydrolysable analogues of GTP (eg. GMPPCP) or more commonly by anti-cancer drugs such as Taxol. Taxol stabilizes microtubules at room temperature for many hours. Using limited proteolysis by enzymes both tubulin subunits can be divided into N-terminal and C-terminal structural domains.
