CC   -!- FUNCTION: Tubulin is the major constituent of microtubules, a cylinder
CC       consisting of laterally associated linear protofilaments composed of
CC       alpha- and beta-tubulin heterodimers. Microtubules grow by the addition
CC       of GTP-tubulin dimers to the microtubule end, where a stabilizing cap
CC       forms. Below the cap, tubulin dimers are in GDP-bound state, owing to
CC       GTPase activity of alpha-tubulin. {ECO:0000256|RuleBase:RU000352}.
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000256|ARBA:ARBA00001946};
CC   -!- SUBUNIT: Dimer of alpha and beta chains. A typical microtubule is a
CC       hollow water-filled tube with an outer diameter of 25 nm and an inner
CC       diameter of 15 nM. Alpha-beta heterodimers associate head-to-tail to
CC       form protofilaments running lengthwise along the microtubule wall with
CC       the beta-tubulin subunit facing the microtubule plus end conferring a
CC       structural polarity. Microtubules usually have 13 protofilaments but
CC       different protofilament numbers can be found in some organisms and
CC       specialized cells. {ECO:0000256|RuleBase:RU000352}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton
CC       {ECO:0000256|ARBA:ARBA00004245}.
CC   -!- SIMILARITY: Belongs to the tubulin family.
