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 (PubMed:6504138, PubMed:2207090,
CC PubMed:7704569). Microtubules grow by the addition of GTP-tubulin
CC dimers to the microtubule end, where a stabilizing cap forms. Below the
CC cap, tubulin dimers are in GDP-bound state, owing to GTPase activity of
CC alpha-tubulin (PubMed:6504138, PubMed:2207090, PubMed:7704569).

CC -!- SUBUNIT: Dimer of alpha and beta chains (PubMed:6504138,
CC PubMed:2207090, PubMed:7704569). A typical microtubule is a hollow
CC water-filled tube with an outer diameter of 25 nm and an inner diameter
CC of 15 nM. Alpha-beta heterodimers associate head-to-tail to form
CC protofilaments running lengthwise along the microtubule wall with the
CC 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|ARBA:ARBA00034322}.
