CC -!- FUNCTION: Tubulin is the major constituent of microtubules. It binds
CC two moles of GTP, one at an exchangeable site on the beta chain and one
CC at a non-exchangeable site on the alpha chain.
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.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton.
CC -!- MISCELLANEOUS: There are nine genes coding for beta-tubulin.
CC -!- SIMILARITY: Belongs to the tubulin family. {ECO:0000305}.
