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   -!- PTM: Undergoes a tyrosination/detyrosination cycle, the cyclic removal
CC       and re-addition of a C-terminal tyrosine residue by the enzymes tubulin
CC       tyrosine carboxypeptidase (TTCP) and tubulin tyrosine ligase (TTL),
CC       respectively. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the tubulin family. {ECO:0000305}.
