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. Interacts with TFCB. {ECO:0000269|PubMed:16928693}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=1;
CC Comment=A number of isoforms are produced. According to EST
CC sequences.;
CC Name=1;
CC IsoId=P29511-1; Sequence=Displayed;
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 -!- PTM: Acetylation of alpha chains at Lys-40 stabilizes microtubules and
CC affects affinity and processivity of microtubule motors. This
CC modification has a role in multiple cellular functions, ranging from
CC cell motility, cell cycle progression or cell differentiation to
CC intracellular trafficking and signaling (By similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: There are six genes coding for alpha-tubulin.
CC -!- SIMILARITY: Belongs to the tubulin family. {ECO:0000305}.
