CC -!- FUNCTION: Tubulin is the major constituent of microtubules. It CC binds two moles of GTP, one at an exchangeable site on the beta CC chain and one at a non-exchangeable site on the alpha chain. CC -!- SUBUNIT: Dimer of alpha and beta chains. A typical microtubule is CC a hollow water-filled tube with an outer diameter of 25 nm and an CC inner diameter of 15 nM. Alpha-beta heterodimers associate head- CC to-tail to form protofilaments running lengthwise along the CC microtubule wall with the beta-tubulin subunit facing the CC microtubule plus end conferring a structural polarity. CC Microtubules usually have 13 protofilaments but different CC protofilament numbers can be found in some organisms and CC specialized cells. CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton. CC -!- TISSUE SPECIFICITY: Ubiquitously expressed with highest levels in CC spleen, thymus and immature brain. CC -!- PTM: Some glutamate residues at the C-terminus are polyglycylated, CC resulting in polyglycine chains on the gamma-carboxyl group. CC Glycylation is mainly limited to tubulin incorporated into CC axonemes (cilia and flagella) whereas glutamylation is prevalent CC in neuronal cells, centrioles, axonemes, and the mitotic spindle. CC Both modifications can coexist on the same protein on adjacent CC residues, and lowering polyglycylation levels increases CC polyglutamylation, and reciprocally. The precise function of CC polyglycylation is still unclear. {ECO:0000269|PubMed:19524510}. CC -!- PTM: Some glutamate residues at the C-terminus are CC polyglutamylated, resulting in polyglutamate chains on the gamma- CC carboxyl group (PubMed:1967194, PubMed:15890843). CC Polyglutamylation plays a key role in microtubule severing by CC spastin (SPAST). SPAST preferentially recognizes and acts on CC microtubules decorated with short polyglutamate tails: severing CC activity by SPAST increases as the number of glutamates per CC tubulin rises from one to eight, but decreases beyond this CC glutamylation threshold (By similarity). CC {ECO:0000250|UniProtKB:Q71U36, ECO:0000269|PubMed:15890843, CC ECO:0000269|PubMed:1967194}. CC -!- PTM: Undergoes a tyrosination/detyrosination cycle, the cyclic CC removal and re-addition of a C-terminal tyrosine residue by the CC enzymes tubulin tyrosine carboxypeptidase (TTCP) and tubulin CC tyrosine ligase (TTL), respectively. CC {ECO:0000250|UniProtKB:P68370}. CC -!- PTM: Acetylation of alpha chains at Lys-40 stabilizes microtubules CC and affects affinity and processivity of microtubule motors. This CC modification has a role in multiple cellular functions, ranging CC from cell motility, cell cycle progression or cell differentiation CC to intracellular trafficking and signaling (By similarity). CC {ECO:0000250|UniProtKB:P41351}. CC -!- SIMILARITY: Belongs to the tubulin family. {ECO:0000305}.
