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. CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton. CC -!- TISSUE SPECIFICITY: Alpha-3 and alpha-7 are identical but coded by CC two different genes, they are testis-specific. 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 (By similarity). CC -!- PTM: Some glutamate residues at the C-terminus are either CC polyglutamylated or polyglycylated. These 2 modifications occur CC exclusively on glutamate residues and result in either CC polyglutamate or 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 such CC modifications is still unclear but they are regulate the assembly CC and dynamics of axonemal microtubules. 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 -!- SIMILARITY: Belongs to the tubulin family.
