RA Moepps B., Maucher H.P., Bogenberger J.M., Schraudolf H.; RT "Characterization of the alpha and beta tubulin gene families from Anemia RT phyllitidis L.Sw."; RL Submitted (APR-1993) to the EMBL/GenBank/DDBJ databases. 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 -!- SIMILARITY: Belongs to the tubulin family. {ECO:0000305}.
