| tubulin | <cell biology, protein> Abundant cytoplasmic protein (55 kD), found mainly in two forms, _ and _. A tubulin heterodimer (one _, one _), constitutes the protomer for microtubule assembly. Multiple copies of tubulin genes are present (and are expressed) in most eukaryotic cells studied so far. The different tubulin isoforms seem, however, to be functionally equivalent. _ _ tubulin is localised in centrosome and is involved in nucleation of microtubule assembly during the cell cycle. Highly conserved from yeast to mammals. (18 Nov 1997) |
| tubulin-tyrosine ligase | <enzyme> An enzyme that covalently links a tyrosine to the C-terminal glutamyl residue of tubulin, coupled with the hydrolysis of ATP to ADP and Pi; this is a unique posttranslational modification that may have a significant role in cytoskeletal traffic and design.

| tubulina | A suborder of ameboid protozoa characterised by a branched or unbranched cylindrical body and the absence of bidirectional cytoplasmic flow. Nuclear division is mesomitotic. (12 Dec 1998) |
