Noun
(biochemistry) Any of a group of proteins used as the material for microtubules.
(biochemistry) Specifically, the dimer of α-tubulin and β-tubulin.
Source: en.wiktionary.orgGTP-bound tubulin can begin adding to the tip of the microtubule again, providing a new cap and protecting the microtubule from shrinking. Source: Internet
During polymerization, the tubulin dimers are in the GTP -bound state. Source: Internet
Each tubulin also has a tail extending out from the microtubules, which is negatively charged, and therefore attracts positively charged ions. Source: Internet
However, in most microtubules there is a seam in which tubulin subunits interact α-β. citation Some species of Prosthecobacter also contain microtubules. Source: Internet
In the gel state, it was further hypothesized that the water electrical dipoles are oriented in the same direction, along the outer edge of the microtubule tubulin subunits. Source: Internet
It has anti-microtubule activity, and its mechanism is similar to that of vinca alkaloids in that they bind to tubulin, inhibiting microtubule formation. Source: Internet
