Function
[TBA1B_PIG] Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain. [KI10A_DROME] Required during anaphase to drive sister chromatid separation to promote flux by actively depolymerizing kinetochore microtubules at their pole-associated minus ends, thereby moving chromatids through a "poleward flux".[1] [F2Z5B2_PIG] Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain.[RuleBase:RU003505]
