Function

[TBA1B_BOVIN] 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. [STMN4_RAT] Exhibits microtubule-destabilizing activity.^[1] ^[2] ^[3] [TBB2B_BOVIN] 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 (By similarity).

Publication Abstract from PubMed

Microtubule-stabilizing agents (MSAs) are efficacious chemotherapeutic drugs widely used for the treatment of cancer. Despite the importance of MSAs for medical applications and basic research, their molecular mechanisms of action on tubulin and microtubules remain elusive. Here, we determined high-resolution crystal structures of alphabeta-tubulin in complex with two unrelated MSAs, zampanolide and epothilone A. Both compounds were bound to the taxane-pocket of beta-tubulin and used their respective side chain to induce structuring of the M-loop into a short helix. Because the M-loop establishes lateral tubulin contacts in microtubules, these findings explain how taxane-site MSAs promote microtubule assembly and stability. They further offer fundamental structural insights into the control mechanisms of microtubule dynamics.
