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

Microtubules are composed of alphabeta-tubulin heterodimers, and drugs that interfere with microtubule dynamics are used widely in cancer chemotherapy. Small synthetic molecules with an indole nucleus as a core structure have been identified as microtubule inhibitors and recognized as anticancer agents. However, structural information for the interactions between indole derivatives and tubulin is sparse. Here, we present the 2.55 A crystal structure of tubulin in complex with the indole derivative D64131. We compare the binding modes of D64131, colchicine, and five other indole derivatives to tubulin. These results reveal the interactions between the indole derivatives and tubulin, explain previous results of structure-activity-relationship (SAR) studies and, thus, provide insights into the development of new indole derivatives targeting the colchicine binding site.
