+ | [https://www.uniprot.org/uniprot/D0VWZ0_SHEEP D0VWZ0_SHEEP] 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).[RuleBase:RU003505][SAAS:SAAS023123_004_019801] | ||

+ | == Publication Abstract from PubMed == | ||
+ | The typical function of kinesins is to transport cargo along microtubules. Binding of ATP to microtubule-attached motile kinesins leads to cargo displacement. To better understand the nature of the conformational changes that lead to the power stroke that moves a kinesin's load along a microtubule, we determined the X-ray structure of human kinesin-1 bound to alphabeta-tubulin. The structure defines the mechanism of microtubule-stimulated ATP hydrolysis, which releases the kinesin motor domain from microtubules. It also reveals the structural linkages that connect the ATP nucleotide to the kinesin neck linker, a 15-amino acid segment C terminal to the catalytic core of the motor domain, to result in the power stroke. ATP binding to the microtubule-bound kinesin favors neck-linker docking. This biases the attachment of kinesin's second head in the direction of the movement, thus initiating each of the steps taken. | ||
