  • 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 αβ-tubulin. The structure defines the mechanism of microtubule-stimulated ATP hydrolysis, which releases the kinesin motor domain from… CONTINUE READING
