An ATP-gate controls tubulin binding by the tethered head of kinesin-1
Kinesin-1 is a 2-headed molecular motor that walks along microtubules, with each step gated by ATP binding. Existing models for the gating mechanism propose a role for the microtubule lattice. We show that unpolymerised tubulin binds to kinesin-1, causing tubulin-activated ADP release. With no added...
