Kinesin is a microtubule-dependent motor protein. We have recently determined the X-ray structure of monomeric and dimeric kinesin from rat brain. The dimer consists of two motor domains, held together by their α-helical neck domains forming a coiled coil. Here we analyze the nature of the interacti...
