Publication Abstract from PubMed

Kinesin-3 KIF1A plays prominent roles in axonal transport and synaptogenesis. KIF1A adopts a monomeric form in vitro but acts as a processive dimer in vivo. The mechanism underlying the motor dimerization is poorly understood. Here, we find that the CC1-FHA tandem of KIF1A exists as a stable dimer. The structure of CC1-FHA reveals that the linker between CC1 and FHA unexpectedly forms a beta-finger hairpin, which integrates CC1 with FHA assembling a CC1-FHA homodimer. More importantly, dissociation of the CC1-FHA dimer unleashes CC1 and the beta-finger, which are both essential for the motor inhibition. Thus, dimerization of the CC1-FHA tandem not only promotes the KIF1A dimer formation but also may trigger the motor activity via sequestering the CC1/beta-finger region. The CC1-FHA tandem likely functions as a hub for controlling the dimerization and activation of KIF1A, which may represent a new paradigm for the kinesin regulation shared by other kinesin-3 motors.
