Figure 7


Fig. 7. IFT57 and IFT20 mediate the ATP-dependent dissociation of kinesin. (A) A model describing the nature of protein interactions within the IFT complex. IFT57 tethers IFT20 to the IFT particle, while kinesin binds to the IFT particle through an unknown entity. IFT20 physically interacts with KIF3B and mediates the ATP-dependent dissociation of kinesin. (B) In the absence of IFT57, IFT20 can no longer associate with the IFT particle. However, the interaction of kinesin with the IFT particle is stabilized by loss of IFT57 and IFT20 from the IFT particle.
