Figure 4. A model for XBX-1::YFP anterograde transport in C. elegans sensory cilia.

Figure 4

(A) In wild type, XBX-1::YFP, likely associated with an IFT-dynein heavy chain, is transported separately from IFT particles by the coordinate action of the two IFT anterograde motors, kinesin-II and OSM-3, in the middle segment and by OSM-3 alone in the distal segment. (B) In bbs mutants, the transport of XBX-1::YFP is the same as in wild type, while the two IFT-A and IFT-B subcomplexes are separated and transported by kinesin-II and OSM-3, respectively.
