Reconstitution reveals motor activation for intraflagellar transport.

ABSTRACT: The human body represents a notable example of ciliary diversification. Extending from the surface of most cells, cilia accomplish a diverse set of tasks. Predictably, mutations in ciliary genes cause a wide range of human diseases such as male infertility and blindness. In Caenorhabditis elegans sensory cilia, this functional diversity appears to be traceable to the differential regulation of the kinesin-2-powered intraflagellar-transport (IFT) machinery. Here we reconstituted the first, to our knowledge, functional multi-component IFT complex that is deployed in the sensory cilia of C. elegans. Our bottom-up approach revealed the molecular basis of specific motor recruitment to the IFT trains. We identified the key component that incorporates homodimeric kinesin-2 into its physiologicall
