Distinct functions of the kinesin-9 family in mammalian motile cilia

Ciliary beat and intraflagellar transport (IFT) depend on dynein and kinesin motors. Kinesin-9 family members Kif6 and Kif9 are implicated in ciliary motilities across protists and mammals. How they function and whether they act redundantly, however, remain unclear. Here, we show that they play distinct roles in mammals. Kif6 forms... Show more
