KIF3A is a subunit of Kinesin II that is essential for intraflagellar transport (IFT). It functions as the anterograde motor to deliver ciliary components to the tip where the axoneme is assembled. Disruption of KIF3A has been reported to block mammalian ciliogenesis. Recently KIF3A has been found to localize to the mother centriole and is required for centrioles organization.
