Intraflagellar transport protein 56 (TTC26)

Component of the intraflagellar transport (IFT) complex B necessary for transport of proteins in the motile cilium. Required for transport of specific ciliary cargo proteins associated with motility, while it is neither required for IFT complex B assembly or motion nor for cilium assembly.

Required for efficient coupling between the accumulation of GLI3 at the ciliary tip and its dissociation from SUFU. .
