Intraflagellar transport protein 27 homolog (IFT27)

Small GTPase-like part of the intraflagellar transport (IFT) complex B that promotes the exit of the BBSome complicated from cilia via its interaction with ARL6 (PubMed:25443296). Not included in entry of this BBSome complicated into cilium.

Required for hedgehog signaling. Forms a subcomplex within the IFT complex B with IFT25.
