Synonyms:RABL4, RAYL Background:Small GTPase-like component of the intraflagellar transport(IFT) complex B that promotes the exit of the BBSome complex from cilia via its interaction with ARL6(PubMed:25443296). Not involved in entry of the BBSome complex into cilium. Prevents aggregation of GTP-free ARL6(PubMed:25443296). Required for hedgehog signaling. Forms a subcomplex within the IFT complex B with IFT25(By similarity).
