CC -!- FUNCTION: The BBSome complex is thought to function as a coat complex
CC required for sorting of specific membrane proteins to the primary
CC cilia. The BBSome complex is required for ciliogenesis but is
CC dispensable for centriolar satellite function. This ciliogenic function
CC is mediated in part by the Rab8 GDP/GTP exchange factor, which
CC localizes to the basal body and contacts the BBSome. Rab8(GTP) enters
CC the primary cilium and promotes extension of the ciliary membrane.
CC Firstly the BBSome associates with the ciliary membrane and binds to
CC RAB3IP/Rabin8, the guanosyl exchange factor (GEF) for Rab8 and then the
CC Rab8-GTP localizes to the cilium and promotes docking and fusion of
CC carrier vesicles to the base of the ciliary membrane. The BBSome
CC complex, together with the LTZL1, controls SMO ciliary trafficking and
CC contributes to the sonic hedgehog (SHH) pathway regulation. Required
CC for BBSome complex ciliary localization but not for the proper complex
CC assembly. {ECO:0000256|ARBA:ARBA00054242,
CC ECO:0000256|PIRNR:PIRNR010072}.
CC -!- SUBUNIT: Part of BBSome complex, that contains BBS1, BBS2, BBS4, BBS5,
CC BBS7, BBS8/TTC8, BBS9 and BBIP10. {ECO:0000256|PIRNR:PIRNR010072}.
CC -!- SUBCELLULAR LOCATION: Cell projection, cilium membrane
CC {ECO:0000256|ARBA:ARBA00004309, ECO:0000256|PIRNR:PIRNR010072}.
CC Cytoplasm, cytoskeleton, microtubule organizing center, centrosome,
CC centriolar satellite {ECO:0000256|ARBA:ARBA00004607}.
CC -!- SIMILARITY: Belongs to the BBS5 family. {ECO:0000256|ARBA:ARBA00005822,
CC ECO:0000256|PIRNR:PIRNR010072}.
