General annotation (Comments)
| Function | May be required for the dynein-mediated transport of pericentriolar proteins to the centrosome. Required for microtubule anchoring at the centrosome but not for microtubule nucleation. The BBSome complex is required for ciliogenesis but is dispensable for centriolar satellite function. This ciliogenic function is mediated in part by the Rab8 GDP/GTP exchange factor, which localizes to the basal body and contacts the BBSome. Rab8(GTP) enters the primary cilium and promotes extension of the ciliary membrane. Firstly the BBSome associates with the ciliary membrane and binds to RAB3IP/Rabin8, the guanosyl exchange factor (GEF) for Rab8 and then the Rab8-GTP localizes to the cilium and promotes docking and fusion of carrier vesicles to the base of the ciliary membrane. Ref.6 Ref.8 |
| Subunit structure | Part of BBSome complex, that contains BBS1, BBS2, BBS4, BBS5, BBS7, BBS8, BBS9 and BBIP10. The BBSome complex binds to PCM1 and tubulin. Interacts with DCTN1. Interacts with CCDC28B. Ref.5 Ref.6 Ref.8 |
| Subcellular location | Cytoplasm › cytoskeleton › centrosome. Cytoplasm › cytoskeleton. Cell projection › cilium membrane. Cytoplasm. Note: Localizes to the pericentriolar region throughout the cell cycle. Centrosomal localization requires dynein. Localizes to nonmembranous centriolar satellites in the cytoplasm. Ref.6 Ref.8 |
| Tissue specificity | Ubiquitously expressed. The highest level of expression is found in the kidney. |
| Involvement in disease | Bardet-Biedl syndrome 4 (BBS4) [MIM:209900]: A syndrome characterized by usually severe pigmentary retinopathy, early-onset obesity, polydactyly, hypogenitalism, renal malformation and mental retardation. Secondary features include diabetes mellitus, hypertension and congenital heart disease. Bardet-Biedl syndrome inheritance is autosomal recessive, but three mutated alleles (two at one locus, and a third at a second locus) may be required for clinical manifestation of some forms of the disease. |
| Sequence similarities | Belongs to the BBS4 family. Contains 10 TPR repeats. |
