Mutations in this gene have been observed in patients with the major form (type 1) of Bardet-Biedl syndrome. The encoded protein may play a role in eye, limb, cardiac and reproductive system development. [provided by RefSeq, Jul 2008]
GeneCards Summary for BBS1 Gene
BBS1 (Bardet-Biedl Syndrome 1) is a Protein Coding gene. Diseases associated with BBS1 include bardet-biedl syndrome 1 and bardet-biedl syndrome. Among its related pathways are Organelle biogenesis and maintenance and Cargo trafficking to the periciliary membrane. GO annotations related to this gene include RNA polymerase II repressing transcription factor binding and smoothened binding. An important paralog of this gene is ENSG00000256349.
UniProtKB/Swiss-Prot for BBS1 Gene
The BBSome complex is thought to function as a coat complex required for sorting of specific membrane proteins to the primary cilia. 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. The BBSome complex, together with the LTZL1, controls SMO ciliary trafficking and contributes to the sonic hedgehog (SHH) pathway regulation. Required for proper BBSome complex assembly and its ciliary localization.
