Previous GeneCards Identifiers for BBS5 Gene
This gene encodes a protein that has been directly linked to Bardet-Biedl syndrome. The primary features of this syndrome include retinal dystrophy, obesity, polydactyly, renal abnormalities and learning disabilities. Experimentation in non-human eukaryotes suggests that this gene is expressed in ciliated cells and that it is required for the formation of cilia. Alternate transcriptional splice variants have been observed but have not been fully characterized. [provided by RefSeq, Jul 2008]
GeneCards Summary for BBS5 Gene
BBS5 (Bardet-Biedl Syndrome 5) is a Protein Coding gene. Diseases associated with BBS5 include bardet-biedl syndrome 5 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 phosphatidylinositol-3-phosphate binding. An important paralog of this gene is ENSG00000251569.
UniProtKB/Swiss-Prot for BBS5 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 BBSome complex ciliary localization but not for the proper complex assembly.
