BBIP1 gene

BBSome interacting protein 1

The information on this page was automatically extracted from online scientific databases.

From NCBI Gene:

This gene encodes one of eight proteins that form the BBSome complex and is essential for its assembly. The BBSome complex is involved in trafficking signal receptors to and from the cilia. Mutations in this gene result in Bardet-Biedl syndrome 18. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]

From UniProt:

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. Required for primary cilia assembly and BBSome stability. Regulates cytoplasmic microtubule stability and acetylation.

  • Bardet-Biedl syndrome 18

From UniProt:

Bardet-Biedl syndrome 18 (BBS18): 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.
