Summary: The protein encoded by this gene is part of a complex that is involved in membrane trafficking. The encoded protein is a molecular chaperone that aids in protein folding upon ATP hydrolysis. This protein also plays a role in adipocyte differentiation. Defects in this gene are a cause of Bardet-Biedl syndrome type 12. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, May 2010]
Expression: Broad expression in thyroid (RPKM 5.9), testis (RPKM 4.6) and 22 other tissues See more

Using sequence analysis, the role of BBS6, 10 and 12 was assessed in a Bardet-Biedl syndrome patient population comprising 93 cases from 74 families.
Title: Mutations in chaperonin-like BBS genes are a major contributor to disease development in a multiethnic Bardet-Biedl syndrome patient population.
the BBS10 and BBS12 proteins are located within the basal body of this primary cilium and inhibition of their expression impairs ciliogenesis, activates the GSK3 pathway, and induces PPAR nuclear accumulation, hence favoring adipogenesis
Title: Transient ciliogenesis involving Bardet-Biedl syndrome proteins is a fundamental characteristic of adipogenic differentiation.
BBS12 accounts for approximately 5% of all BBS cases and defines a novel branch of the type II chaperonin superfamily

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
