The function of BBS12 (Bardet-Biedl syndrome 12, ENSG00000181004) is as follows. Component of the chaperonin-containing T-complex (TRiC), a molecular chaperone complex that assists the folding of proteins upon ATP hydrolysis. As part of the TRiC complex may play a role in the assembly of BBSome, a complex involved in ciliogenesis regulating transports vesicles to the cilia (PubMed:20080638). Involved in adipogenic differentiation (PubMed:19190184). .
