Component of the chaperonin-containing T-complex (TRiC), a molecular chaperone complex that assists the folding of proteins upon ATP hydrolysis.The TRiC complex mediates the folding of WRAP53/TCAB1, thereby regulating telomere maintenance.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.The TRiC complex plays a role in the folding of actin and tubulin.
