Group II Heat Shock Protein 60 chaperonins are paralogous subunits that assemble to form a multi-subunit ring complex, the Chaperonin Containing TCP-1 (CCT) complex. Within the cytosol, the CCT complex catalyses the ATP-dependent folding of approximately 10% of newly synthesized proteins. (Adapted from
