Publication Abstract from PubMed

The chaperonin containing TCP-1 (CCT, also known as TRiC) is the only member of the chaperonin family found in the cytosol of eukaryotes. Like other chaperonins, it assists the folding of newly synthesised proteins. It is, however, unique in its specificity towards only a small subset of non-native proteins. We determined two crystal structures of mouse CCTgamma apical domain at 2.2 A and 2.8 A resolution. They reveal a surface patch facing the inside of the torus that is highly evolutionarily conserved and specific for the CCTgamma apical domain. This putative substrate-binding region consists of predominantly positively charged side-chains. It suggests that the specificity of this apical domain towards its substrate, partially folded tubulin, is conferred by polar and electrostatic interactions. The site and nature of substrate interaction are thus profoundly different between CCT and its eubacterial homologue GroEL, consistent with their different functions in general versus specific protein folding assistance.
