TRIC (TCP-1 Ring Complex), also known as CCT (Chaperonin Containing TCP-1), is a eukaryotic molecular chaperone critical for protein folding and cellular proteostasis. Discovered in the 1990s, it belongs to the group II chaperonin family and shares structural similarities with prokaryotic chaperonins like GroEL. However, TRIC is more complex, consisting of two stacked octameric rings, each composed of eight distinct subunits (CCT1 to CCT8). These subunits exhibit sequence divergence, enabling TRIC to recognize a broad spectrum of substrate proteins, particularly those with complex α-helical or β-sheet domains.
TRIC facilitates ATP-dependent folding of ~10% of eukaryotic proteins, including cytoskeletal components like actin and tubulin, as well as cell cycle regulators and disease-related proteins such as huntingtin. Unlike GroEL, TRIC operates without a co-chaperone "lid" structure, relying instead on subunit heterogeneity and conformational changes to encapsulate substrates within its central cavity. Its role in maintaining protein quality control links it to neurodegenerative diseases (e.g., Alzheimer’s, Parkinson’s) and cancer, where misfolded proteins accumulate or oncoproteins depend on TRIC for stability.
Recombinant TRIC proteins are engineered to study its mechanism or exploit its therapeutic potential. Producing functional TRIC in vitro is challenging due to its multi-subunit architecture. Current strategies involve co-expression systems in bacteria, yeast, or insect cells, often requiring optimized conditions to assemble active complexes. Recombinant TRIC variants are used to investigate substrate interactions, ATPase activity, and allosteric regulation. Additionally, TRIC-inspired synthetic chaperones are being explored to enhance yields of difficult-to-fold recombinant proteins in biomanufacturing. Recent cryo-EM studies of recombinant TRIC have unveiled dynamic folding cycles, offering insights for designing small-molecule modulators targeting chaperonin dysfunction in diseases.
