TRiC, or TCP1 Ring Complex, is a protein complex that plays a crucial role in the folding of other proteins within cells. It is part of the chaperonin family, which helps ensure that proteins achieve their proper three-dimensional structures, essential for their function. The TRiC complex is found in eukaryotic cells, including those of humans. It assists in the folding of a variety of proteins, particularly those that are large and complex. By preventing misfolding and aggregation, TRiC contributes to cellular health and proper functioning of biological processes.
