The TCP1 Ring Complex (TRiC) is a protein complex found in eukaryotic cells that assists in the proper folding of newly synthesized proteins. It is composed of eight identical subunits, forming a cylindrical structure that provides a controlled environment for proteins to achieve their functional shapes. TRiC is particularly important for the folding of large and complex proteins, including some involved in cellular processes. TRiC is part of the larger family of chaperonin proteins, which help prevent misfolding and aggregation of proteins. It works in conjunction with other chaperones, such as Hsp60, to ensure that proteins are correctly folded before they become active. Proper protein folding is crucial for maintaining cellular health and function.
