The peptide-loading complex is a bottleneck in antigen presentation by major histocompatibility complex (MHC) class I molecules. While the structures of its individual components were known, the recent report of the 7.2 Å structure of the entire complex now fits them into their functional context, explaining this monumental step in antigen acquisition by MHC class I molecules.
