Detailed explanation-1: -The 1 and 2 domains form the peptide-binding site: this is a groove on the upper surface of the MHC class I molecule, which binds antigenic peptides of 8–10 amino acids in length.
Detailed explanation-2: -MHC class I or major histocompatibility complex type 1 is a diverse set of cell surface receptors expressed on all nucleated cells in the body, as well as platelets.
