Associate Editor(s)-in-Chief: Henry A. Hoff

In the schematic representation the MHC class I consists of a single transmembrane polypeptide chain (the α-chain with three polymorphic domains, α1, α2, α3) and a β2 microglobulin.
Main article: MHC class I

MHC class I molecules are heterodimers, consisting of a single transmembrane polypeptide chain (the α-chain) and a β2 microglobulin (which is encoded elsewhere, not in the MHC). The α chain has three polymorphic domains, α1, α2, α3. Between α1 and α2 is the peptide-binding groove which binds peptides derived from cytosolic proteins. The groove consists of eight β-pleated sheets on the bottom and two α helices making up sides. The peptide in the groove remains bound for the life of the class I molecule, and is typically 8-9 amino acids in length.
