Given the structural similarities, it is believed that all these MHC I or MHC I-like molecules have evolutionary lineage with a common ancestor.[sup][13] The MHC locus has been found in all jawed vertebrates, however, the proto-MHC could trace back to the cephalochordate (amphioxus) and jawless vertebrate lineages.[sup][110],[111],[112] MHC II genes were firstly derived from proto-MHC by exon shuffling, combining an Ig-like C domain with a peptide binding region.[sup][113] Subsequently, another peptide binding region exon was added to MHC II [sz] chain to form the MHC I heavy chain, which happened at approximately 500 million years ago.
