Sequence comparison between antigen presenting genes in the MHC IA and IB regions in Atlantic salmon and rainbow trout
| GENE | % nt Sasa IA/IB | % aa Sasa IA/IB | % nt IA Sasa/Onmy | % aa IA Sasa/Onmy | % nt IB Sasa/Onmy | % aa IB Sasa/Onmy |
| PSMB8 | 95 | 95 | - | 98 | 96 | 98 |
| PSMB10 | 94 | 92 | 94 | 92 | 97 | 98 |

| TAP2 | 92 | 90 | 94 | 93 | 96 | 95 |
The table shows comparison of % nucleotide (nt) and % amino acid (aa) identity between the genes found respectively in the Atlantic salmon IA vs IB region and in the IA and IB region of Atlantic salmon versus rainbow trout [6].
