Notes:
(+) A plus sign indicates additional positions described in [1].
(1) The amino acids at positions 1.2 and 1.1 for HLA-DRA were identified by amino acid sequencing [2] and extrapolated for the G-ALPHA [D1] domains of the other MH2-a chains and for the MH2-b HLA-DQA and H2-DQA chains. These additional amino acids, and those at positions 1.10-1.1 of the G-ALPHA [D1] domain of the HLA-DMA and H2-DMA chains, need to be confirmed experimentally in the mature chain. This also concerns positions 1.3-1.1 of the G-ALPHA1-LIKE [D1] domain of the Mus musculus CD1D1 and positions 1.1 of Mus musculus FCGRT.
