title: Partial N-terminal amino acid sequence analyses and comparative tryptic peptide maps of murine Ia molecules encoded by the I-A subregion.
abstract: The partial N-terminal amino acid sequences and tryptic peptide maps of I-A subregion products from the H-2b, H-2d, H-2k and H-2s haplotypes demonstrate that haplotype-associated differences are present in both alpha and beta polypeptides. The genetic and evolutionary implications of these multiple amino acid substitutions and the homology relationships among Ia molecules from human, guinea pig and the I-E subregion of the mouse are discussed.
