The three-dimensional structure mapping of the amino acid sequence in the antigen binding domain of the HLA-A molecule. The amino acid sequence was mapped onto its molecular surface. Amino acid variability at position 62 (an important T cell receptor contact site) and 163 (a peptide and a T cell receptor contact site) were found to be associated with increased risk of delayed allograft function.
