abstract：:There have been several attempts over the years to identify positions in the peptide-binding region (PBR) of human leukocyte antigens (HLA) that influence the specificity of bound amino acids (AAs) at each position in the peptide. Originally, six pockets (A-F) were defined by calculating the surface area of the PBR on...
