IMGT pMHC contact sites of human HLA-A*0201 MHC-I and a 9-amino acid peptide
(1ao7). (A) 3D structure of the human HLA-A*0201 groove. (B) IMGT pMHC contact sites
IMGT Colliers de Perles. Both views are from above the cleft with G-ALPHA1 on top and G-
ALPHA2 on bottom. In the box, C1 to C11 refer to contact sites (Kaas and Lefranc 2005). 1 to
9 refer to the numbering of the peptide amino acids P1 to P9. There are no C2 and C7 in
MHC-I 3D structures with 9-amino acid peptides. There is no C5 in this 3D structure as P4
does not contact MHC amino acids (4G is shown between parentheses in the box). (A color
version of this figure appears between pages 76 and 77.)
