1G7P - PubMed Abstract:
The crystal structure of a non-standard peptide, YEA9, in complex with H-2Kb, at 1.5 A resolution demonstrates how YEA9 peptide can bind with surprisingly high affinity through insertion of alternative, long, non-canonical anchors into the B and E pockets. The use of "alternative pockets" represents a new mode of high affinity peptide binding, that should be considered when predicting peptide epitopes for MHC class I. These novel interactions encountered in this non-canonical high affinity peptide-MHC complex should help predict additional binding peptides from primary protein sequences and aid in the design of alternative approaches for peptide-based vaccines.
