Structural highlights
Function[HA1B_MOUSE] Involved in the presentation of foreign antigens to the immune system. [B2MG_MOUSE] Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe 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.
