CLASS II MHC I-AD IN COMPLEX WITH OVALBUMIN PEPTIDE 323-339CLASS II MHC I-AD IN COMPLEX WITH OVALBUMIN PEPTIDE 323-339
Structural highlights
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 PubMedWe have determined the structures of I-Ad covalently linked to an ovalbumin peptide (OVA323-339) and to an influenza virus hemagglutinin peptide (HA126-138). The floor of the peptide-binding groove contains an unusual beta bulge, not seen in I-E and DR structures, that affects numerous interactions between the alpha and beta chains and bound peptide. Unlike other MHC-peptide complexes, the peptides do not insert any large anchor residues into the binding pockets of the shallow I-Ad binding groove. The previously identified six-residue "core" binding motif of I-Ad occupies only the P4 to P9 pockets, implying that specificity of T cell receptor recognition of I-Ad-peptide complexes can be accomplished by peptides that only partially fill the MHC groove. Crystal structures of two I-Ad-peptide complexes reveal that high affinity can be achieved without large anchor residues.,Scott CA, Peterson PA, Teyton L, Wilson IA Immunity. 1998 Mar;8(3):319-29.
