THE HUMAN NON-CLASSICAL MAJOR HISTOCOMPATIBILITY COMPLEX MOLECULE HLA-E
Contents |
Overview
The crystal structure of the nonclassical human class lb MHC molecule, HLA-E has been determined in complex with a prototypic ligand, the nonamer, peptide (VMAPRTVLL), derived from the highly conserved residues 3-11 of, the human MHC class la leader sequence. The mode of peptide binding, retains some of the standard features observed in MHC class la complexes, but novel features imply that HLA-E has evolved to mediate specific, binding to a tightly defined set of almost identical hydrophobic peptides, from the highly conserved class l leader sequences. These molecular, adaptations make HLA-E a rigorous checkpoint at the cell surface reporting, on the integrity of the antigen processing pathway to CD94/NKG2, receptor-bearing natural killer cells.
Disease
Known disease associated with this structure: Hypoproteinemia, hypercatabolic OMIM:[109700]
