MURINE CD8AA ECTODOMAIN FRAGMENT IN COMPLEX WITH H-2KB/VSV8
OverviewOverview
The crystal structure of the two immunoglobulin variable-like domains of, the murine CD8alphaalpha homodimer complexed to the class I MHC H-2Kb, molecule at 2.8 A resolution shows that CD8alphaalpha binds to the, protruding MHC alpha3 domain loop in an antibody-like manner. Comparison, of mouse CD8alphaalpha/H-2Kb and human CD8alphaalpha/HLA-A2 complexes, reveals shared as well as species-specific recognition features. In both, species, coreceptor function apparently involves the participation of CD8, dimer in a bidentate attachment to an MHC class I molecule in conjunction, with a T cell receptor without discernable conformational alteration of, the peptide or MHC antigen-presenting platform.
