The K(bm1) and K(bm8) natural mutants of the murine MHC class I molecule H-2K(b) were originally identified by allograft rejection. They also bind viral peptides VSV8 and SEV9 with high affinity, but their peptide complexes have substantially decreased thermostability, and the K(bm1) complexes do not elicit alloreactive T cell responses ...
