To investigate the molecular basis of the interaction between the T cell receptor and the MHC class I antigen in an allogeneic response, a soluble counterpart of the murine class I molecule, H-2Kb, was genetically engineered. Cells secreting this soluble molecule, H-2Kb/Q10b, inhibited stimulation of an H-2Kb-reactive T cell hybridoma by cells transfected with H-2Kbm10, a weak stimulus, but not by H-2Kb- or H-2Kbm6-transfected cells. Soluble purified H-2Kb/Q10b protein also blocked T cell stimulation. In addition, a peptide from the wild-type H-2Kb molecule spanning the region of the bm10 mutation specifically inhibited activation of the T cell hybridoma by H-2Kbm10 cells, thus suggesting that amino acid residues 163-174 of H-2Kb define a region important for T cell receptor binding. An estimate for the Kd of the T cell receptor for soluble H-2Kb/Q10b was 10(-7) M, while the Kd for soluble peptide 163-174 was 10(-4) M.
