Structural studies on protein products of murine chromosome 17. III. Partial amino acid sequence of an H-2K(q) molecule

Twenty-one of the amino terminal twenty-seven amino acid residues have been assigned in the murine H-2K(q) molecule and several additional assignments and corrections have been made in both the H-2K(k) and H-2K(b) molecules. The study shows that H-2K(k) and H-K(q), which are serologically related, have an identical amino acid sequence for all twenty positions that can be compared, the H-2K(k) and H-2K(q) molecules differ from H-2K(b) at only two positions - 9 and 22, and the additional sequence data on the H-2K(k), -K(b), and -K(q) molecules increases the already striking homology between murine and human transplantation antigens.
