    Abstract

    The polymerase chain reaction was used to isolate clones with class I major histocompatibility complex sequences from fish (carp), amphibian (axolotl), and two species of reptile (lizard and snake). The lizard and snake clones were used to isolate class I cDNA clones. All the sequences showed the expected evolutionary relatedness. The carp and axolotl clones and one lizard cDNA clone lacked the first cysteine in the alpha 3 domain which in other class I heavy chains forms an intradomain disulfide bond. A small number of amino acid residues are conserved in the class I heavy chain sequences from all five classes of vertebrates. In the first two domains they are symmetrically clustered and contribute to intra- and interdomain contacts. None of these invariant residues are at peptide-binding, T-cell receptor-interacting, or CD8-binding positions.
