FIG. 2.
Comparison of the nucleotide and amino acid sequences of Mx2 proteins of BALB/c and wild-type strains NJL and SPR. The inserted A residue at position 1367 is found in Mx2 mRNA of BALB/c where the two long ORFs overlap. The Mx2 mRNA of the wild-type strains contained a single long ORF, as the A was excluded.
