Molecular Characterization of MHC Class I Genes in Four Species of the Turdidae Family to Assess Genetic Diversity and Selection

Figure 3

Alignment of deduced amino acid sequences of all alleles retrieved from four species of the Turdidae family. Dots (.) indicate identity with the reference sequence. Light gray color represents codons presumably coding for peptide binding regions upon alignment with human and other avian species. The light brown region indicates flanking introns. - indicates missing nucleotides. represents codons positively selected in almost all of the tests performed for selection analysis. ! indicates the homologue region also positively selected in most of avian species. # inferred homology with human.
