Alignment of amino acid sequence of IFNα genes. Human IFNα2 and IFNα5 amino acid sequences were aligned with the marmoset and tamarin IFNα2 sequences. The human IFNα2 was used as the consensus sequence with sequence identity to this sequence indicated by a dot. The full length intact proteins are 189 amino acids (188 amino acids for human IFNα2, note internal deletion) with the first 23 amino acids being the cleaved signal sequence. The marmoset and tamarin IFNα2 genes differ at 10 residues.
