Thr-68 and Ser-156 are conserved across species. Comparisons of conserved Thr-68 and Ser-156 residues in AIRE between species. Sequences from H. sapiens, P. troglodytes, M. mulatta, R. norvegicus, M. musculus, C. lupus, and Danio rerio are presented. The number of PEST residues surrounding Thr-68 and Ser-156 is indicated on the bottom. White to black bars indicate increased conservation of amino acids in these FBXO3 proteins.
