Figure 7From: Ancient intron insertion sites and palindromic genomic duplication evolutionally shapes an elementally functioning membrane protein familyAlignment of 7 tunicate, 6 Caenorhabditis , and 7 bacterial IRK AA sequences (continued from Figure 6.) The alignments for the rest parts of AA sequences, which are not included in Fig. 6 and 7, are illustrated in an additional file [see Additional file 6].Back to article page
