Additional file 3: Figure S2. of Evolutionary origin of type IV classical cadherins in arthropods

Alignment of the entire amino acid sequences of thirteen type III cadherins in arthropods, and comparison of the exon-intron organizations. The alignment was produced using the ClustalW algorithm without manual adjustment. The classical cadherins shown are Pt1-, Pt2-, Mma1-, Mma2-, Mo-, Sm2-, Cm-, Le2-, Ph2-, Ha2-, Ea2-, Dp2-, and DN-cadherins. The domain organization is indicated above the Pt1-cadherin sequence. Blue lines with breakages indicate exons, and the breaking points indicate intron insertion sites revealed by comparisons with the corresponding genomic sequences. (PDF 5991Â kb
