Amino acid sequence alignment and structure-based view of SMO isoforms. A) Amino acid sequence alignment of the regions corresponding to Nuclear Domain A (NDA) and B (NDB) of SMO long isoforms. For acronyms and isoform numbering see Table 2. B) Structure-based view of the amino acid sequence conservation in SMOs (left) and in the NDA of placental mammals as opposed to marsupials and monotremates (right). Protein regions coloured in blue correspond to residues conserved in at least 90% of the amino acid sequences analysed.
