Figure 2

Human A2M alpha-2-macroglobulin (GeneID 2) and its orthologs from 9 species. Reference species are marked with *. Each of these genes encodes a single RefSeq protein. This schematic shows the sequence alignment. Protein-coding regions were mapped to sequence with vertical green lines showing splice boundaries (7 proteins have 36 coding exons; others are truncated or extended). In reality, splice boundaries will not all align perfectly. Annotations predicted from sequence include signal peptide and five distinct CDD superfamilies.
