A Comparative Genomic and Phylogenetic Analysis of the Origin and Evolution of the CCN Gene Family

Figure 4

Schematic diagram of the exon organization of CCN2 in representative species. Species names were listed on the left. In the diagram each box stands for an exon, and the number inside the box represents the base-pairs number of each exon. Exon organization was then aligned with the domains of the corresponding sequence.
