Figure 2.

Phylogenetic tree of functional EAR genes of rodents. After the removal of gaps, a total of 390 nucleotide sites are used in tree-making. Bootstrap percentages that are equal to or higher than 70 are shown on interior branches. Following convention (14–16), house mouse genes are designated either by mEAR or mR, whereas rat genes are designated by rR. The pI values, as well as the numbers of arginine and lysine residues in the mature proteins are shown to the right of the tree. Genes from different species are depicted with different colors.
