Fig. 1. Phylogenetic analysis of Na+/K+-ATPase
-isoform amino acid sequences. Numbers presented at each branch point
represent bootstrap values from 500 replicates. Bold-face type indicates
Na+/K+-ATPase
-isoforms identified in the present
study and each is named according to its position in the phylogenetic tree.
Fruitfly Na+/K+-ATPase was used as an outgroup.
