Fig. 2. Phylogenic kinship of trout gastrin-like EST (A) and trout ATP4A-like EST
(B) to those of other species. Based on the translated amino acid sequence,
trout gastrin-like EST has 64% homology with halibut gastrin, and trout
ATP4A-like EST is 98% homologous to flounder ATP4A. Gastrin and CCK belong to
the same peptide family, but the trout gastrin-like EST belongs to a gastrin
cluster that is sufficiently removed from the trout CCK cluster (not shown).
Gas, gastrin; CCK: cholecystokinin; ATP4A: H+/K+-ATPase;
ATP1A: Na+/K+-ATPase. Trout EST1 (gi:42752688) and trout
EST2 (gi:42817423) in B are 97% homologous to one another in nucleotide base
sequence.
