Phylogenetic tree of human and fish sodium/potassium/chloride co-transporter proteins (NKCC). Maximum likelihood tree with 100 bootstraps of round goby (Neogobius melanostomus, orange), zebrafish (Danio rerio), threespine stickleback (Gasterosteus aculeatus), nile tilapia (Oreochromis niloticus), blue-spotted mudskipper (Boleophthalmus pectinirostris), and as non-fish representative human (Homo sapiens, gray). Gobiidae feature more NKCC2 genes (gray box). Potassium/chloride co-transporters (KCC) indicated in gray type and with gray lines on top are used as outgroup
