Fig. 1. (A) Pufferfish FXYD (pFXYD) nucleotide sequence and deduced amino acid sequence. The transmembrane domain is shaded gray; the predicted signal peptide is underlined; the circle indicates the site for phosphorylation; the boxes indicate the highly similar FXYD motif and two glycine residues (G39 and G50). (B) Phylogenetic tree of pFXYD with known human FXYD members and related EST sequences from various teleost fish. Accession numbers are: shark PLMS, CAD88978; human FXYD1, NP_005022; human FXYD2.a, NP_001671; human FXYD2.b, NP_067614; human FXYD3, NP_005962; human FXYD4, NP_775183; human FXYD5, NP_054883; human FXYD6, NP_071286; human FXYD7, NP_071289; zebrafish EST-FXYD6, AW153757; zebrafish EST-FXYD8, AI958251; zebrafish EST-FXYD9, AW455046; medaka EST-FXYD.a, AU169681; medaka EST-FXYD.b, AU169966; Fugu EST-FXYDa, CA332188; Xenopus FXYD1, NP_001011320.
