Fig. 4. Deduced amino acid sequences of eel homologues of AQP1, S-AQP and L-AQP, in comparison to the sequence of mouse AQP1. Periods and hyphens indicate identical residues and gaps introduced for alignment, respectively. Two NPA motifs are shaded. Asterisks indicate differences between S-AQP and L-AQP. The antibody was raised against a synthetic peptide corresponding to the underlined sequence.
