Fig. 1.
Sequences of the C termini of the human, murine, and rat α-subunit. Amino acid residue numbers at the beginning and end of each sequence are indicated. Residues 663 (T/A), C664, and G667 in the human α-subunit are indicated. A692 in the murine and rat α-epithelial sodium channel (ENaC) corresponds to 663 in the human α-subunit. A696 in murine and rat α-ENaC correspond to G667 in the human α-subunit. G658 and G668 mark the beginning and end of the scanned residues in the human α-subunit.
