In the figures, gray-filled squares and red open squares indicate coding exons and introns, respectively, in the coding regions. indicates noncoding exons. and represent membrane-spanning and pore regions within the coding exons. The inserts in the respective figures represent expanded sequences of the regions containing the membrane-spanning and pore segments. Scales in the graphs are bp
