Figure 9

The selected AA sequences from the alignment of 115 AA sequences to illustrate an exclusively conserved intron intervening site among the tunicate and vertebrate GIRK group. The yellow background and boxed regions illustrate exclusively conserved AA sites among the tunicate and vertebrate GIRK group and the suggested interaction sites with G-protein beta and gamma[35]. Intron-intervening sites are illustrated by changes in the colors of AA code characters. A red to black transition or vice versa represents phase 0 intron insertion. Green and sky blue indicate phase 1 intron and phase 2 intron insertions, respectively.
