The deduced amino acid sequences of coelacanth RH1 (RH1Lc), coelacanth RH2 (RH2Lc), and coelacanth ψB (ψBLc). Gaps, denoted by dots, were inserted in the sequences for the optimal alignment. Deletion, insertion, and nonsense nucleotide mutations in ψsws1Lc are noted by lower case letters. ∗ indicates a stop codon. Exon 5 of ψsws1Lc is missing. Putative transmembrane domains I–VII are indicated by horizontal lines.
