Comparison of the deduced amino acid sequences of three putative goldfish olfactory receptors with the sequences of their closest homologs (CF and ZF denote catfish and zebrafish, respectively). In this and subsequent comparisons, identical residues are shaded. The predicted positions of the seven transmembrane domains are boxed. Dots indicate gaps that were inserted for optimal alignment. (A) GFA2. (B) GFA25. (C) GFA28.
