Figure 2

Amino acid alignment of guppy LWS opsins with a sample of fish LWS opsins. Human red and green LWS opsins, and bovine (RH1) rhodopsin, are also included for reference. Numbering corresponds to human LWS opsins. Structural elements (transmembrane domains (TM), and extracellular (E) and cytoplasmic (C) loops) are indicated beneath the alignment. Sites variable among guppy LWS opsins are marked with an asterisk. Genbank accession numbers for the LWS sequences used to create the alignment: Lucania goodei LWSA (AY296740), Lucania goodei LWSB (AY296741), Oryzias latipes LWSB (AB223052), Oryzias latipes LWSA (AB223051), Dimidiochromis compressiceps (AF247131), Oreochromis niloticus (AF247128), Tetraodon nigroviridis (AY598943), Takifugu rubripes (AY598942), Salmo salar (AY214131), Plecoglossus altivelis (AB107771), Danio rerio LWS2 (AB087804).
