Fig. 2. Identity of RH1 opsins. (A) Alignment of RH1A and RH1B amino acid
sequences. The deleted residues in RH1B that are involved in phosphorylation
are indicated by arrowheads. (B) Alignment of 5' upstream region of RH1A
and RH1B. The putative TATA boxes and start codons are underlined. (C)
Phylogenetic tree of RH1 opsin nucleotide sequences generated by the
neighbour-joining method. The RH2 sequences from Carassius auratus
and extra-retinal sequences from Takifugu rubripes and Salmo
salar were used as outgroups. All sequences were aligned with ClustalV.
GenBank accession numbers for the sequences (in order from the top of the
tree) are as follows: AJ249203, AJ249202, U12328, Y18677, L11863, S74449,
AF105152, EF517407, EF517408, AY141256, AF201470, Y18666, AB185235, AB180742,
NM_001078631, EF517404, EF517405, L11865, AF201469, NM_001033849.
