Fig. 1

Amino acid alignment of Gq-opsins from scallop (Air-OPNGq1-OPNGq4) and squid, Todarodes pacificus (Tpa-OPNGq1). The alpha-helix domains are based on protein structure homology modeling (this study) or have been adapted from Shimamura et al. [52]. Sequence motifs described in Table 2 are in blue; residues important for structural confirmation are in yellow. Numbering of amino acid positions begins with the start codon (Met) of Tpa-OPNGq1
