Two visual pigment opsins, one expressed in the dorsal region and another in the dorsal and ventral regions, of the compound eye of a dragonfly, Sympetrum frequens Two visual pigment opsins, one expressed in the dorsal region and another in the dorsal and ventral regions, of the compound eye of a dragonfly, Sympetrum frequens 蟻川, 謙太郎 ARIKAWA, Kentaro OZAKI, Koichi TSUDA, Takanari KITAMOTO, Junko MISHINA, Yuji This paper describes the primary structure of two visual pigment opsins (DfRh1 and DfRh2) in the regionalized compound eye of a dragonfly,Sympetrum frequens. The amino acid sequences were deduced from the nucleotide sequences of cDNAs isolated from a cDNA library of the dragonfly retina. The two opsins both consist of 379 amino acids with 81.3% identity. Analysis of hydropathy indicated that the sequences have seven transmembrane domains like those of previously described opsins. Expression analysis using RT-PCR revealed that DfRh1 was present only in the dorsal region whereas DfRh2 was detected in both the dorsal and the ventral regions of the eye. journal article SpringerLink 1995-06 Invertebrate Neuroscience 1 1 33 39 Invertebrate Neuroscience 13542516 https://ir.soken.ac.jp/records/3607 eng 10.1007/BF02331830 http://doi.org/10.1007/BF02331830 SpringerLink(The original publication is available at www.springerlink.com) metadata only access
