Fig. 3From: Diversification of non-visual photopigment parapinopsin in spectral sensitivity for diverse pineal functionsUV-sensitive and blue-sensitive parapinopsins. Absorption spectra in the dark (black) and after light-irradiation (gray) for a zebrafish PP1, b pufferfish PP1, c spotted gar parapinopsin, d zebrafish PP2, e pufferfish PP2, and f rainbow trout PP2. Note that the absorption spectrum of zebrafish PP2 after light-irradiation (gray) was calculated based on the spectral change measured using pre-purified samples (Additional file 3: Figure S3) and the rainbow trout PP1 was not successfully expressed in cultured cellsBack to article page
