The crowns have eyes: Multiple opsins found in the eyes of the Crown-of-Thorns StarfishAcanthaster planciincluding the first r-opsin utilized by a deuterostome eye
Abstract:Opsins are G protein-coupled receptors used for both visual and non-visual photoreception, and these proteins evolutionarily date back to the base of the bilaterians. In the current sequencing age, phylogenomic analysis has proven to be a powerful tool, facilitating the increase in knowledge about diversity within the opsin subclasses and, so far, nine paralogs have been identified. Within echinoderms, opsins have been studied in Echinoidea and Ophiuroidea, which do not possess proper image forming eyes, but r… Show more
