WebThe visual pigment rhodopsin consists of 11-cis-retinal and opsin, the apoprotein of the pigment.Photon absorption causes bleaching of rhodopsin, a process that is initiated by the photoconversion of 11-cis-retinal to all-trans-retinal.Subsequently, rhodopsin undergoes a series of dark reactions that culminate in the dissociation of retinal, thus completing the … WebMay 16, 2013 · Jiang et al. (1993) identified an opsin-related gene that is preferentially expressed at high levels in the RPE and Muller cells of the neural retina. The gene encodes a putative RPE-retinal G protein-coupled receptor (RGR) with 7 transmembrane segments. The putative receptor most closely resembled the subfamily of visual pigments and ...
