Retinalni G protein spregnuti receptor je protein koji je kod čoveka kodiran RGR genom.^[1]^[2]

{{PBB_Summary | section_title = | summary_text = Defekti ovog gena su uzrok retinitis pigmentose. Oni mogu da se ispolje kao autosomalna recesivna ili dominantna retinitis pigmentosa (arRP i adRP, respektivno). Ovaj gen je član familije rodopsinu-sličnih receptora GPCR. Poput drugih opsina koji vezuju retinaldehid, on sadrži konzervirani lizin u svom sedmom transmembranskom domenu. Za ovaj protein se smatra da dejstvuje kao fotoizomeraza koja katalizuje konverziju sve-trans-retinala u 11-cis-retinal, slično retinohromu kod beskičmenjaka. Reverzna izomerizacija rodopsina se odvija u retinalnim fotoreceptorskim ćelijama. Ovaj protein je ekskluzivno izražen u tkivima koja su susedna retinalnim fotoreceptorskim ćelijama i retinalnom pigmentnom epitelu. Alternativno splajsovanje rezultuje u višestrukim transkriptnim varijantama koje kodiraju različite isoforme.^[2]
