Opsin red/green sensitive (IPR000378)

Short name: Opsin_red/grn

Overlapping homologous superfamilies


Family relationships


Opsins are the photoreceptors of animal retinas [PMID: 10349976]. Vertebrate rhodopsin is found in rod cells and mediates scotopic vision; red, green and blue opsins are found in cone cells and mediate photopic vision. Red-sensitive opsin has an absorption maximum at 560nm; its deficiency results in protanopia colour blindness [PMID: 1302020]. Green-sensitive opsin has an absorption maximum at 530nm; its deficiency results in deuteranopia colour blindness [PMID: 8185948, PMID: 9860863]. The ratio of green and red cones to rods is ~1:30.
