Opsin, blue sensitive (IPR001521)

Short name: Opsin_blue

Overlapping homologous superfamilies


Family relationships


Opsins are the photoreceptors of animal retinas: 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. Blue-sensitive opsin has an absorption maximum at 420nm. The ratio of blue cones to rods is ~1:200. Deficiency in blue opsin results in tritanopia colour blindness.
