Retina-specific kinase involved in the signal turnoff via phosphorylation of rhodopsin (RHO), the G protein- coupled receptor that initiates the phototransduction cascade . This rapid desensitization is essential for scotopic vision and permits rapid adaptation to changes in illumination (By similarity). May play a role in the maintenance of the outer nuclear layer in the retina (By similarity).
Subcellular locations: Membrane, Cell projection, Cilium, Photoreceptor outer segment
Subcellular location is not affected by light or dark conditions.
Retinal-specific. Expressed in rods and cones cells.
