General annotation (Comments)

Function

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.

Catalytic activity

ATP + [rhodopsin] = ADP + [rhodopsin] phosphate.

Subcellular location

Membrane; Lipid-anchor.

Tissue specificity

Retinal-specific. Primarily located in rod outer segments. Expressed also in cones cells. Ref.2 Ref.3

Post-translational modification

Autophosphorylated, Ser-21 is a minor site of autophosphorylation compared to Ser-491 and Thr-492 By similarity. Phosphorylation at Ser-21 is regulated by light and activated by cAMP By similarity. Ref.3

Farnesylation is required for full activity By similarity.

Sequence similarities

Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. GPRK subfamily.

Contains 1 AGC-kinase C-terminal domain.

Contains 1 protein kinase domain.

Contains 1 RGS domain.
