Protein attributes

Sequence length	564 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

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. Expressed in rods and cones cells. Ref.2
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. 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.
