Rhodopsin kinase (EC 2.7.11.14, rod opsin kinase, G-protein-coupled receptor kinase 1, GPCR kinase 1, GRK1, opsin kinase, opsin kinase (phosphorylating), rhodopsin kinase (phosphorylating), RK, STK14) is a serine/threonine-specific protein kinase involved in phototransduction. This enzyme catalyses the following chemical reaction:

ATP + rhodopsin ADP + phospho-rhodopsin

Mutations in rhodopsin kinase are associated with a form of night blindness called Oguchi disease.
