Rhodopsin kinase (EC, cone opsin kinase, G-protein-coupled receptor kinase 1, GPCR kinase 1, GRK1, GRK7, opsin kinase, opsin kinase (phosphorylating), rhodopsin kinase (phosphorylating), RK, STK14) is a serine/threonine-specific protein kinase involved in phototransduction.[1][2][3][4][5][6][7][8] This enzyme catalyses the following chemical reaction

ATP + rhodopsin <math>\rightleftharpoons</math> ADP + phosphorhodopsin

Mutations in rhodopsin kinase are associated with a form of night blindness called Oguchi disease.[9]
