Grk1 Gene Summary [Rat]
Enables rhodopsin kinase activity. Involved in protein autophosphorylation; response to light stimulus; and response to xenobiotic stimulus. Predicted to be located in photoreceptor outer segment. Predicted to be active in cytoplasm. Used to study congestive heart failure. Biomarker of retinal disease. Human ortholog(s) of this gene implicated in Oguchi disease-2 and night blindness. Orthologous to human GRK1 (G protein-coupled receptor kinase 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Grk1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
