Grk3 Gene Summary [Rat]
Enables D1 dopamine receptor binding activity; G protein-coupled receptor kinase activity; and beta-adrenergic receptor kinase activity. Involved in several processes, including desensitization of G protein-coupled receptor signaling pathway; inositol phosphate metabolic process; and rhodopsin metabolic process. Located in several cellular components, including Z disc; dendrite; and sperm midpiece. Is active in glutamatergic synapse; postsynaptic density; and presynapse. Biomarker of Parkinson's disease; hypertension; and hypothyroidism. Orthologous to human GRK3 (G protein-coupled receptor kinase 3). [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 Grk3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
