Grk3 Gene Summary [Mouse]
Enables G protein-coupled receptor kinase activity. Predicted to be involved in several processes, including desensitization of G protein-coupled receptor signaling pathway; inositol phosphate metabolic process; and rhodopsin metabolic process. Predicted to be located in several cellular components, including Z disc; dendrite; and sperm midpiece. Predicted to be active in glutamatergic synapse; postsynaptic density; and presynapse. Is expressed in several structures, including adrenal gland; gut gland; nervous system; submandibular gland primordium; and thymus primordium. 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 mouse 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.
