Grm2 Gene Summary [Mouse]

Enables calcium channel regulator activity and group II metabotropic glutamate receptor activity. Involved in presynaptic modulation of chemical synaptic transmission. Acts upstream of or within gene expression; intracellular glutamate homeostasis; and long-term synaptic depression. Located in neuron projection. Is active in glutamatergic synapse and postsynaptic membrane. Is expressed in brain; cerebellum internal granule cell layer; and telencephalon. Orthologous to human GRM2 (glutamate metabotropic receptor 2). [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 Grm2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
