Grm2 Gene Summary [Rat]
Enables group II metabotropic glutamate receptor activity and scaffold protein binding activity. Involved in several processes, including behavioral response to nicotine; positive regulation of phosphatidylinositol 3-kinase/protein kinase B signal transduction; and regulation of amine transport. Located in astrocyte projection and axon. Is active in presynaptic membrane. Used to study heroin dependence. Biomarker of schizophrenia. 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 rat 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.
