Grm1 Gene Summary [Rat]

Enables nuclear estrogen receptor binding activity. Involved in calcium-mediated signaling; chemical synaptic transmission; and regulation of glutamatergic synaptic transmission. Located in several cellular components, including dendritic spine; neuronal cell body; and presynaptic membrane. Is active in glutamatergic synapse and postsynaptic density membrane. Biomarker of temporal lobe epilepsy. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 13 and spinocerebellar ataxia 44. Orthologous to human GRM1 (glutamate metabotropic receptor 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 Grm1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
