Automated description from the Alliance of Genome Resources (Release 7.0.0)
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. Is expressed in brain and cerebellum internal granule cell layer. Orthologous to human GRM2 (glutamate metabotropic receptor 2).
