Entrez Gene summary for GRM1:
L-glutamate is the major excitatory neurotransmitter in the central nervous system and activates both ionotropic and
metabotropic glutamate receptors. Glutamatergic neurotransmission is involved in most aspects of normal brain function
and can be perturbed in many neuropathologic conditions. The metabotropic glutamate receptors are a family of G
protein-coupled receptors, that have been divided into 3 groups on the basis of sequence homology, putative signal
transduction mechanisms, and pharmacologic properties. Group I includes GRM1 and GRM5 and these receptors have been
shown to activate phospholipase C. Group II includes GRM2 and GRM3 while Group III includes GRM4, GRM6, GRM7 and GRM8.
Group II and III receptors are linked to the inhibition of the cyclic AMP cascade but differ in their agonist
selectivities. The canonical alpha isoform of the metabotropic glutamate receptor 1 gene is a disulfide-linked
homodimer whose activity is mediated by a G-protein-coupled phosphatidylinositol-calcium second messenger system.
Alternative splicing results in multiple transcript variants encoding distinct isoforms; some of which may have
distinct functions. (provided by RefSeq, Jul 2008)

UniProtKB/Swiss-Prot: GRM1_HUMAN, Q13255
Function: Receptor for glutamate. The activity of this receptor is mediated by a G-protein that activates a
phosphatidylinositol-calcium second messenger system. May participate in the central action of glutamate in the CNS,
such as long-term potentiation in the hippocampus and long-term depression in the cerebellum

summary for GRM1:
Metabotropic glutamate (mGlu) group I receptors are members of the metabotropic class of glutamate
receptors, which also includes mGlu group II and mGlu group III receptors. mGlu group I receptors are
divided into two subtypes, mGlu1 and mGlu5. The receptors are coupled to Gq/11 which activates phospholipase
C and they are also associated with Na+ and K+ channels. Their action is generally excitatory, increasing
conductance, causing more glutamate to be released from the presynaptic cell. They can also increase
inhibitory postsynaptic potentials (IPSPs), inhibit glutamate release and can modulate voltage-dependent
calcium channels. Group I mGluRs, unlike other groups, are activated by 3,5-dihydroxyphenylglycine (DHPG),
allowing their function to be isolated. The human genes for mGlu1 and mGlu5 receptors have been localized to
chromosomes 6 (6q24) and 11 (11q14.3) respectively.

  • Defects in GRM1 are the cause of spinocerebellar ataxia, autosomal recessive, 13 (SCAR13) [MIM:614831].
  • Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show
    progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration
    of the cerebellum with variable involvement of the brainstem and spinal cord. SCAR13 is characterized by delayed
    psychomotor development beginning in infancy. Affected individuals show mild to profound mental retardation with poor
    or absent speech as well as gait and stance ataxia and hyperreflexia
