Gene Group (FlyBase)
METABOTROPIC GLUTAMATE RECEPTORS -
Metabotropic glutamate receptors (mGluRs) are Class C GPCRs. They bind the neurotransmitter glutamate as an obligate homodimer. (Adapted from PMID:20055706 and FBrf0162280).
Protein Function (UniProtKB)
G-protein coupled receptor for glutamate. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors.
(UniProt, P91685)
Summary (Interactive Fly)
G-protein coupled receptor - modulates presynaptic excitability properties and synaptic architecture - acts in conjunction with FMRP to regulate presynaptic properties

Additional Descriptive Data
mGluR protein is strongly expressed in the ellipsoid body ring in the innervation regions of R3 and R4d ring neurons. In the fan-shaped body expression is detected in the central and ventral layers, in the bulb (lateral triangle) in the nodulus (stronger expression in the dorsal region layer III) and protocerebral bridge. Co-localisation with Scer\GAL4VGlut.PD is observed in the ellipsoid body rings R3 and R4d, in the fan-shaped body, nodulus and protocerebral bridge.
There are fourteen mGluR immunopositive cell bodies are found in the third instar larval brain. Expression of mGlu</up>RA is detected in the dorsal and ventral aspect of the adult fan-shaped body of the central complex. Three neurons of the metathoracic neuromere, and four pairs of neurons in the abdominal neuromere are mGluR immunopositive.

      Other Comments
      Fmr1 and mGluR convergently regulate presynaptic properties. At the protein level, Fmr1 is upregulated in mGluR mutants, and mGluR is upregulated in Fmr1 mutants. Null mGluR mutants display defects in coordinated movement behavior, which are rescued by removing Fmr1 expression. Null Fmr1 mutants display increased neuromuscular junction presynaptic structural complexity and elevated presynaptic vesicle pools, which are rescued by blocking mGluR signaling. Null Fmr1 brain neurons similarly display increased presynaptic architectural complexity, which is rescued by blocking mGluR signaling.
      When co-expressed in Xenopus oocytes with a mammalian G-protein coupled inwardly rectifying potassium channel protein the Glu-RA protein activates an inwardly rectifying potassium current.
      Encodes a G protein-coupled metabotropic glutamate receptor.
      Glu-RA is expressed in the adult and in the CNS of late embryos.
