text: 'The metabotropic glutamate receptors are coupled to intracellular signal
transduction via G-proteins and consist of a family of at least five different
subtypes, termed mGluR1-mGluR5. We studied the signal transduction mechanism and
pharmacological characteristics of the rat mGluR3 and mGluR4 subtypes in Chinese
hamster ovary cells permanently expressing the cloned receptors. Both mGluR3 and
mGluR4 inhibit the forskolin-stimulated accumulation of intracellular cAMP formation
in response to agonist interaction. Consistent with the high degree of sequence
similarity to mGluR2, mGluR3 closely resembles mGluR2 in its agonist selectivity;
the potency rank order of agonists is L-glutamate > trans-1-aminocyclopentane-
1,3-dicarboxylate > ibotenate > quisqualate. mGluR4 is totally different
in its agonist specificity from any other member of the metabotropic receptors.
This receptor potently reacts with L-2-amino-4-phosphonobutyrate(L-AP4) in a stereo-selective
manner and moderately responds to L-serine-O-phosphate. mGluR4 thus corresponds
well to the putative L-AP4 receptor characterized from brain preparations. Blot
and in situ hybridization analyses indicated that both mRNAs are widely distributed
in the rat brain. mGluR3 mRNA is highly expressed in neuronal cells of the cerebral
cortex and the caudate- putamen, and in granule cells of the hippocampal dentate
gyrus. The expression pattern of mGluR4 mRNA is more restricted, and this expression
is prominent in the cerebellum, olfactory bulb, and thalamus. Furthermore, the
mGluR3 mRNA, unlike the other mRNAs for the metabotropic receptors, is highly
expressed in glial cells throughout the brain regions. The metabotropic glutamate
receptor subtypes can thus be classified into three subgroups according to the
similarity in their amino acid sequences, signal transduction, and agonist selectivity:
mGluR1/mGluR5, mGluR2/mGluR3, and mGluR4. The mRNAs for the individual receptor
subtypes, however, show overlapping but distinct patterns of expression in the
rat CNS.'
