text: A cDNA clone for a new metabotropic glutamate receptor, mGluR5, was isolated
through polymerase chain reaction-mediated DNA amplification by using primer sequences
conserved among the metabotropic glutamate receptor (mGluR) family and by the
subsequent screening of a rat brain cDNA library. The cloned receptor consists
of 1171 amino acid residues and exhibits a structural architecture common to the
mGluR family, possessing a large extracellular domain preceding the seven putative
membrane-spanning segments. mGluR5 shows the highest sequence similarity to mGluR1
among the mGluR members and is coupled to the stimulation of phosphatidylinositol
hydrolysis/ Ca2+ signal transduction in Chinese hamster ovary cells transfected
with the cloned cDNA. This receptor also resembles mGluR1 in its agonist selectivity
and antagonist responses; the potency rank order of agonists for mGluR5 was determined
to be quisqualate > L-glutamate ≥ ibotenate > trans-1-aminocyclopentane-1,3-dicarboxylate.
Blot and in situ hybridization analyses indicated that mGluR5 mRNA is widely distributed
in neuronal cells of the central nervous system and is expressed differently from
mGluR1 mRNA in many brain regions. This investigation thus demonstrates that there
is an additional mGluR subtype which closely resembles mGluR1 in its signal transduction
and pharmacological properties and is expressed in specialized neuronal cells
in the central nervous system.
