Metabotropic glutamate receptor 4 is a protein that in humans is encoded by the GRM4gene.[1][2][3]
Together with GRM6, GRM7 and GRM8 it belongs to group III of the metabotropic glutamate receptor family. Group III receptors are linked to the inhibition of the cyclic AMP cascade.[3]
Activation of GRM4 has potential therapeutic benefits in the treatment of parkinson's disease. Splice variant "taste-GRM4" is involved in the perception of umami taste.[4]
