ⓘ Metabotropic glutamate receptor 4

Metabotropic glutamate receptor 4 is a protein that in humans is encoded by the GRM4 gene.

Together with GRM6, GRM7 and GRM8 it belongs to group III metabotropic glutamate receptor family. Group III receptors are linked to inhibition of camp cascade. Activation of GRM4 has potential therapeutic benefits in the treatment of Parkinsons disease. A splice variant of the "taste-GRM4" involved in the perception of umami.
