Eigenschaften

Bearbeiten

Der metabotrope Glutamatrezeptor 3 ist ein G-Protein-gekoppelter Rezeptor.[1] Er wird in größeren Mengen in der Großhirnrinde, im Thalamus, Subthalamus, in der Substantia nigra, im Hypothalamus, Hippocampus, Corpus callosum und in der Amygdala gebildet.[1] Gemeinsam mit mGluR2 bildet er die Gruppe II der metabotropen Glutamatrezeptoren. Nach Bindung von Glutamat erfolgt eine Konformationsänderung, die eine Signaltransduktion über G-Proteine (aus der Familie Gi) bewirkt. In Folge wird die Adenylylcyclase gehemmt.[1] Der metabotrope Glutamatrezeptor 3 besitzt Disulfidbrücken und ist glykosyliert.[1]
