Metabotropni glutamatni receptor 8 je protein koji je kod ljudi kodiran GRM8 genom.^[1]^[2]

Funkcija уреди

Aminokiselina L-glutamat je glavni ekscitatorni neurotransmiter u centralnom nervnom sistemu koji aktivira jonotropne i metabotropne glutamatne receptore. Glutamatergična neurotransmisija učestvuje u većini aspekata normalnih moždanih funkcija. Ona može da bude poremećena u mnogim neuropatološkim oboljenjima. Metabotropni glutamatni receptori su familija G protein spregnutih receptora, koja se deli u tri grupe na osnovu homologije sekvence, mehanizma prenosa signala, i farmakoloških svojstava. Grupa I obuhvata GRM1 i GRM5. Ovi receptori aktiviraju fosfolipazu C. Grupa II obuhvata GRM2 i GRM3, dok su u grupi III GRM4, GRM6, GRM7, i GRM8. Receptori grupe II i III su vezani za inhibiciju kaskade cikličnog AMP-a ali se razlikuju u njihovim selektivnostima za agoniste. Alternativne splajsne varijante GRM8 su poznate, ali njihova svojstava nisu potpuno određena.^[2]
