  • G-protein coupled receptor activity
  • glutamate receptor activity
Processes
  • negative regulation of cAMP biosynthetic process
  • sensory perception of smell
  • adenylate cyclase-inhibiting G-protein coupled glutamate receptor signaling pathway
  • visual perception

General FunctionGroup iii metabotropic glutamate receptor activity
Specific FunctionG-protein coupled receptor for glutamate. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Signaling inhibits adenylate cyclase activity.
