Taar4

Gene
Taar4
Protein
Trace amine-associated receptor 4
Organism
Mus musculus
Length
347 amino acids
Function
Olfactory receptor specific for 2-phenylethylamine, a trace amine present at high concentration in the urine of carnivore species, playing a key role in fear and avoidance responses. 2-phenylethylamine acts as a kairomone in the chemical detection of carnivore odor and triggers fear in mice. This receptor is probably mediated by the G(s)-class of G-proteins which activate adenylate cyclase.
Similarity
Belongs to the G-protein coupled receptor 1 family.
