Ligand Sp. Action Value Parameter Reference
isoamylamine Small molecule or natural product Ligand is endogenous in the given species Ligand has a PDB structure Mm Full agonist 5.0 pEC50 2
⤷ pEC50 5.0 (EC50 1x10-5 M) [2]
Agonist Comments
Cyclohexylamine has been shown to be an agonist at this receptor in mice [2]. It has been shown that the agonists of murine TAAR3 do not activate intact primate and mammalian orthologs [3].
