Monoamine receptor

A monoamine receptor is a receptor for the monoamine neurotransmitters and/or trace amines, endogenous small-molecule signaling molecules with a monoamine structure. The monoamine receptors are almost all G protein-coupled receptors, with the serotonin 5-HT₃ receptor being a notable exception as a ligand-gated ion channel. Monoamine receptors are the biological targets of many drugs; such drugs may be referred to as "monoaminergic".

List of receptors

Monoamine receptors include the following classes:

Adrenergic receptors – bound by epinephrine and norepinephrine
Dopamine receptors – bound by dopamine
Histamine receptors – bound by histamine
Melatonin receptors – bound by melatonin
Serotonin receptors – bound by serotonin
Trace amine-associated receptors – bound by trace amines, thyronamines, monoamine neurotransmitters, and trimethylamine
