SUBCELLULAR LOCALIZATION

plasma membrane

basic FUNCTION	may be mediated by the G(s)-class of G-proteins which activate adenylate cyclase
	regulator of dopaminergic neurotransmission
	tonically activates inwardly rectifying K(+) channels, which reduces the basal firing frequency of dopamine (DA) neurons of the ventral tegmental area (VTA)
	plays a functional role in the regulation of brain monoamines and the mediation of action of amphetamine-like psychostimulants
	role for TAAR1 in the functional regulation of monoamine transporters and the neuronal regulatory mechanisms that modulate dopaminergic activity
	is potentially a negative modulator of monoaminergic neurotransmission
	affects the dopaminergic system by regulating the firing rate of dopaminergic neurons or by altering DRD2 responsiveness to ligands
	TAAR1 and DRD2 have functional and physical interactions that could be critical for the modulation of the dopaminergic system by TAAR1

ANIMAL & CELL MODELS

Taar1 knockout mice display increased sensitivity to amphetamine as revealed by enhanced amphetamine-triggered increases in locomotor activity and augmented striatal release of dopamine compared with wild-type animals
