Abstract

Presynaptic norepinephrine transporters (NETs) mediate the rapid clearance of norepinephrine from synaptic spaces. NET is a member of the Na+ and Cl− -coupled neurotransmitter transporter gene family, which also includes the serotonin and dopamine transporters. Recent studies reveal that these transporter molecules might be a dynamic component of synaptic plasticity, rather than a constitutive determinant of neurotransmitter levels in synaptic spaces. Recognition that cellular signaling molecules and transporter ligands, including cocaine, amphetamines, and antidepressants, can modify transporter intrinsic activity, trafficking, phosphorylation, and protein levels suggests opportunities for revealing unknown mechanisms of drug action. Control of these properties of transporter function may allow for the development of new strategies to modulate monoaminergic neurotransmission and identify regulatory pathways that may be compromised in psychiatric, neurologic, and neurodegenerative disorders.
