Biogenic amine transporter protein

Biogenic amine transporter proteins are membrane-bound proteins belonging to the solute carrier 6 (SLC6) family that mediate reuptake of key monoamine neurotransmitters—including dopamine, serotonin, and norepinephrine—into presynaptic neurons, thereby terminating synaptic transmission and controlling neurotransmitter homeostasis[1][6][3]. The main members are the dopamine transporter (DAT), norepinephrine transporter (NET), and serotonin transporter (SERT). These transporters are essential for normal central nervous system function, influence mood, motor activity, reward, attention, and multiple autonomic functions, and are primary targets for antidepressants, psychostimulants, and drugs of abuse[3][6][1]. Dysregulation is implicated in numerous neuropsychiatric and neurodegenerative disorders[3][6]. Their function is also increasingly recognized in non-neuronal cells such as immune cells, suggesting possible roles in neuroimmune interactions[4][8].
