Function

DAT_DROME Sodium-dependent dopamine transporter which terminates the action of dopamine by its high affinity sodium-dependent reuptake into presynaptic terminals (PubMed:11125028, PubMed:12606774, PubMed:24037379, PubMed:25970245). Also transports tyramine and norepinephrine, shows less efficient transport of octopamine and does not transport serotonin (PubMed:11125028, PubMed:12606774). Plays a role in the regulation of the rest/activity cycle (PubMed:16093388, PubMed:25232310).[1] [2] [3] [4] [5] [6]

Publication Abstract from PubMed

Most antidepressants elicit their therapeutic benefits through selective blockade of Na+/Cl--coupled neurotransmitter transporters. Here we report X-ray structures of the Drosophila melanogaster dopamine transporter in complexes with the polycyclic antidepressants nisoxetine or reboxetine. The inhibitors stabilize the transporter in an outward-open conformation by occupying the substrate-binding site. These structures explain how interactions between the binding pocket and substituents on the aromatic rings of antidepressants modulate drug-transporter selectivity.
