== Function ==
[https://www.uniprot.org/uniprot/DAT_DROME 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).<ref>PMID:11125028</ref> <ref>PMID:12606774</ref> <ref>PMID:16093388</ref> <ref>PMID:24037379</ref> <ref>PMID:25232310</ref> <ref>PMID:25970245</ref>

== Publication Abstract from PubMed ==
Na(+)/Cl(-)-coupled biogenic amine transporters are the primary targets of therapeutic and abused drugs, ranging from antidepressants to the psychostimulants cocaine and amphetamines, and to their cognate substrates. Here we determine X-ray crystal structures of the Drosophila melanogaster dopamine transporter (dDAT) bound to its substrate dopamine, a substrate analogue 3,4-dichlorophenethylamine, the psychostimulants d-amphetamine and methamphetamine, or to cocaine and cocaine analogues. All ligands bind to the central binding site, located approximately halfway across the membrane bilayer, in close proximity to bound sodium and chloride ions. The central binding site recognizes three chemically distinct classes of ligands via conformational changes that accommodate varying sizes and shapes, thus illustrating molecular principles that distinguish substrates from inhibitors in biogenic amine transporters.
