Citation | Journal: J Neurochem / Year: 2024Title: Cryo-EM structure of the dopamine transporter with a novel atypical non-competitive inhibitor bound to the orthosteric site. Authors: Clara Nautrup Pedersen / Fuyu Yang / Samantha Ita / Yibin Xu / Ravikumar Akunuri / Sofia Trampari / Caroline Marie Teresa Neumann / Lasse Messell Desdorf / Birgit Schiøtt / Joseph M Salvino ...Authors: Clara Nautrup Pedersen / Fuyu Yang / Samantha Ita / Yibin Xu / Ravikumar Akunuri / Sofia Trampari / Caroline Marie Teresa Neumann / Lasse Messell Desdorf / Birgit Schiøtt / Joseph M Salvino / Ole Valente Mortensen / Poul Nissen / Azadeh Shahsavar / ![]() Abstract: The regulation of dopamine (DA) removal from the synaptic cleft is a crucial process in neurotransmission and is facilitated by the sodium- and chloride-coupled dopamine transporter DAT. ...The regulation of dopamine (DA) removal from the synaptic cleft is a crucial process in neurotransmission and is facilitated by the sodium- and chloride-coupled dopamine transporter DAT. Psychostimulant drugs, cocaine, and amphetamine, both block the uptake of DA, while amphetamine also triggers the release of DA. As a result, they prolong or even amplify neurotransmitter signaling. Atypical inhibitors of DAT lack cocaine-like rewarding effects and offer a promising strategy for the treatment of drug use disorders. Here, we present the 3.2 Å resolution cryo-electron microscopy structure of the Drosophila melanogaster dopamine transporter (dDAT) in complex with the atypical non-competitive inhibitor AC-4-248. The inhibitor partially binds at the central binding site, extending into the extracellular vestibule, and locks the transporter in an outward open conformation. Our findings propose mechanisms for the non-competitive inhibition of DAT and attenuation of cocaine potency by AC-4-248 and provide a basis for the rational design of more efficacious atypical inhibitors. | ||||||||||||||||||||||||||||||||||||
