S4-based voltage sensors have three major conformations

CA Villalba-Galea, W Sandtner… - Proceedings of the …, 2008 - National Acad Sciences
Voltage sensors containing the charged S4 membrane segment display a gating charge vs.
voltage (Q–V) curve that depends on the initial voltage. The voltage-dependent …

[HTML][HTML] The mechanistic basis for noncompetitive ibogaine inhibition of serotonin and dopamine transporters

…, M Freissmuth, G Rudnick, HH Sitte, W Sandtner - Journal of Biological …, 2012 - ASBMB
Ibogaine, a hallucinogenic alkaloid proposed as a treatment for opiate withdrawal, has
been shown to inhibit serotonin transporter (SERT) noncompetitively, in contrast to all other …

[HTML][HTML] 'Second-generation'mephedrone analogs, 4-MEC and 4-MePPP, differentially affect monoamine transporter function

…, A Seddik, T Stockner, M Holy, W Sandtner… - …, 2015 - nature.com
The nonmedical use of synthetic cathinones is increasing on a global scale. 4-Methyl-N-methylcathinone
(mephedrone) is a popular synthetic cathinone that is now illegal in the United …

Serotonin-transporter mediated efflux: a pharmacological analysis of amphetamines and non-amphetamines

B Hilber, P Scholze, MM Dorostkar, W Sandtner… - …, 2005 - Elsevier
The physiological function of neurotransmitter transporter proteins like the serotonin
transporter (SERT) is reuptake of neurotransmitter that terminates synaptic serotoninergic …

[HTML][HTML] Unifying concept of serotonin transporter-associated currents

…, S Boehm, G Rudnick, HH Sitte, W Sandtner - Journal of Biological …, 2012 - ASBMB
Serotonin (5-HT) uptake by the human serotonin transporter (hSERT) is driven by ion
gradients. The stoichiometry of transported 5-HT and ions is predicted to result in electroneutral …

Serotonin transport in the 21st century

G Rudnick, W Sandtner - Journal Of general physiology, 2019 - rupress.org
Serotonin (5-hydroxytryptamine [5-HT]) is accumulated within nerve endings by the serotonin
transporter (SERT), which terminates its extracellular action and provides cytoplasmic 5-HT …

Structure-based discovery of conformationally selective inhibitors of the serotonin transporter

…, VM Pogorelov, P Lak, H O'Donnell, W Sandtner… - Cell, 2023 - cell.com
The serotonin transporter (SERT) removes synaptic serotonin and is the target of anti-depressant
drugs. SERT adopts three conformations: outward-open, occluded, and inward-open. …

[HTML][HTML] Serotonin-releasing agents with reduced off-target effects

…, F Deng, J Wan, M Holy, R Katamish, W Sandtner… - Molecular …, 2023 - nature.com
Increasing extracellular levels of serotonin (5-HT) in the brain ameliorates symptoms of
depression and anxiety-related disorders, eg, social phobias and post-traumatic stress disorder. …

Persistent binding at dopamine transporters determines sustained psychostimulant effects

…, J Maier, N Kastner, W Sandtner… - Proceedings of the …, 2023 - National Acad Sciences
Psychostimulants interacting with the dopamine transporter (DAT) can be used illicitly or for
the treatment of specific neuropsychiatric disorders. However, they can also produce severe …

Binding mode selection determines the action of ecstasy homologs at monoamine transporters

W Sandtner, T Stockner, PS Hasenhuetl, JS Partilla… - Molecular …, 2016 - ASPET
Determining the structural elements that define substrates and inhibitors at the monoamine
transporters is critical to elucidating the mechanisms underlying these disparate functions. In …
