Conformational dynamics of the human serotonin transporter during substrate and drug binding

The serotonin transporter (SERT) is responsible for re-uptake of serotonin into the presynaptic neuron and plays a key role in synaptic transmission. Here, the authors use hydrogen-deuterium exchange mass spectrometry to probe the conformational dynamics of human SERT in the absence and presence of known substrates and targeted drugs
