== Function == | |||
[https://www.uniprot.org/uniprot/5HT3A_MOUSE 5HT3A_MOUSE] This is one of the several different receptors for 5-hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. This receptor is a ligand-gated ion channel, which when activated causes fast, depolarizing responses in neurons. It is a cation-specific, but otherwise relatively nonselective, ion channel. | |||

== Publication Abstract from PubMed == | |||
Vortioxetine (VTX) is a recently approved antidepressant that targets a variety of serotonin receptors. Here, we investigate the drug's molecular mechanism of operation at the serotonin 5-HT(3) receptor (5-HT(3)R), which features two properties: VTX acts differently on rodent and human 5-HT(3)R, and VTX appears to suppress any subsequent response to agonists. Using a combination of cryo-EM, electrophysiology, voltage-clamp fluorometry and molecular dynamics, we show that VTX stabilizes a resting inhibited state of the mouse 5-HT(3)R and an agonist-bound-like state of human 5-HT(3)R, in line with the functional profile of the drug. We report four human 5-HT(3)R structures and show that the human receptor transmembrane domain is intrinsically fragile. We also explain the lack of recovery after VTX administration via a membrane partition mechanism. | |||
