Vestibular modulation by stimulant derivatives in a pentameric ligand-gated ion channel.
Br.J.Pharmacol., 182:2790-2802, 2025

PubMed Abstract: Allosteric modulation of pentameric ligand-gated ion channels (pLGICs) are critical for the action of neurotransmitters and many psychoactive drugs. However, details of their modulatory mechanisms remain unclear, especially beyond the orthosteric neurotransmitter-binding sites. The recently reported prokaryotic symbiont of Tevnia jerichonana ligand-gated ion channel (sTeLIC), a pH-gated homologue of eukaryotic receptors in the pLGIC family, is thought to be modulated by aromatic compounds via a relatively uncharacterised modulatory site in the extracellular vestibule.
