β subunits of GABAA receptors form proton-gated chloride channels: Insights into the molecular basis.
Garifulina A, Friesacher T, Stadler M, Zangerl-Plessl EM, Ernst M, Stary-Weinzinger A, Willam A, Hering S. Garifulina A, et al. Commun Biol. 2022 Aug 3;5(1):784. doi: 10.1038/s42003-022-03720-2. Commun Biol. 2022. PMID: 35922471 Free PMC article.
In molecular dynamic simulations of the beta3 crystal structure protonation of H267 increased the formation of hydrogen bonds between H267 and E270 of the adjacent subunit leading to a pore stabilising ring formation and accumulation of Cl(-) within the transmembrane pore. …
