Abstract excerpt
BACKGROUND: Previous studies have shown that etomidate modulates γ-aminobutyric acid type A receptors by binding at the β-α subunit interface within the transmembrane domain of receptors that incorporate β2 or β3 subunits. Introducing an asparagine-to-methionine (N265M) mutation at position 265 of the β3 subunit, which sits within the etomidate-binding site, attenuates the hypnotic effect of etomidate in vivo. It...
