GABA-A Receptor Benzodiazepines

GABA_A Receptor Subunits

The majority of human endogenous GABA_A receptors are composed of α1-, β2- and γ2-subunits in a 2:2:1 ratio (α2β2γ), however the exact subunit conformation is determined by the expression of different subunits in a given cell type. Some subunits are only expressed in specific brain areas, for example receptors containing the α2-subunit are found in regions where the α1-subunit is absent or expressed at low levels, such as the ...
