- Benzodiazepines modulate GABA(A) function by binding at the interface between alpha (α) and gamma (γ) subunits. Of the 6 α-subunits, only 4 (α-1, -2, -3, and -5) participate in the formation of this binding site. The above target is a collection of all α- and γ-subunits that are known to participate in the formation of the benzodiazepine binding site.

- The GABA(A) receptor is pentameric (i.e. comprising 5 subunit proteins) and therefore has a multitude of potential isoforms. The above target is a collection of all possible GABA(A) subunits that may participate in the formation of the pentameric receptor and is not meant to imply direct a drug-protein interaction for each individual subunit.
