WebGABA A Receptor and Zolpidem. GABA A receptors are heterooligomeric intrinsic membrane proteins that are comprised of five subunits from seven main subunit families (α, β, γ, δ, ε, θ, and ρ). Many of these subunits exist as multiple isoforms, each of which is encoded by a different gene (e.g., α1–6, β1–4, γ1–3, and ρ1–3).
