背景信息

**Background of GABA(A)R α2 Recombinant Protein**

The γ-aminobutyric acid type A (GABA(A)) receptor is a ligand-gated ion channel central to inhibitory neurotransmission in the mammalian central nervous system. It is a heteropentameric complex, typically composed of combinations of α, β, γ, δ, ε, or θ subunits. Among these, the α2 subunit (encoded by *GABRA2*) plays a critical role in mediating synaptic and extrasynaptic GABAergic signaling, particularly in regions associated with anxiety, reward pathways, and neurodevelopmental processes. Dysregulation of GABA(A)Rs containing α2 subunits has been linked to neurological and psychiatric disorders, including epilepsy, anxiety disorders, and alcohol dependence.

Recombinant GABA(A)R α2 protein is engineered to study the structure, function, and pharmacology of this subunit in isolation or within defined receptor assemblies. Produced via heterologous expression systems (e.g., HEK293 cells or *Xenopus* oocytes), it enables precise investigation of α2-specific contributions to receptor kinetics, ligand binding (e.g., benzodiazepines), and allosteric modulation. This protein is vital for elucidating mechanisms underlying subunit-specific drug interactions, designing targeted therapies, and modeling pathogenic mutations. Its applications extend to electrophysiology, crystallography, and high-throughput drug screening, offering insights into GABA(A)R-related pathophysiology and therapeutic development.
