**Background of gABRd Recombinant Protein**
The gABRd (gamma-aminobutyric acid type A receptor subunit delta) recombinant protein is a key component in studying the structure and function of GABA_A receptors, the primary inhibitory neurotransmitter receptors in the central nervous system. GABA_A receptors are ligand-gated ion channels that mediate fast synaptic inhibition, regulating neuronal excitability and contributing to processes like anxiety regulation, sleep, and seizure control. These receptors are pentameric assemblies, typically composed of combinations of α, β, γ, δ, ε, θ, or π subunits. The delta (δ) subunit, encoded by the *GABRD* gene, is notable for its extrasynaptic localization and role in mediating tonic inhibition, which provides sustained neuronal silencing.
Recombinant gABRd proteins are engineered using heterologous expression systems (e.g., mammalian or insect cells) to produce purified δ subunits for functional and structural studies. These proteins enable researchers to explore δ-containing receptor subtypes, which exhibit unique pharmacological properties, including high sensitivity to neurosteroids and ethanol, and reduced sensitivity to classical benzodiazepines. Dysregulation of δ-subunit-containing receptors has been implicated in neurological disorders such as epilepsy, mood disorders, and insomnia.
The development of gABRd recombinant proteins has advanced drug discovery by facilitating high-throughput screening of compounds targeting extrasynaptic GABA_A receptors. Additionally, these proteins aid in cryo-EM and X-ray crystallography studies, revealing molecular mechanisms of receptor activation, modulation, and allosteric regulation. By providing a controlled, scalable source of δ subunits, recombinant gABRd supports both basic research and therapeutic innovation for GABA-related pathologies.
