**Background of gABRg2 Recombinant Protein**
The gABRg2 recombinant protein is a engineered subunit of the gamma-aminobutyric acid type A (GABAA) receptor, a critical ligand-gated ion channel in the central nervous system. GABAA receptors mediate inhibitory neurotransmission by facilitating chloride ion influx upon GABA binding, regulating neuronal excitability. These receptors are heteropentamers, typically composed of combinations of α, β, and γ subunits. The γ2 subunit (encoded by *GABRG2*) plays a pivotal role in receptor trafficking, synaptic clustering, and benzodiazepine sensitivity, making it a focus in studies of neurological disorders like epilepsy, anxiety, and sleep disorders.
The recombinant gABRg2 protein is produced via molecular cloning, often expressed in mammalian cell systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications. Its design may include tags (e.g., His-tag) for purification and detection. Researchers utilize this protein to study subunit-specific interactions, receptor assembly, and pharmacology. For instance, gABRg2 helps elucidate how mutations (e.g., those linked to genetic epilepsy) disrupt receptor function or drug binding.
Additionally, gABRg2 is instrumental in structural studies (e.g., cryo-EM) to resolve receptor architecture and dynamics. Its recombinant form also aids in developing subunit-targeted therapies, as benzodiazepines and other modulators exhibit γ2-dependent effects. Beyond basic research, gABRg2 serves as a tool for high-throughput drug screening and personalized medicine approaches for GABA-related pathologies. Overall, this protein bridges molecular insights into GABAergic signaling with translational applications in neurology and psychiatry.
