**Background of ABAT Recombinant Protein**
ABAT (4-aminobutyrate aminotransferase), also known as GABA transaminase, is a mitochondrial enzyme critical in regulating the neurotransmitter γ-aminobutyric acid (GABA), the primary inhibitory neurotransmitter in the central nervous system. ABAT catalyzes the conversion of GABA into succinic semialdehyde, a key step in the GABA shunt pathway that links neurotransmitter metabolism to the tricarboxylic acid (TCA) cycle. Dysregulation of ABAT activity is associated with neurological disorders, including epilepsy, Alzheimer’s disease, and GABA-related metabolic imbalances.
Recombinant ABAT protein is produced using biotechnological platforms, such as *E. coli* or mammalian expression systems, to enable large-scale, high-purity production. The recombinant form retains the enzymatic activity and structural features of native ABAT, making it a valuable tool for *in vitro* studies. Researchers often engineer the protein with affinity tags (e.g., His-tag) to facilitate purification via chromatography techniques.
ABAT recombinant protein is widely used in biochemical and pharmacological research. It serves as a target for drug discovery, particularly for developing inhibitors that modulate GABA levels to treat neurological conditions. For example, ABAT inhibitors are explored as anticonvulsants to enhance GABA-mediated neuronal inhibition. Additionally, the protein aids in structural studies (e.g., X-ray crystallography) to elucidate substrate-binding mechanisms and catalytic pathways.
Beyond therapeutics, ABAT recombinant protein is employed in diagnostic assays and disease modeling, helping to unravel GABA metabolism’s role in health and disease. Its availability accelerates research into metabolic disorders, such as GABA-transaminase deficiency, a rare genetic condition causing developmental delays and seizures.
In summary, ABAT recombinant protein bridges fundamental neuroscience and translational medicine, offering insights into GABAergic signaling and therapeutic innovation for neurological diseases.
