**Background of GSTT2 Recombinant Protein**
Glutathione S-transferase theta 2 (GSTT2) is a member of the GST superfamily, a group of enzymes critical for cellular detoxification and oxidative stress response. GSTs catalyze the conjugation of glutathione (GSH) to electrophilic substrates, facilitating the neutralization and excretion of toxic compounds, including xenobiotics, environmental carcinogens, and reactive oxygen species (ROS). The theta class (GSTT), to which GSTT2 belongs, is distinguished by its substrate specificity and genetic variability. GSTT2 is located on chromosome 22q11.23 in humans and shares homology with GSTT1. though it exhibits unique enzymatic properties and tissue expression patterns.
Recombinant GSTT2 protein is produced using biotechnological methods, such as expression in bacterial (e.g., *E. coli*) or eukaryotic systems, enabling high-purity, functional enzyme production. This engineered protein retains the catalytic activity of native GSTT2. making it invaluable for studying detoxification mechanisms, metabolic pathways, and drug interactions. Researchers utilize GSTT2 recombinant protein to investigate its role in metabolizing specific carcinogens (e.g., halogenated hydrocarbons) and its potential association with disease susceptibility, including cancer and neurodegenerative disorders.
GSTT2 has garnered interest due to genetic polymorphisms affecting enzyme activity, which may influence individual responses to toxins or chemotherapeutic agents. Additionally, GSTT2's interaction with lipid peroxidation byproducts highlights its role in mitigating oxidative damage. The availability of recombinant GSTT2 facilitates drug discovery, biomarker development, and mechanistic studies, bridging gaps between genetic variations, enzymatic function, and health outcomes. Its applications extend to industrial biotechnology, where it may aid in designing biocatalysts for environmental toxin degradation.
