**Background of GSTP2 Recombinant Protein**
Glutathione S-transferase Pi 2 (GSTP2) is a member of the glutathione S-transferase (GST) family, a group of enzymes critical for detoxification and cellular defense against oxidative stress. GSTP2 catalyzes the conjugation of glutathione to electrophilic substrates, facilitating the neutralization of reactive oxygen species (ROS), xenobiotics, and carcinogens. It shares structural and functional homology with GSTP1. a well-studied isoform implicated in drug resistance and cancer progression. However, GSTP2 exhibits distinct tissue-specific expression patterns, with higher levels observed in skin, mammary glands, and prostate tissues.
The recombinant GSTP2 protein is engineered via molecular cloning, typically expressed in prokaryotic systems like *E. coli* to ensure high yield and purity. This recombinant form retains the enzymatic activity of the native protein, enabling researchers to study its biochemical properties, substrate specificity, and interactions with inhibitors or therapeutic agents. Its production often involves affinity chromatography for purification, leveraging tags such as His-tag or GST-tag for efficient isolation.
GSTP2 has garnered interest in biomedical research due to its dual role in oxidative stress regulation and potential involvement in disease pathways. While its overexpression in certain cancers suggests a protective role against chemotherapy-induced damage, conflicting studies highlight context-dependent functions, complicating its classification as purely oncogenic or tumor-suppressive. Additionally, GSTP2 polymorphisms have been linked to susceptibility to inflammatory disorders and metabolic diseases.
Current applications of recombinant GSTP2 include enzymology assays, drug discovery screens, and mechanistic studies exploring its role in cellular redox homeostasis. Its utility as a tool for developing isoform-specific GST inhibitors is also under exploration, aiming to overcome limitations posed by the structural similarity among GST family members. Ongoing research seeks to clarify its pathophysiological relevance, particularly in cancer and detoxification pathways, to inform therapeutic strategies.
