**Background of PLA2G2E Recombinant Protein**
Phospholipase A2 Group IIE (PLA2G2E) is a member of the phospholipase A2 (PLA2) enzyme superfamily, which catalyzes the hydrolysis of phospholipids at the *sn*-2 position to release free fatty acids (e.g., arachidonic acid) and lysophospholipids. These products serve as precursors for bioactive lipid mediators involved in inflammation, cell signaling, and membrane remodeling. The PLA2G2E gene encodes a secreted, calcium-dependent enzyme classified under Group II PLA2s, which are characterized by their structural features, including a conserved catalytic site and disulfide bond patterns.
PLA2G2E has garnered interest due to its distinct tissue expression profile and potential roles in physiological and pathological processes. While its exact biological functions remain less defined compared to other Group II isoforms (e.g., PLA2G2A), studies suggest involvement in lipid metabolism, immune responses, and possibly carcinogenesis. Its expression has been detected in specific tissues, such as the skin, gastrointestinal tract, and certain tumors, hinting at context-dependent roles.
Recombinant PLA2G2E protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells) to enable functional and structural studies. This engineered protein retains enzymatic activity, allowing researchers to investigate substrate specificity, inhibitor screening, and regulatory mechanisms. Applications include elucidating its role in inflammatory pathways, exploring therapeutic targets for diseases like atherosclerosis or cancer, and studying its interactions with cell membranes or signaling molecules.
Despite its lower abundance relative to other PLA2s, PLA2G2E’s unique properties make it a valuable subject for understanding the diversity of lipid-mediated signaling and developing isoform-specific diagnostics or therapies. Ongoing research aims to clarify its physiological relevance and potential as a biomarker or drug target.
