**Background of PLA2G3 Recombinant Protein**
Phospholipase A2 Group III (PLA2G3), a member of the secreted phospholipase A2 (sPLA2) family, is an enzyme that hydrolyzes 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, such as prostaglandins and leukotrienes, which play critical roles in inflammation, immune responses, and cellular signaling. PLA2G3. also termed sPLA2-III, is distinct in its structural features, including a long N-terminal domain and a central sPLA2 catalytic domain, enabling unique substrate interactions and regulatory functions.
Biologically, PLA2G3 is implicated in lipid metabolism, membrane remodeling, and pathological conditions like allergic inflammation, cancer, and metabolic disorders. Studies suggest it influences epidermal hyperplasia and skin barrier function, with knockout models revealing its role in mitigating hyperimmunoglobulin E syndrome-like symptoms. Additionally, PLA2G3 may regulate extracellular vesicle release and intercellular communication.
Recombinant PLA2G3 protein is produced via heterologous expression systems (e.g., mammalian or insect cells) to ensure proper post-translational modifications and enzymatic activity. This engineered protein is pivotal in functional studies, inhibitor screening, and elucidating mechanisms of lipid-mediated signaling. Its availability accelerates research into sPLA2-driven diseases and supports therapeutic development targeting lipid pathways.
Overall, PLA2G3 recombinant protein serves as a vital tool for dissecting the enzyme’s biological roles and exploring its therapeutic potential in inflammation-related and metabolic diseases.
