Phospholipase A2 Group IVC (PLA2G4C) is a calcium-dependent cytosolic enzyme belonging to the phospholipase A2 (PLA2) superfamily, which catalyzes the hydrolysis of phospholipids at the sn-2 position to release free fatty acids, including arachidonic acid, and lysophospholipids. These products serve as precursors for bioactive lipid mediators like eicosanoids, which regulate inflammation, cellular signaling, and membrane homeostasis. Unlike other Group IV PLA2 isoforms (e.g., PLA2G4A), PLA2G4C exhibits distinct structural features, including a unique N-terminal domain and variable catalytic efficiency, suggesting specialized roles in specific tissues. It is expressed predominantly in the brain, reproductive organs, and endocrine tissues, implicating potential functions in neurobiology, steroidogenesis, or reproductive physiology.
Recombinant human PLA2G4C protein is engineered using heterologous expression systems (e.g., E. coli, mammalian cells) to enable functional studies, structural analysis, and inhibitor screening. Its recombinant form retains enzymatic activity, facilitating research into its regulatory mechanisms and pathophysiological relevance. Dysregulation of PLA2G4C has been linked to neurological disorders, cancer, and metabolic syndromes, though its precise contributions remain under investigation. As a therapeutic target, PLA2G4C offers potential for modulating lipid-mediated pathways in disease contexts. Current studies focus on elucidating its substrate specificity, interaction partners, and role in lipid signaling networks.
