Detailed biochemical studies have demonstrated that cPLA2γ shows remarkable substrate specificity—preferentially generating 2‐arachidonoyl lysophosphatidylcholine from its substrates—and possesses robust lysophospholipase and transacylase activities. These catalytic actions serve both to liberate key lipid mediators, such as arachidonic acid, and to clear accumulating lysophospholipids that might otherwise be toxic. In addition, cPLA2γ localizes to several critical intracellular compartments (including the endoplasmic reticulum, mitochondria, and peroxisomes), thereby contributing to lipid plasticity and the regulation of energy metabolism as observed in cardiac tissues under metabolic stress."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "1", "end_ref": "5"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nBeyond its core enzymatic functions, PLA2G4C plays a key role in membrane remodeling and the production of bioactive lipid second messengers that are essential for cell signaling. In the uterine endometrium, for example, its activity contributes to the regulation of prostaglandin synthesis; in breast cancer and other cell migration models, altering cPLA2γ expression notably affects chemotactic responses, including the modulation of Akt, integrins, and cytoskeletal regulators. Moreover, evidence indicates that cPLA2γ influences immune cell function by regulating macrophage differentiation and polarization, thereby linking its lipid remodeling activities with the orchestration of inflammatory responses."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "6", "end_ref": "9"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nGenetic investigations further underscore the broad biological significance of PLA2G4C.

In the context of antipsychotic treatment, specific PLA2G4C gene variants have also been examined for their potential to influence clinical symptoms and metabolic parameters.
