WebMay 1, 2004 · Phospholipase A 2 type IVA (IVAPLA 2) is a cytosolic enzyme that on activation selectively releases arachidonic acid (AA) from cell membrane phospholipids.Both AA and lysophospholipid, products of the enzymic reaction, can function as signal transducers in cellular interactions. The enzyme is present in most cells, including … WebPhospholipase A2 (PLA2) is the key enzyme that initiates the arachidonic acid cascade, which leads to the generation of multiple eicosanoid products. Many of these products are believed to play an important role in the inflammatory process. Activation of PLA2 is observed under pathological conditions where inflammation is present.
