产品描述:
Peroxiredoxin-6 (Prdx6) is a bifunctional enzyme that has both non-selenium glutathione peroxidase (GPX) and phospholipase A2 (PLA2) activities.{9012} Its PLA2 activity is calcium-independent, functions optimally in acidic (pH = 4) conditions, and facilitates the intracellular processing of surfactant lipids, including dipalmitoylphosphatidylcholine (DPPC).{9012,27803,5680} MJ33 is a selective, reversible inhibitor of the acidic, calcium-independent (ai)PLA2 activity of Prdx6, with optimal inhibition achieved at an MJ33 concentration of 3 mol%.{3982,3927,27802} It blocks the degradation of DPPC in both whole lung and isolated alveolar type II epithelial cells.{27803} MJ33 has been used to examine the role of Prdx6 PLA2 activity in the activation of type 2 NADPH oxidase and in the regulation of Prdx6 PLA2 activity by phosphorylation.{27804,27805}
