ABHD3 hydrolytic activity is highly specific for medium chain (e.g., dimyristoylphosphatidylcholine) and oxidatively truncated (e.g., azelaoyl PAF) phospholipids. ABHD3-deficient mice are viable, fertile, and possess dramatically elevated medium chain phospholipids in tissues and in blood. Conversely, ectopic expression of ABHD3 prevents the accumulation of oxidized phospholipids in cells.
