At the endoplasmic reticulum (ER) membrane, phosphatidylserine (PS) is hydrolyzed, and has one of its acyl chains cleaved off, by cytosolic phospholipase A2 alpha/delta/zeta (PLA2G4A/D/F) (Ghomashchi et al. 2010). This produces 2-acyl lysophosphatidylserine (LPS). Cytosolic phospholipase A2 enzymes show not only PLA2 hydrolyzing activity to form the 1-acyl lysophospholipid but also have a degree of PLA1 activity, producing a 2-acyl lysophospholipid.
