At the endoplasmic reticulum (ER) membrane, phosphatidylinositol (PI) is hydrolyzed, and has one of its acyl chains cleaved off, by membrane-associated phospholipase A2 gamma 2A (PLA2G2A) (Singer et al. 2002) or by cytosolic phospholipase A2 gamma (PLA2G4C) (Ghomashchi et al. 2010), to form 1-acyl lysophosphatidylinositol (LPI).
