• Pathways

At the plasma membrane, phosphatidylcholine (PC) is hydrolyzed, removing one of its acyl groups, to 1-acyl lysophosphatidylcholine (LPC) by secretory phospholipase A2 proteins (Singer et al. 2002, Ishizaki et al. 1999). These include: Group IB (PLA2G1B) (Grataroli et al. 1982); Group IIA (PLA2G2A) (Seilhamer et al. 1989); Group IID (PLA2G2D) (Ishizaki et al. 1999); Group IIE (PLA2G2E) (Suzuki et al. 2000); Group IIF (PLA2G2F) (Valentin et al. 2000); Group III (PLA2G3) (Murakami et al. 2003, Murakami et al. 2005); Calcium-dependent Group V (PLA2G5) (Chen et al. 1994); Group X (PLA2G10) (Cupillard et al. 1997, Pan et al. 2002); and Group XIIA (PLA2G12A) (Gelb et al. 2000, Murakami et al. 2003).
