Reaction: PC is hydrolyzed to 2-acyl LPC by PLA2G4C
- in pathway: Acyl chain remodelling of PC
At the endoplasmic reticulum (ER) membrane, phosphatidylcholine (PC) is hydrolyzed, and has one of its acyl chains cleaved off, by membrane-associated phospholipase A2 gamma 4C, PLA2G4C (Yamashita et al. 2005, Ghomashchi et al. 2010, Yamashita et al. 2009), to form 2-acyl lysophosphatidylcholine (LPC). Cytosolic phospholipase A2 enzymes show not only PLA2 hydrolysing activity to form the 1-acyl lysophospholipid but also have a degree of PLA1 activity, producing a 2-acyl lysophospholipid.
