Among glycerophospholipids, PCs constitute the major membrane components of circulating lipoproteins (Cole et al., 2012), and PC-transfer protein (PC-TP) promotes cellular lipid efflux in nascent high-density lipoprotein (HDL) formation mediated by apolipoprotein A1 (apo-A1) (Baez et al., 2002), the major protein component of HDLs.
