    • CATEGORY enzyme
    SUBCELLULAR LOCALIZATION extracellular
    text extracellular PLA1s include hepatic lipase (HL)
    basic FUNCTION
  • glycoprotein that is synthesized and secreted primarily in the liver and involved in lipoproteins metabolism especially HDL
  • involved in lipase activity, plasma lipid transport
  • also mediates hepatic uptake of HDL cholesteryl esters and contributes to the reverse cholesterol transport system
  • lipolytic enzyme involved in several aspects of the same pathways of lipoprotein metabolism (van Haperen 2009)
