  • mitochondria-associated nSMase (MA-nSMase)
    • basic FUNCTION
  • converting sphingomyelin to ceramide
  • one of the key enzymes involved in the generation of ceramide
  • having role in aging and inflammation
  • acts primarily as lyso-platelet-activating factor-phospholipase C (Marchesini 2003)
  • played a role in daunorubicin-induced cell death
  • may increase dopamine uptake through inducing ceramide production and thereby decreasing intracellular calcium levels
