    basic FUNCTION
  • hydrolase activity, acting on carbon-nitrogen bonds in linear amides
  • Golgi enzyme, regulating ITGB1 maturation by controlling the generation of sphingosine
  • plays an important role in cellular responses by regulating the hydrolysis of ceramides in cells
  • has likely broad substrate specificity and requires Ca(2+) for its activity and ACER2 has the cytosolic C terminus and luminal N terminus, which are essential for its activity, correct cellular localization, and regulation for protein glycosylation (PMIDS:
  • alkaline ceramidase activity is important for the generation of SPH, the S1P precursor in erythrocytes
  • ACER2 upregulation mediates PCD in response to DNA damage through sphingosine
  • ACER2/sphingosine pathway mediates programmed cell death (PCD) in response to DNA damage through ROS production
  • is involved in programed cell death in response to DNA damage
  • ACER2 required Ca2+ for both its in vitro and cellular activities and its N-terminal tail is necessary for both ACER2 activity and Golgi localization
  • plays a key role in the maintenance of high plasma levels of sphingoid base-1-phosphates-S1P and dihydrosphingosine (dhSPH)-by controlling the generation of sphingoid bases-SPH and dhSPH-in hematopoietic cells
