Gene Name AWAT2
Protein Type Enzyme
Biological Properties
General Function Involved in transferase activity, transferring acyl groups other than amino-acyl groups
Specific Function Acyltransferase that predominantly esterify long chain (wax) alcohols with acyl-CoA-derived fatty acids to produce wax esters. Wax esters are enriched in sebum, suggesting that it plays a central role in lipid metabolism in skin. Has no activity using decyl alcohol and significantly prefers the C16 and C18 alcohols. May also have 2-acylglycerol O-acyltransferase (MGAT) and acyl-CoA:retinol acyltransferase (ARAT) activities, to catalyze the synthesis of diacylglycerols and retinyl esters; however this activity is unclear in vivo.
Pathways
  • Retinol metabolism
  • Vitamin digestion and absorption
