Identification
HMDB Protein ID HMDBP00499
Secondary Accession Numbers
  • 5746
Name Sterol O-acyltransferase 2
Synonyms
  1. ACAT-2
  2. Acyl-coenzyme A:cholesterol acyltransferase 2
  3. Cholesterol acyltransferase 2
Gene Name SOAT2
Protein Type Enzyme
Biological Properties
General Function Involved in acyl-CoA binding
Specific Function Plays a role in lipoprotein assembly and dietary cholesterol absorption. In addition to its acyltransferase activity, it may act as a ligase. May provide cholesteryl esters for lipoprotein secretion from hepatocytes and intestinal mucosa.
Pathways
