This enzyme is also called alkyllyso-GP:acetyl-CoA acetyltransferase.

Acetyl-CoA acetyltransferase, mitochondrial also known as acetoacetyl-CoA thiolase, is an enzyme that in humans is encoded by the ACAT1 (Acetyl-Coenzyme A acetyltransferase 1) gene.

Acetyl-CoA acetyltransferase, cytosolic, also known as cytosolic acetoacetyl-CoA thiolase, is an enzyme that in humans is encoded by the ACAT2 (acetyl-Coenzyme A acetyltransferase 2) gene that is responsible for the synthesis of cholesteryl esters which are part of lipoproteins containing apoB.
