Acyl CoA:cholesterol Acyltransferase Genes and Knockout Mice

Curr Opin Lipidol. 1998 Apr;9(2):119-23. doi: 10.1097/00041433-199804000-00007.


Acyl coenzyme A:cholesterol acyltransferase (ACAT) (EC is an enzyme, located in the endoplasmic reticulum of many types of cells, that catalyzes cholesterol ester formation from cholesterol and fatty acyl CoA substrates. Sterol esterification by ACAT or homologous enzymes is conserved in evolution dating back to yeast. The recent cloning of a human cDNA for ACAT, together with genome sequencing projects, has led to the identification of an ACAT gene family and provided molecular tools for determining ACAT's functions in vivo. Summarized here is the current knowledge concerning the molecular genetics of ACAT.
