title: Molecular aspects of intracellular sterol esterification: the acyl coenzyme A: cholesterol acyltransferase reaction.
abstract: The conversion of cholesterol to an esterified storage form by the enzyme acyl-coenzyme A: cholesterol acyltransferase, is a critical component of sterol and membrane homeostasis and represents a significant step in atherogenesis. The isolation in 1993 of the first molecular probe of acyl-coenzyme A: cholesterol acyltransferase provided a key to understanding this reaction and its regulation. The sequence is apparently ubiquitous in eukaryotes, often with multiple sequence homologs within an organism. Presented here is a review of the known molecular events that lead to intracellular sterol esterification.
