A human skin multifunctional O-acyltransferase that catalyzes the synthesis of acylglycerols, waxes, and retinyl esters.

ABSTRACT: Acyl-CoA-dependent O-acyltransferases catalyze reactions in which fatty acyl-CoAs are joined to acyl acceptors containing free hydroxyl groups to produce neutral lipids. In this report, we characterize a human multifunctional O-acyltransferase (designated MFAT) that belongs to the acyl-CoA:diacylglycerol acyltransferase 2/acyl-CoA:monoacylglycerol acyltransferase (MGAT) gene family and is highly expressed in the skin. Membranes of insect cells and homogenates of mammalian cells overexpressing MFAT exhibited significantly increased MGAT, acyl-CoA:fatty acyl alcohol acyltransferase (wax synthase), and acyl-CoA:retinol acyltransferase (ARAT) activities, which catalyze the synthesis of diacylglycerols, wax monoesters, and retinyl esters, respectively. Furthermore, when provided with the approp
