Acyltransferase that catalyzes the formation of ester bonds between fatty alcohols and fatty acyl-CoAs to form wax monoesters (PubMed:15671038). Shows a strong preference for decyl alcohol (C10), with less activity towards C16 and C18 alcohols (PubMed:15671038). Shows a strong preference for saturated acyl-CoAs (PubMed:15671038). a fatty acyl-CoA + a long chain fatty alcohol = a wax ester + CoA (9Z)-octadecenoyl-CoA + 1,2-di-(9Z-octadecenoyl)-sn-glycerol = 1,2,3-tri-(9Z-octadecenoyl)-glycerol + CoA (9Z)-octadecenoyl-CoA + hexadecan-1-ol = CoA + hexadecanyl (9Z)-octadecenoate (9Z)-octadecenoyl-CoA + decan-1-ol = 1-O-decyl-(9Z)-octadecenoate + CoA (9Z)-hexadecen-1-ol + (9Z)-octadecenoyl-CoA = 1-O-(9Z)-hexadecenyl (9Z)-octadecenoate + CoA (9Z)-octadecenoyl-CoA + octadecan-1-ol = 1-O-octadecyl (9Z)-octadecenoate + CoA (9Z)-octadecen-1-ol + (9Z)-octadecenoyl-CoA = 1-O-(9Z)-octadecenyl (9Z)-octadecenoate + CoA hexadecan-1-ol + hexadecanoyl-CoA = CoA + hexadecanyl hexadecanoate (9Z)-hexadecenoyl-CoA + hexadecan-1-ol = 1-O-hexadecyl (9Z)-hexadecenoate + CoA hexadecan-1-ol + octadecanoyl-CoA = CoA + hexadecanyl octadecanoate (9Z)-octadecenoyl-CoA + eicosan-1-ol = 1-O-eicosanyl (9Z)-octadecenoate + CoA Predominantly expressed in skin, where it is limited to the sebaceous gland. Expressed in more mature, centrally located cells just before their rupture and sebum release. Also expressed in all tissues except spleen. Expressed at higher level in thymus, prostate and testis. Belongs to the diacylglycerol acyltransferase family.
