AWAT2 (Acyl-CoA wax alcohol acyltransferase 2, also known as MFAT and DC4) associated with the endoplasmic reticulum membrane catalyzes the reaction of atROL (all-trans retinol) and PALM-CoA (palmitoyl-CoA) to form the ester retinyl palmitate. This ester is thought to provide an inactive storage form of retinol and might play a role in protecting skin, where AWAT2 is most abundant from the effects of UV light (Arne et al. 2017; Yen et al. 2005).
