Acyltransferase that catalyzes the formation of ester bonds between fatty alcohols and fatty acyl-CoAs to form wax monoesters (PubMed:15220349, PubMed:15671038, PubMed:16106050, PubMed:28420705). Shows a preference for medium chain acyl-CoAs from C12 to C16 in length and fatty alcohols shorter than C20, as the acyl donors and acceptors, respectively (PubMed:15220349, PubMed:15671038). Also possesses acyl- CoA retinol acyltransferase (ARAT) activity that preferentially esterifies 11-cis-retinol, a chromophore precursor of bleached opsin pigments in cone cells (PubMed:16106050, PubMed:24799687). Shows higher catalytic efficiency toward 11-cis-retinol versus 9-cis-retinol, 13- cis-retinol, and all-trans-retinol substrates (PubMed:24799687). {ECO:0000269|PubMed:15220349, ECO:0000269|PubMed:15671038, ECO:0000269|PubMed:16106050, ECO:0000269|PubMed:24799687, ECO:0000269|PubMed:28420705}. This is the function of Ensembl gene identifier ENSG00000147160 (AWAT2, acyl-CoA wax alcohol acyltransferase 2).
