The function of FAR2 (fatty acyl-CoA reductase 2, ENSG00000064763) is as follows. Catalyzes the reduction of saturated but not unsaturated C16 or C18 fatty acyl-CoA to fatty alcohols (FAls) (PubMed:15220348). A lower activity can be observed with shorter fatty acyl-CoA substrates (PubMed:15220348). Can produce very long-chain and ultra long-chain FAls, regardless of whether they have a straight or branched chain (PubMed:35238077). Involved in the production of ether lipids/plasmalogens and wax monoesters whose synthesis requires FAls as substrates (PubMed:24108123, PubMed:35238077). {ECO:0000269|PubMed:15220348, ECO:0000269|PubMed:24108123, ECO:0000269|PubMed:35238077}.
