Predicted to enable alcohol-forming very long-chain fatty acyl-CoA reductase activity. Predicted to be involved in long-chain fatty-acyl-CoA metabolic process. Predicted to act upstream of or within lipid metabolic process. Predicted to be located in peroxisomal membrane. Predicted to be active in peroxisome. Is expressed in several structures, including nervous system; notochord; pronephric duct; solid lens vesicle; and ventral mesenchyme. Human ortholog(s) of this gene implicated in rhizomelic chondrodysplasia punctate type 4. Orthologous to human FAR1 (fatty acyl-CoA reductase 1).
