Predicted to enable 3-hydroxyacyl-CoA dehydratase activity and enzyme binding activity. Predicted to be involved in fatty acid elongation; sphingolipid biosynthetic process; and very long-chain fatty acid biosynthetic process. Predicted to be located in endoplasmic reticulum. Predicted to be integral component of endoplasmic reticulum membrane. Orthologous to human HACD4 (3-hydroxyacyl-CoA dehydratase 4). [provided by Alliance of Genome Resources, Apr 2022]
