Predicted to enable 3-hydroxyacyl-CoA dehydratase activity. Predicted to be involved in fatty acid elongation; sphingolipid biosynthetic process; and very long-chain fatty acid biosynthetic process. Predicted to act upstream of or within fatty acid metabolic process. Predicted to be located in endoplasmic reticulum and membrane. Predicted to be active in endoplasmic reticulum membrane. Human ortholog(s) of this gene implicated in congenital myopathy. Orthologous to human HACD1 (3-hydroxyacyl-CoA dehydratase 1).
