Predicted to enable very-long-chain enoyl-CoA reductase activity. Predicted to be involved in very long-chain fatty acid biosynthetic process. Located in cytoplasm and endomembrane system. Is expressed in adult head and adult heart. Human ortholog(s) of this gene implicated in autosomal recessive intellectual developmental disorder 14 and catecholaminergic polymorphic ventricular tachycardia 3. Orthologous to several human genes including TECR (trans-2,3-enoyl-CoA reductase).
