Predicted to enable fatty acid elongase activity. Predicted to be involved in fatty acid biosynthetic process and sphingolipid biosynthetic process. Predicted to act upstream of or within fatty acid biosynthetic process. Predicted to be located in endoplasmic reticulum and membrane. Predicted to be active in endoplasmic reticulum membrane. Is expressed in EVL; periderm; peripheral olfactory organ; and pharynx. Orthologous to human ELOVL7 (ELOVL fatty acid elongase 7).
