Predicted to enable very-long-chain enoyl-CoA reductase activity. Predicted to be involved in fatty acid elongation; sphingolipid metabolic process; and very long-chain fatty acid biosynthetic process. Predicted to act upstream of or within fatty acid biosynthetic process and steroid biosynthetic process. Predicted to be located in endoplasmic reticulum. Predicted to be integral component of endoplasmic reticulum membrane. Is expressed in several structures, including alimentary system; nervous system; respiratory system; sensory organ; and skeleton. Human ortholog(s) of this gene implicated in autosomal recessive non-syndromic intellectual disability. Orthologous to human TECR (trans-2,3-enoyl-CoA reductase).
