Summary: Predicted to enable sphingolipid delta-4 desaturase activity. Predicted to be involved in ceramide biosynthetic process. Predicted to act upstream of or within sphingolipid biosynthetic process. Predicted to be located in endoplasmic reticulum membrane. Predicted to be integral component of membrane. Is expressed in nervous system; neural crest; notochord; pronephric duct; and yolk syncytial layer. Used to study hypomyelinating leukodystrophy.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
