    Summary
    Enables retinol isomerase activity and sphingolipid delta-4 desaturase activity. Acts upstream of or within ceramide biosynthetic process and positive regulation of apoptotic process. Predicted to be located in mitochondrion. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in hypomyelinating leukodystrophy 18. Orthologous to human DEGS1 (delta 4-desaturase, sphingolipid 1). [provided by Alliance of Genome Resources, Nov 2024]

    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.
