Summary: Predicted to enable retinol isomerase activity and sphingolipid delta-4 desaturase activity. Predicted to be involved in ceramide biosynthetic process and myelin maintenance. Predicted to act upstream of or within positive regulation of apoptotic process. Predicted to be located in mitochondrion.

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.
