Summary: Predicted to enable enzyme binding activity; oxidoreductase activity, acting on the CH-CH group of donors, NAD or NADP as acceptor; and peptide antigen binding activity. Involved in several processes, including Ras protein signal transduction; negative regulation of cell population proliferation; and steroid metabolic process. Predicted to be located in endoplasmic reticulum and nucleus. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in lipid metabolism disorder. Orthologous to human DHCR24 (24-dehydrocholesterol reductase). [provided by Alliance of Genome Resources, Jul 2025]

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.
