Summary: Enables NADP binding activity; lithocholic acid binding activity; and steroid dehydrogenase activity, acting on the CH-OH group of donors, NAD or NADP as acceptor. Involved in steroid metabolic process. Predicted to be located in cytoplasm. Predicted to be active in cytosol. Human ortholog(s) of this gene implicated in 46,XY sex reversal 8. Orthologous to human AKR1C1 (aldo-keto reductase family 1 member C1); AKR1C2 (aldo-keto reductase family 1 member C2); and AKR1C4 (aldo-keto reductase family 1 member C4).

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.
