Summary: Predicted to enable heme binding activity and monooxygenase activity. Involved in response to stilbenoid. Predicted to be located in endoplasmic reticulum membrane. Predicted to be active in cytoplasm and intracellular membrane-bounded organelle. Is expressed in liver. Human ortholog(s) of this gene implicated in several diseases, including acute myeloid leukemia; drug dependence (multiple); human immunodeficiency virus infectious disease; neonatal abstinence syndrome; and nicotine dependence. Orthologous to human CYP2B6 (cytochrome P450 family 2 subfamily B member 6). [provided by Alliance of Genome Resources, Dec 2024]

This study determined the regulatory region of the mouse Cyp2b9 gene and showed that FoxA2 is a predictably responsible nuclear factor in the female-predominant expression of the gene.
Title: Forkhead box A2-mediated regulation of female-predominant expression of the mouse Cyp2b9 gene.
During the maturation stage, CYP2B10 was expressed in both sexes, whereas CYP2B9 was diminished markedly in the males
Title: Sexual dimorphic expression of mouse hepatic CYP2B: alterations during development or after hypophysectomy.
These observations suggest that the sexually dimorphic expression of CYP2B9 is partly due to suppression by the masculine plasma GH profile and by glucocorticoid hormones.

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.
