Also known as: Cype; CYPIIB2
Summary: Enables steroid hydroxylase activity. Involved in several processes, including nicotine metabolic process; response to calcium ion; and xenobiotic metabolic process. Predicted to be located in endoplasmic reticulum membrane. Predicted to be active in cytoplasm and intracellular membrane-bounded organelle. 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]

What's a GeneRIF?

stimulation of hepatic heme oxygenase-1 expression by ascorbic acid deficiency caused the decrease in CYP content in liver
Title: Ascorbic acid deficiency decreases hepatic cytochrome P-450, especially CYP2B1/2B2, and simultaneously induces heme oxygenase-1 gene expression in scurvy-prone ODS rats.
LMP2 contributes to the NO-dependent degradation of CYP2B proteins, and induction of LMP2 may be involved in the potentiation of this degradation by IL-1.
Title: Nitric oxide-dependent CYP2B degradation is potentiated by a cytokine-regulated pathway and utilizes the immunoproteasome subunit LMP2.

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.
