Summary: Enables oxidoreductase activity. Predicted to be involved in several processes, including cellular organofluorine metabolic process; nitrate catabolic process; and positive regulation of steroid biosynthetic process. Predicted to be located in intracellular membrane-bounded organelle. Predicted to be active in cytosol. Is expressed in several structures, including alimentary system; limb; metanephros; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in Antley-Bixler syndrome with disordered steroidogenesis; congenital adrenal hyperplasia; and cytochrome P450 oxidoreductase deficiency. Orthologous to human POR (cytochrome p450 oxidoreductase). [provided by Alliance of Genome Resources, Dec 2024]

Knockout of the cytochrome P450 reductase by CRISPR/Cas9 technology (POR(-/-)) in HEK293 cells overexpressing Nox4 or Nox5 did not interfere with ROS production in intact cells. However, POR(-/-) abolished the signal in NADPH-stimulated assays using membrane fractions from the very same cells. Moreover, membranes of rat smooth muscle cells treated with angiotensin II showed an increased NADPH-dependent signal with lucigen

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.
