Cyp2a3 cytochrome P450, family 2, subfamily a, polypeptide 3 [Rattus norvegicus (Norway rat)] - Gene

Summary

Official Symbol: Cyp2a3provided by RGD
Official Full Name: cytochrome P450, family 2, subfamily a, polypeptide 3provided by RGD
Primary source: RGD:2465
See related: EnsemblRapid:ENSRNOG00000068556 AllianceGenome:RGD:2465
Gene type: protein coding
RefSeq status: VALIDATED
Organism: Rattus norvegicus
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Rattus
Also known as: Cyp2a3a; RATCYP2A3A
Summary: Predicted to enable arachidonate epoxygenase activity; heme binding activity; and oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen, reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen. Predicted to be involved in several processes, including coumarin metabolic process; epoxygenase P450 pathway; and response to stilbenoid. Predicted to be located in endoplasmic reticulum membrane. Predicted to be active in cytoplasm and intracellular membrane-bounded organelle. Orthologous to human CYP2A13 (cytochrome P450 family 2 subfamily A member 13); CYP2A6 (cytochrome P450 family 2 subfamily A member 6); and CYP2A7 (cytochrome P450 family 2 subfamily A member 7).

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.
