FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Heme oxygenase, an essential enzyme in heme catabolism, cleaves heme to form biliverdin, which is subsequently converted to bilirubin by biliverdin reductase, and carbon monoxide, a putative neurotransmitter. Heme oxygenase activity is induced by its substrate heme and by various nonheme substances. Heme oxygenase occurs as 2 isozymes, an inducible heme oxygenase-1 and a constitutive heme oxygenase-2. HMOX1 and HMOX2 belong to the heme oxygenase family. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for targeted null mutations exhibit low serum iron levels, increased hepatic and renal iron, oxidative damage, tissue injury, chronic inflammation, reduced neuronal proliferation, and increased sensitivity to hypoxia. [provided by MGI curators]
