Heme oxygenase 2 is an enzyme that in humans is encoded by the HMOX2 gene.{{cite journal | vauthors = McCoubrey WK, Ewing JF, Maines MD | title = Human heme oxygenase-2: characterization and expression of a full-length cDNA and evidence suggesting that the two HO-2 transcripts may differ by choice of polyadenylation signal | journal = Arch Biochem Biophys | volume = 295 | issue = 1 | pages = 13–20 | date = Jun 1992 | pmid = 1575508 | doi = 10.1016/0003-9861(92)90481-B | doi-access = free }}
Function
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 (this enzyme) belong to the heme oxygenase family.{{cite web | title = Entrez Gene: HMOX2 heme oxygenase (decycling) 2| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=3163}}
