Previous GeneCards Identifiers for HMOX1 Gene
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]
GeneCards Summary for HMOX1 Gene
HMOX1 (Heme Oxygenase 1) is a Protein Coding gene. Diseases associated with HMOX1 include Heme Oxygenase 1 Deficiency and Pulmonary Disease, Chronic Obstructive. Among its related pathways are Photodynamic therapy-induced NFE2L2 (NRF2) survival signaling and Validated transcriptional targets of AP1 family members Fra1 and Fra2. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and oxidoreductase activity. An important paralog of this gene is HMOX2.
UniProtKB/Swiss-Prot Summary for HMOX1 Gene
Heme oxygenase cleaves the heme ring at the alpha methene bridge to form biliverdin. Biliverdin is subsequently converted to bilirubin by biliverdin reductase. Under physiological conditions, the activity of heme oxygenase is highest in the spleen, where senescent erythrocytes are sequestrated and destroyed. Exhibits cytoprotective effects since excess of free heme sensitizes cells to undergo apoptosis.
Heme oxygenase (HO) catalyzes the degradation of heme. It is a membrane-bound enzyme that cleaves the heme ring at the alpha-methene bridge to produce bilverdin (which is metabolized further by bilirubin reductase to form bilirubin), iron and carbon monoxide.
