Recombinant Human Heme oxygenase 2 (HMOX2)

Uniprot Id

P30519

Target Species

Human

Target Name

HMOX2

Target Full Name

Heme oxygenase 2

Target Function

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. Heme oxygenase 2 could be implicated in the production of carbon monoxide in brain where it could act as a neurotransmitter.

Target Subcellular Location

Microsome. Endoplasmic reticulum.

Target Protein Families

Heme oxygenase family

Target Synonyms

Heme oxygenase (decycling) 2; Heme oxygenase (decyclizing) 2; Heme oxygenase 2; HMOX 2; Hmox2; HMOX2 protein; HMOX2_HUMAN; HO 2; HO-2; HO2; OTTHUMP00000159847

Target Background

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. Several alternatively spliced transcript variants encoding three different isoforms have been found for this gene.
