  ID: HMOX2_HUMAN
DESCRIPTION: RecName: Full=Heme oxygenase 2; Short=HO-2; EC=1.14.99.3;
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.
CATALYTIC ACTIVITY: Heme + 3 AH(2) + 3 O(2) = biliverdin + Fe(2+) + CO + 3 A + 3 H(2)O.
SUBCELLULAR LOCATION: Microsome. Endoplasmic reticulum.
INDUCTION: Heme oxygenase 2 activity is non-inducible.
SIMILARITY: Belongs to the heme oxygenase family.
SIMILARITY: Contains 2 HRM (heme regulatory motif) repeats.
WEB RESOURCE: Name=NIEHS-SNPs; URL="http://egp.gs.washington.edu/data/hmox2/";

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
