MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Complex II of the respiratory chain, which is specifically involved in the oxidation of succinate, carries electrons from FADH to CoQ. The complex is composed of four nuclear-encoded subunits and is localized in the mitochondrial inner membrane. The iron-sulfur subunit is highly conserved and contains three cysteine-rich clusters which may comprise the iron-sulfur centers of the enzyme. Sporadic and familial mutations in this gene result in paragangliomas and pheochromocytoma, and support a link between mitochondrial dysfunction and tumorigenesis. [provided by RefSeq, Jul 2008]
PHENOTYPE: The gene is involved in the hypoxia-induced RNA editing pathway in monocytes. Heterozygous compound KOs show reduced increase in blood hemoglobin under hypoxic conditions. Homozygous inactivation of this gene results in complete embryonic lethality. [provided by MGI curators]
