- Description
- Predicted to enable electron transfer activity; flavin adenine dinucleotide binding activity; and succinate dehydrogenase (quinone) activity. Predicted to be involved in mitochondrial electron transport, succinate to ubiquinone. Predicted to act upstream of or within electron transport chain. Predicted to be located in mitochondrial inner membrane. Predicted to be part of respiratory chain complex II (succinate dehydrogenase). Is expressed in several structures, including adaxial cell; alar plate midbrain region; eye; musculature system; and pleuroperitoneal region. Human ortholog(s) of this gene implicated in Leigh disease; dilated cardiomyopathy 1GG; lung non-small cell carcinoma; mitochondrial complex II deficiency; and paraganglioma. Orthologous to human SDHA (succinate dehydrogenase complex flavoprotein subunit A).
