Predicted to enable electron transfer activity; flavin adenine dinucleotide binding activity; and succinate dehydrogenase (ubiquinone) activity. Predicted to be involved in mitochondrial electron transport, succinate to ubiquinone; nervous system development; and succinate metabolic process. Located in mitochondrion. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and sensory organ. 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). [provided by Alliance of Genome Resources, Apr 2022]
