Predicted to enable electron transfer activity. Predicted to be involved in mitochondrial electron transport, succinate to ubiquinone. Predicted to be located in mitochondrial inner membrane. Predicted to be part of respiratory chain complex II (succinate dehydrogenase). Is expressed in adult head; spermatozoon; and testis. Human ortholog(s) of this gene implicated in Carney-Stratakis syndrome; gastrointestinal stromal tumor; lung non-small cell carcinoma; and paraganglioma. Orthologous to human SDHC (succinate dehydrogenase complex subunit C).
