CC -!- FUNCTION: Membrane-anchoring subunit of succinate dehydrogenase (SDH)
CC that is involved in complex II of the mitochondrial electron transport
CC chain and is responsible for transferring electrons from succinate to
CC ubiquinone (coenzyme Q).
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle.
CC -!- SUBUNIT: Component of complex II composed of four subunits: the
CC flavoprotein (FP) SDHA, iron-sulfur protein (IP) SDHB, and a cytochrome
CC b560 composed of SDHC and SDHD. {ECO:0000269|PubMed:15989954}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC Multi-pass membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the CybS family. {ECO:0000305}.
