CC   -!- FUNCTION: Plays an essential role in the assembly of succinate
CC       dehydrogenase (SDH), an enzyme complex (also referred to as respiratory
CC       complex II) that is a component of both the tricarboxylic acid (TCA)
CC       cycle and the mitochondrial electron transport chain, and which couples
CC       the oxidation of succinate to fumarate with the reduction of ubiquinone
CC       (coenzyme Q) to ubiquinol. Promotes maturation of the iron-sulfur
CC       protein subunit of the SDH catalytic dimer, protecting it from the
CC       deleterious effects of oxidants. May act together with SDHAF1.
CC       {ECO:0000250|UniProtKB:Q04401, ECO:0000250|UniProtKB:Q8SZ16}.
CC   -!- SUBUNIT: Interacts with the iron-sulfur protein subunit within the SDH
CC       catalytic dimer. {ECO:0000250|UniProtKB:Q04401}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC       {ECO:0000250|UniProtKB:Q04401}.
CC   -!- SIMILARITY: Belongs to the complex I LYR family. SDHAF3 subfamily.
CC       {ECO:0000305}.
