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. Required for flavinylation (covalent
CC       attachment of FAD) of the flavoprotein subunit of the SDH catalytic
CC       dimer. {ECO:0000255|HAMAP-Rule:MF_03057}.
CC   -!- SUBUNIT: Interacts with the flavoprotein subunit within the SDH
CC       catalytic dimer. {ECO:0000255|HAMAP-Rule:MF_03057}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000255|HAMAP-
CC       Rule:MF_03057}.
CC   -!- SIMILARITY: Belongs to the SDHAF2 family. {ECO:0000255|HAMAP-
CC       Rule:MF_03057}.
