CC   -!- FUNCTION: Accessory subunit of the mitochondrial membrane respiratory
CC       chain NADH dehydrogenase (Complex I), that is believed not to be
CC       involved in catalysis. Complex I functions in the transfer of electrons
CC       from NADH to the respiratory chain. The immediate electron acceptor for
CC       the enzyme is believed to be ubiquinone.
CC       {ECO:0000250|UniProtKB:O43181}.
CC   -!- SUBUNIT: Mammalian complex I is composed of 45 different subunits. This
CC       is a component of the iron-sulfur (IP) fragment of the enzyme.
CC       Interacts with BCAP31 and TOMM40; the interaction mediates its
CC       translocation to the mitochondria; the interaction with BCAP31 is
CC       direct. {ECO:0000250|UniProtKB:O43181}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC       {ECO:0000250|UniProtKB:O43181}; Peripheral membrane protein
CC       {ECO:0000250|UniProtKB:O43181}; Matrix side
CC       {ECO:0000250|UniProtKB:O43181}. Note=The interaction with BCAP31
CC       mediates mitochondria localization. {ECO:0000250|UniProtKB:O43181}.
CC   -!- SIMILARITY: Belongs to the complex I NDUFS4 subunit family.
CC       {ECO:0000305}.
