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 (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Complex I is composed of at least 49 different subunits.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC       Single-pass membrane protein {ECO:0000250}; Matrix side {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the complex I NDUFB3 subunit family.
CC       {ECO:0000305}.
