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 Peripheral membrane protein {ECO:0000250}; Matrix side {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the complex I NDUFB2 subunit family.
CC {ECO:0000305}.
