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:0000256|PIRNR:PIRNR009288}.
CC -!- SUBUNIT: Complex I is composed of 45 different subunits.
CC {ECO:0000256|ARBA:ARBA00011533, ECO:0000256|PIRNR:PIRNR009288}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000256|ARBA:ARBA00004298}; Single-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004298}; Matrix side
CC {ECO:0000256|ARBA:ARBA00004298}.
CC -!- SIMILARITY: Belongs to the complex I NDUFB8 subunit family.
CC {ECO:0000256|ARBA:ARBA00008039, ECO:0000256|PIRNR:PIRNR009288}.
