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:O75438}.
CC   -!- SUBUNIT: Complex I is composed of 45 different subunits.
CC       {ECO:0000250|UniProtKB:O75438}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC       {ECO:0000250|UniProtKB:O75438}; Single-pass membrane protein
CC       {ECO:0000255}; Matrix side {ECO:0000250|UniProtKB:O75438}.
CC   -!- SIMILARITY: Belongs to the complex I NDUFB1 subunit family.
CC       {ECO:0000305}.
