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:Q16795}.
CC   -!- COFACTOR:
CC       Name=FAD; Xref=ChEBI:CHEBI:57692; Evidence={ECO:0000250};
CC       Note=Binds 1 FAD per subunit. {ECO:0000250};
CC   -!- SUBUNIT: Complex I is composed of 45 different subunits (By
CC       similarity). This a component of the hydrophobic protein fraction (By
CC       similarity). Interacts with BLOC1S1 (By similarity). Interacts with
CC       SLC2A4 (By similarity). Interacts with CLOCK (By similarity). Interacts
CC       with RAB5IF (By similarity). {ECO:0000250|UniProtKB:Q16795,
CC       ECO:0000250|UniProtKB:Q5BK63}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC       {ECO:0000250|UniProtKB:Q16795}.
CC   -!- PTM: Acetylated on lysine residues. BLOC1S1 is required for
CC       acetylation. Acetylated by CLOCK in a circadian manner.
CC       {ECO:0000250|UniProtKB:Q16795}.
CC   -!- SIMILARITY: Belongs to the complex I NDUFA9 subunit family.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=ABH12231.1; Type=Erroneous initiation; Evidence={ECO:0000305};
