CC   -!- FUNCTION: Core subunit of the mitochondrial membrane respiratory chain
CC       NADH dehydrogenase (Complex I) which catalyzes electron transfer from
CC       NADH through the respiratory chain, using ubiquinone as an electron
CC       acceptor (By similarity). Essential for the catalytic activity and
CC       assembly of complex I (By similarity). {ECO:0000250|UniProtKB:O75489}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a ubiquinone + 5 H(+)(in) + NADH = a ubiquinol + 4 H(+)(out) +
CC         NAD(+); Xref=Rhea:RHEA:29091, Rhea:RHEA-COMP:9565, Rhea:RHEA-

CC         ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=7.1.1.2;
CC         Evidence={ECO:0000250|UniProtKB:O75489};
CC   -!- SUBUNIT: Core subunit of respiratory chain NADH dehydrogenase (Complex
CC       I) which is composed of 45 different subunits (By similarity).
CC       Interacts with NDUFAF3 (By similarity). Interacts with RAB5IF (By
CC       similarity). Found in subcomplexes containing subunits NDUFS2, MT-ND1
CC       and NDUFA13 (By similarity). {ECO:0000250|UniProtKB:O75489}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC       {ECO:0000250|UniProtKB:O75489}; Peripheral membrane protein
CC       {ECO:0000250|UniProtKB:O75489}; Matrix side
CC       {ECO:0000250|UniProtKB:O75489}.
CC   -!- SIMILARITY: Belongs to the complex I 30 kDa subunit family.
CC       {ECO:0000305}.
