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. {ECO:0000250|UniProtKB:P03902}.
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         COMP:9566, ChEBI:CHEBI:15378, ChEBI:CHEBI:16389, ChEBI:CHEBI:17976,
CC         ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=7.1.1.2;
CC   -!- SUBUNIT: Core subunit of respiratory chain NADH dehydrogenase (Complex
CC       I) which is composed of 45 different subunits.
CC       {ECO:0000250|UniProtKB:P03902}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC       {ECO:0000250|UniProtKB:P03902}; Multi-pass membrane protein
CC       {ECO:0000255}.
CC   -!- SIMILARITY: Belongs to the complex I subunit 4L family. {ECO:0000305}.
