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 catalysing the entry and
CC efficient transfer of electrons within complex I (By similarity). Plays
CC a key role in the assembly and stability of complex I and participates
CC in the association of complex I with ubiquinol-cytochrome reductase
CC complex (Complex III) to form supercomplexes (By similarity).
CC {ECO:0000250|UniProtKB:P28331}.
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 Note=Binds 2 [4Fe-4S] clusters per subunit.
CC {ECO:0000250|UniProtKB:Q56223};
CC -!- SUBUNIT: Core subunit of respiratory chain NADH dehydrogenase (Complex
CC I) which is composed of 45 different subunits (By similarity). This is
CC the largest subunit of complex I and it is a component of the iron-
CC sulfur (IP) fragment of the enzyme (By similarity). Complex I
CC associates with ubiquinol-cytochrome reductase complex (Complex III) to
CC form supercomplexes (By similarity). Interacts with MDM2 and AKAP1 (By
CC similarity). {ECO:0000250|UniProtKB:P15690,
CC ECO:0000250|UniProtKB:P28331, ECO:0000250|UniProtKB:Q91VD9}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000250|UniProtKB:P15690}; Peripheral membrane protein
CC {ECO:0000250|UniProtKB:P15690}; Matrix side
CC {ECO:0000250|UniProtKB:P15690}.
CC -!- SIMILARITY: Belongs to the complex I 75 kDa subunit family.
CC {ECO:0000305}.
