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. Essential for the catalytic activity of complex I.
CC {ECO:0000250|UniProtKB:P03897}.
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:P03897};
CC -!- SUBUNIT: Core subunit of respiratory chain NADH dehydrogenase (Complex
CC I) which is composed of 45 different subunits. Interacts with TMEM186.
CC Interacts with TMEM242 (By similarity). {ECO:0000250|UniProtKB:P03897}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000250|UniProtKB:P03898}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the complex I subunit 3 family. {ECO:0000305}.
