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 and assembly of complex CC I. {ECO:0000256|RuleBase:RU003403}. 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 Evidence={ECO:0000256|ARBA:ARBA00000766, CC ECO:0000256|RuleBase:RU003403}; CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi- CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}. Mitochondrion CC inner membrane {ECO:0000256|ARBA:ARBA00004448, CC ECO:0000256|RuleBase:RU003403}; Multi-pass membrane protein CC {ECO:0000256|ARBA:ARBA00004448, ECO:0000256|RuleBase:RU003403}. CC -!- SIMILARITY: Belongs to the complex I subunit 2 family. CC {ECO:0000256|ARBA:ARBA00007012, ECO:0000256|RuleBase:RU003403}.
