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 + NADH + 5 H(+)(in) = a ubiquinol + NAD(+) + 4 CC H(+)(out); 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: Mitochondrion inner membrane CC {ECO:0000256|ARBA:ARBA00004448, ECO:0000256|RuleBase:RU003403}; Multi- CC pass membrane protein {ECO:0000256|ARBA:ARBA00004448, CC ECO:0000256|RuleBase:RU003403}. CC -!- SIMILARITY: Belongs to the complex I subunit 2 family. CC {ECO:0000256|ARBA:ARBA00007012, ECO:0000256|RuleBase:RU003403}.
