Enables

This protein enables 6 target(s):

Target	Category	Definition
protein binding	molecular function	Binding to a protein. [GOC:go_curators]
NADH dehydrogenase (ubiquinone) activity	molecular function	Catalysis of the reaction: NADH + ubiquinone + 5 H+(in) = NAD+ + ubiquinol + 4 H+(out). [RHEA:29091]
electron transfer activity	molecular function	A molecular function representing the directed movement of electrons from one molecular entity to another, typically mediated by electron carriers or acceptors, resulting in the transfer of energy and/or the reduction-oxidation (redox) transformation of chemical species. This activity is fundamental to various biological processes, including cellular respiration and photosynthesis, as well as numerous enzymatic reactions involved in metabolic pathways. [Wikipedia:Electron_transfer]
metal ion binding	molecular function	Binding to a metal ion. [GOC:ai]
2 iron, 2 sulfur cluster binding	molecular function	Binding to a 2 iron, 2 sulfur (2Fe-2S) cluster; this cluster consists of two iron atoms, with two inorganic sulfur atoms found between the irons and acting as bridging ligands. [GOC:ai, PMID:15952888, Wikipedia:Iron-sulfur_cluster]
4 iron, 4 sulfur cluster binding	molecular function	Binding to a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands. [GOC:ai, PMID:15952888, Wikipedia:Iron-sulfur_cluster]

Located In

This protein is located in 4 target(s):

Target	Category	Definition
mitochondrion	cellular component	A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration. [GOC:giardia, ISBN:0198506732]
mitochondrial inner membrane	cellular component	The inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae. [GOC:ai]
mitochondrial intermembrane space	cellular component	The region between the inner and outer lipid bilayers of the mitochondrial envelope. [GOC:mah]
mitochondrial matrix	cellular component	The gel-like material, with considerable fine structure, that lies in the matrix space, or lumen, of a mitochondrion. It contains the enzymes of the tricarboxylic acid cycle and, in some organisms, the enzymes concerned with fatty acid oxidation. [GOC:as, ISBN:0198506732]

Part Of

This protein is part of 1 target(s):

Target	Category	Definition
mitochondrial respiratory chain complex I	cellular component	A protein complex located in the mitochondrial inner membrane that forms part of the mitochondrial respiratory chain. It contains about 25 different polypeptide subunits, including NADH dehydrogenase (ubiquinone), flavin mononucleotide and several different iron-sulfur clusters containing non-heme iron. The iron undergoes oxidation-reduction between Fe(II) and Fe(III), and catalyzes proton translocation linked to the oxidation of NADH by ubiquinone. [GOC:mtg_sensu, ISBN:0198547684]

Involved In

This protein is involved in 10 target(s):

Target	Category	Definition
mitochondrial electron transport, NADH to ubiquinone	biological process	The transfer of electrons from NADH to ubiquinone that occurs during oxidative phosphorylation. [ISBN:0716731363]
apoptotic mitochondrial changes	biological process	The morphological and physiological alterations undergone by mitochondria during apoptosis. [GOC:mah, GOC:mtg_apoptosis]
aerobic respiration	biological process	The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which requires oxygen as the terminal electron acceptor. [GOC:das, GOC:jl, ISBN:0140513590]
mitochondrial respiratory chain complex I assembly	biological process	The aggregation, arrangement and bonding together of a set of components to form mitochondrial respiratory chain complex I. [GOC:rph]
proton motive force-driven mitochondrial ATP synthesis	biological process	The transport of protons across a mitochondrial membrane to generate an electrochemical gradient (proton-motive force) that powers ATP synthesis. [GOC:mtg_sensu, ISBN:0716731363]
cellular respiration	biological process	The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which either requires oxygen (aerobic respiration) or does not (anaerobic respiration). [GOC:das, ISBN:0140513590, ISBN:0198506732]
ATP metabolic process	biological process	The chemical reactions and pathways involving ATP, adenosine triphosphate, a universally important coenzyme and enzyme regulator. [GOC:go_curators]
regulation of mitochondrial membrane potential	biological process	Any process that modulates the establishment or extent of the mitochondrial membrane potential, the electric potential existing across the mitochondrial membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. [GOC:ai]
transmembrane transport	biological process	The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other. [GOC:dph, GOC:jid]
reactive oxygen species metabolic process	biological process	The chemical reactions and pathways involving a reactive oxygen species, any molecules or ions formed by the incomplete one-electron reduction of oxygen. They contribute to the microbicidal activity of phagocytes, regulation of signal transduction and gene expression, and the oxidative damage to biopolymers. [GOC:mah]
