protein bindingmolecular functionBinding to a protein. [GOC:go_curators]
NADH dehydrogenase (ubiquinone) activitymolecular functionCatalysis of the reaction: NADH + ubiquinone + 5 H+(in) = NAD+ + ubiquinol + 4 H+(out). [RHEA:29091]
protein-containing complex bindingmolecular functionBinding to a macromolecular complex. [GOC:jl]

Located In

This protein is located in 3 target(s):

TargetCategoryDefinition
mitochondrioncellular componentA 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 membranecellular componentThe inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae. [GOC:ai]
mitochondrial membranecellular componentEither of the lipid bilayers that surround the mitochondrion and form the mitochondrial envelope. [GOC:mah, NIF_Subcellular:sao1045389829]

Part Of

This protein is part of 2 target(s):

TargetCategoryDefinition
mitochondrial respiratory chain complex IVcellular componentA protein complex located in the mitochondrial inner membrane that forms part of the mitochondrial respiratory chain. Contains the 13 polypeptide subunits of cytochrome c oxidase, including cytochrome a and cytochrome a3. Catalyzes the oxidation of reduced cytochrome c by dioxygen (O2). [GOC:mtg_sensu, ISBN:0198547684]
mitochondrial respiratory chain complex Icellular componentA 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 5 target(s):

TargetCategoryDefinition
mitochondrial electron transport, NADH to ubiquinonebiological processThe transfer of electrons from NADH to ubiquinone that occurs during oxidative phosphorylation. [ISBN:0716731363]
mitochondrial electron transport, cytochrome c to oxygenbiological processThe transfer of electrons from cytochrome c to oxygen that occurs during oxidative phosphorylation, mediated by the multisubunit enzyme known as complex IV. [ISBN:0716731363]
cellular respirationbiological processThe 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]
transmembrane transportbiological processThe process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other. [GOC:dph, GOC:jid]
positive regulation of cytochrome-c oxidase activitybiological processAny process that activates or increases the frequency, rate or extent of cytochrome-c oxidase activity. [GO_REF:0000059, GOC:TermGenie, PMID:26734017]
