Gene Symbol NDUFS4
Protein Name NADH dehydrogenase (ubiquinone) Fe-S protein 4, 18kDa (NADH-coenzyme Q reductase)
Synonyms AQDQ; CI-18;
Species Homo sapiens
Ensembl Protein ENSP00000296684
InnateDB Gene IDBG-20547 (NDUFS4)
Protein Structure
UniProt Annotation
Function Accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), that is believed not to be involved in catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone.
Subcellular Localization Mitochondrion inner membrane; Peripheral membrane protein; Matrix side.
Disease Associations Mitochondrial complex I deficiency (MT-C1D) [MIM:252010]: A disorder of the mitochondrial respiratory chain that causes a wide range of clinical manifestations from lethal neonatal disease to adult-onset neurodegenerative disorders. Phenotypes include macrocephaly with progressive leukodystrophy, non-specific encephalopathy, cardiomyopathy, myopathy, liver disease, Leigh syndrome, Leber hereditary optic neuropathy, and some forms of Parkinson disease. Note=The disease is caused by mutations affecting the gene represented in this entry.
