ID:NDUS1_HUMAN DESCRIPTION: RecName: Full=NADH-ubiquinone oxidoreductase 75 kDa subunit, mitochondrial; EC=1.6.5.3; EC=1.6.99.3; AltName: Full=Complex I-75kD; Short=CI-75kD; Flags: Precursor; FUNCTION: Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for 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 (By similarity). This is the largest subunit of complex I and it is a component of the iron-sulfur (IP) fragment of the enzyme. It may form part of the active site crevice where NADH is oxidized. CATALYTIC ACTIVITY: NADH + ubiquinone = NAD(+) + ubiquinol. CATALYTIC ACTIVITY: NADH + acceptor = NAD(+) + reduced acceptor. COFACTOR: Binds 1 2Fe-2S cluster per subunit (By similarity). COFACTOR: Binds 2 4Fe-4S clusters per subunit (By similarity). SUBUNIT: Complex I is composed of 45 different subunits. SUBCELLULAR LOCATION: Mitochondrion inner membrane. DISEASE: Defects in NDUFS1 are a cause of mitochondrial complex I deficiency (MT-C1D) [MIM:252010]. A disorder of the mitochondrial respiratory chain that causes a wide range of clinical disorders, 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. SIMILARITY: Belongs to the complex I 75 kDa subunit family. SIMILARITY: Contains 1 2Fe-2S ferredoxin-type domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
