ID:NDUV2_HUMAN DESCRIPTION: RecName: Full=NADH dehydrogenase [ubiquinone] flavoprotein 2, mitochondrial; EC=1.6.5.3; EC=1.6.99.3; AltName: Full=NADH-ubiquinone oxidoreductase 24 kDa subunit; 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). CATALYTIC ACTIVITY: NADH + ubiquinone = NAD(+) + ubiquinol. CATALYTIC ACTIVITY: NADH + acceptor = NAD(+) + reduced acceptor. COFACTOR: Binds 1 2Fe-2S cluster (Potential). SUBUNIT: Complex I is composed of 45 different subunits. This is a component of the flavoprotein-sulfur (FP) fragment of the enzyme. SUBCELLULAR LOCATION: Mitochondrion inner membrane. SIMILARITY: Belongs to the complex I 24 kDa subunit family.
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.
