Summaries
Gene Group (FlyBase)
MITOCHONDRIAL COMPLEX I - NADH:UBIQUINONE OXIDOREDUCTASE COMPLEX SUBUNITS -
The NADH:ubiquinone oxidoreductase complex (Mitochondrial Complex I) is the first enzyme of the mitochondrial electron transport chain. It oxidizes NADH from the tricarboxylic acid cycle and β oxidation of fatty acids, reduces ubiquinone and transports protons across the inner membrane, contributing to the proton-motive force. It is also involved in the cellular production of reactive oxygen species. (Adapted from PMID:23527692).
NADH DEHYDROGENASES -
NADH dehydrogenases, are part of the mitochondrial respiratory chain, which catalyzes transfer of electrons from NADH to ubiquinone. (Adapted from PMID:21822288).
Protein Function (UniProtKB)
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).

              New annotation (CG34063) in release 4.3 of the genome annotation.
              mt:ND2 has been cloned and sequenced, and compared to Dsim\mt:ND2, Dsec\mt:ND2 and Dmau\mt:ND2.
              During oogenesis RNA from mt:srRNA, mt:lrRNA, mt:ND2, mt:CoI, mt:CoII, mt:CoIII, mt:ND4, mt:ND5 and mt:Cyt-b shows fluctuations in RNA density after stage 9 in follicle and nurse cells.There is a correlation between the mtRNA level and the cell volume and/or the nuclear DNA content suggesting a global extra-mitochondrial, transcriptional control mechanism.
