  • 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.
  • Involvement in disease

    Defects in NDUFS2 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.
  • Sequence similarities

    Belongs to the complex I 49 kDa subunit family.
  • Cellular localization

    Mitochondrion inner membrane.

  • Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
    Lane 2: NDUFS2 knockout HAP1 whole cell lysate (20 µg)
    Lane 3: HeLa whole cell lysate (20 µg)
    Lane 4: Jurkat whole cell lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab110249 observed at 48 kDa. Red - loading control, ab181602, observed at 37 kDa.

    ab110249 was shown to specifically react with NDUFS2 in wild-type HAP1 cells whilst signal was lost in NDUFS2 knockout cells. Wild-type and NDUFS2 knockout samples were subjected to SDS-PAGE. ab110249 and ab181602 (Rabbit anti-GAPDH loading control) were incubated overnight at 4°C at 0.25 µg/ml and 1/20,000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed (ab216772) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed (ab216777) secondary antibodies at 1/20,000 dilution for 1 hour at room temperature before imaging.

  • Overlay histogram showing HepG2 cells stained with ab110249 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab110249, 1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-mouse IgG (H&L) (ab150113) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
