  • 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.
  • Involvement in disease
    Defects in NDUFS4 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 NDUFS4 subunit family.
  • Cellular localization
    Mitochondrion inner membrane.

  • Predicted band size : 20 kDa

    Lane 1: Wild-type HAP1 cell lysate (20 µg)
    Lane 2: Ndufs4knockout HAP1 cell lysate (20 µg)
    Lane 3: HEK293 cell lysate (20 µg)
    Lane 4: Hu fetal heart tissue lysate (20 µg)
    Lanes 1 - 4: Merged signal (red and green). Green - ab55540 observed at 28 kDa. Red - loading control, ab181602, observed at 37 kDa.

    ab55540 was shown to recognize Ndufs4 when Ndufs4 knockout samples were used, along with additional cross-reactive bands. Wild-type and Ndufs4 knockout samples were subjected to SDS-PAGE. ab55540 and ab181602 (loading control to GAPDH) at a concentration of 1 µg/ml and a dilution of 1/10000 and incubated overnight at 4°C. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed (ab216772) and Goat Anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed (ab216777) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
