  • FunctionPlays a role in intermediary metabolism and energy production. It may tightly associate or interact with the pyruvate dehydrogenase complex.
  • Involvement in diseaseD-2-hydroxyglutaric aciduria 2
    enetic variations are associated with cartilaginous tumors such as enchondroma or chondrosarcoma.
  • Sequence similaritiesBelongs to the isocitrate and isopropylmalate dehydrogenases family.
  • Post-translational
    Acetylation at Lys-413 dramatically reduces catalytic activity. Deacetylated by SIRT3.

  • Predicted band size : 51 kDa

    Lane 1: Wild-type HAP1 cell lysate (20 µg)
    Lane 2: IDH2 knockout HAP1 cell lysate (20 µg)
    Lane 3: K562 cell lysate (20 µg)
    Lane 4: HepG2 cell lysate (20 µg)
    Lanes 1 - 4: Merged signal (red and green). Green - ab94359 observed at 47 kDa. Red - loading control, ab8245, observed at 37 kDa.

    ab94359 was shown to recognize IDH2 when IDH2 knockout samples were used, along with additional cross-reactive bands. Wild-type and IDH2 knockout samples were subjected to SDS-PAGE. ab94359 at a concentration of 1ug/ml and ab8245 (loading control to GAPDH) diluted to 1/2000 and incubated overnight at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

    Performed under reducing conditions.

    Predicted band size : 51 kDa
    Observed band size : 47 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 35 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 30 seconds
    The predicted molecular weight of the IDH2 protein is 51-kDa. However, the protein sequence contains a 39 residue transit peptide at the N-terminus. This might explain the migration of the protein at a lower molecular weight than expected.
  • ICC/IF image of ab94359 stained HepG2 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab94359, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 100% methanol fixed (5 min) MCF7 cells at 1µg/ml, and in 4% PFA fixed (10 min) HepG2 cells at 1µg/ml.
