Application Abreviews Notes
  • Application notes
    ELISA: Use at an assay dependent dilution.
    WB: Use at an assay dependent concentration. Predicted molecular weight: 28 kDa.

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function

      NAD-dependent protein deacetylase. Activates or deactivates mitochondrial target proteins by deacetylating key lysine residues. Known targets include ACSS1, IDH, GDH, SOD2, PDHA1, LCAD, SDHA and the ATP synthase subunit ATP5O. Contributes to the regulation of the cellular energy metabolism. Important for regulating tissue-specific ATP levels.
    • Tissue specificity

      Widely expressed.
    • Sequence similarities

      Belongs to the sirtuin family. Class I subfamily.
      Contains 1 deacetylase sirtuin-type domain.
    • Post-translational

      Processed by mitochondrial processing peptidase (MPP) to give a 28 kDa product. Such processing is probably essential for its enzymatic activity.
    • Cellular localization

      Mitochondrion matrix.

    • Anti-SIRT3 antibody (ab56214) at 1 µg/ml + Liver (Mouse) Tissue Lysate at 10 µg

      Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution

      Developed using the ECL technique.

      Performed under reducing conditions.

      Predicted band size: 44 kDa
      Observed band size: 48 kDa
      why is the actual band size different from the predicted?
      Additional bands at: 12 kDa, 35 kDa. We are unsure as to the identity of these extra bands.

      Exposure time: 20 minutes

      The 48 kDa band observed is comparable to the molecular weight seen with other commercially available antibodies to SIRT3.
