  • Function
    The electron transfer flavoprotein serves as a specific electron acceptor for several dehydrogenases, including five acyl-CoA dehydrogenases, glutaryl-CoA and sarcosine dehydrogenase. It transfers the electrons to the main mitochondrial respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase).
  • Involvement in disease
    Glutaric aciduria 2A
  • Sequence similarities
    Belongs to the ETF alpha-subunit/FixB family.
  • Domain
    Domain I shares an identical polypeptide fold with the beta subunit ETFB though there is no sequence similarity.
  • Post-translational
    The N-terminus is blocked.
  • Cellular localization
    Mitochondrion matrix.

  • Immunocytochemistry image of stained HeLa cells. The cells were paraformaldehyde fixed (4%, 20 minutes) and Triton X-100 permeabilized (0.1%, 15 minutes). The cells were incubated with the antibody (ab110316, 4 µg/mL) for 2 hours at room temperature or over night at 4°C. The secondary antibody was (red) Alexa Fluor® 594 goat anti-mouse IgG (H+L) at a 1/1000 dilution for 1 hour. 10% Goat serum was used as the blocking agent for all blocking steps. The target protein locates to the mitochondrial matrix

  • HL-60 cells were stained with 1 µg/mL ab110316 (blue) or an equal amount of an isotype control antibody (red) and analyzed by flow cytometry.
  • IHC image of ETFA staining in Human heart formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab110316, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
