Function

Heterodimeric electron transfer flavoprotein that accepts electrons from several mitochondrial dehydrogenases, including acyl-CoA dehydrogenases, glutaryl-CoA and sarcosine dehydrogenase (PubMed:10356313, PubMed:15159392, PubMed:15975918, PubMed:27499296, PubMed:9334218). It transfers the electrons to the main mitochondrial respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase) (PubMed:9334218). Required for normal mitochondrial fatty acid oxidation and normal amino acid metabolism (PubMed:12815589, PubMed:1430199, PubMed:1882842).

Activity summary

ETFA or Electron-Transfer-Flavoprotein alpha subunit is an essential part of the mitochondrial respiratory chain. This protein which has a molecular mass of approximately 34 kDa functions in the transfer of electrons from acyl-CoA dehydrogenases to the main respiratory chain for energy production. ETFA is commonly expressed in tissues with high-energy demands such as the liver heart and skeletal muscle. The protein forms a heterodimeric complex with its counterpart ETFB providing a critical function in electron transfer during fatty acid oxidation.

Biological function summary

ETFA operates as an important part of the electron transfer process within the mitochondria. It acts as one-half of the heterodimeric electron-transfer flavoprotein complex teaming with ETFB. This complex facilitates electron transfer from a range of acyl-CoA dehydrogenases to ETF dehydrogenase which then continues the process of electron transfer to coenzyme Q in the respiratory chain. This action is key to the breakdown of fats enabling energy extraction and processing.

Pathways

ETFA has important roles in fatty acid beta-oxidation and amino acid catabolism. It engages in these pathways by transferring electrons as mentioned interfacing with other proteins like ETF dehydrogenase. This positioning within the mitochondrial matrix enables ETFA to assist in converting fat and protein substrates into energy which the cell can use. Its molecular interactions highlight its integral position in maintaining energy homeostasis.

Associated diseases and disorders

Problems with ETFA lead to glutaric acidemia type 2 a metabolic disorder that impairs the body's ability to oxidize fatty acids and some amino acids. Deficiencies in ETFA function disrupt the electron transport to the respiratory chain causing an accumulation of intermediary metabolites. These disruptions can relate to or involve other mitochondrial components and proteins like ETFB or ETFDH. Correct diagnosis and understanding of ETFA’s role in such conditions are instrumental for targeted therapeutic approaches.

    Overlay histogram showing HeLa cells stained with ab198303 (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 (ab198303, 1/50 dilution) for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2b (monoclonal) Alexa Fluor® 488 (ab171465) used at the same concentration and conditions as the primary antibody. 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.

The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab198303 at 1/100 dilution (shown in green) and Alexa Fluor® 594 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker ab195889, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 594), at 1/250 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).

    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

    This product also gave a positive signal under the same testing conditions in HeLa cells fixed with 100% methanol (5min).
