ETFA participates in catalyzing the initial step of the mitochondrial fatty acid beta-oxidation. It shuttles electrons between primary flavoprotein dehydrogenases and the membrane-bound electron transfer flavoprotein ubiquinone oxidoreductase. Defects in electron-transfer-flavoprotein have been implicated in type II glutaricaciduria in which multiple acyl-CoA dehydrogenase deficiencies result in large excretion of glutaric, lactic, ethylmalonic, butyric, isobutyric, 2-methyl-butyric, and isovaleric acids. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
A study in humans demonstrated that the ETFA was downregulated in the adipose tissue of heavier co-twins within BMI-discordant monozygotic twin pairs, indicating its involvement in mitochondrial metabolism in acquired obesity [van der Kolk et al. DOI:10.1016/j.xcrm.2021.100226]. In a separate human study, the ETFA was identified as a single-gene blood biomarker capable of differentiating methamphetamine dependents without psychosis from those with methamphetamine-associated psychosis [Breen et al. DOI:10.1038/tp.2016.67].
