"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). COFACTOR: Binds 1 FAD per dimer. SUBUNIT: Heterodimer of an alpha and a beta subunit. SUBCELLULAR LOCATION: Mitochondrion matrix. ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=2; Name=1; IsoId=P13804-1; Sequence=Displayed; Name=2; IsoId=P13804-2; Sequence=VSP_043246; Note=No experimental confirmation available; PTM: The N-terminus is blocked. DISEASE: Defects in ETFA are the cause of glutaric aciduria type 2A (GA2A) [MIM:231680]; also known as glutaricaciduria IIA. GA2A is an autosomal recessively inherited disorder of fatty acid, amino acid, and choline metabolism. It is characterized by multiple acyl-CoA dehydrogenase deficiencies resulting in large excretion not only of glutaric acid, but also of lactic, ethylmalonic, butyric, isobutyric, 2-methyl-butyric, and isovaleric acids. SIMILARITY: Belongs to the ETF alpha-subunit/fixB family. WEB RESOURCE: Name=GeneReviews; URL=\"http://www.ncbi.nlm.nih.gov/sites/GeneTests/lab/gene/ETFA\"; GENE SYNONYMS:ETFA.
