Protein: Electron transfer flavoprotein subunit alpha (A0A8I5KYH4)
Organism: Homo sapiens (Human)
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)
Subcellular location: Mitochondrion matrix
