Protein function (UniProt)

NADH dehydrogenase [ubiquinone] iron-sulfur protein 4, mitochondrial

Accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), that is believed not to be involved in catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone
