NADH dehydrogenase [ubiquinone] 1 alpha subcomplex subunit 1 (NDUFA1)

Accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), that's believed to not participate in catalysis. Complex I functions in the transport of electrons from NADH to the respiratory chain.

The immediate electron acceptor for the enzyme is believed to be ubiquinone. .
