NDUFS7 Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for 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. Belongs to the complex I 20 kDa subunit family. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
