NADH-ubiquinone oxidoreductase 75 kDa subunit, mitochondrial

UniProtKB accession:  Q91VD9

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) which catalyzes electron transfer from NADH through the respiratory chain, using ubiquinone as an electron acceptor (PubMed:27799543, PubMed:32072193, PubMed:38575788). Essential for catalysing the entry and efficient transfer of electrons within complex I (PubMed:27799543). Plays a key role in the assembly and stability of complex I and participates in the association of complex I with ubiquinol-cytochrome reductase complex (Complex III) to form supercomplexes (PubMed:27799543).
