UniProtKB - P15690 (NDUS1_BOVIN)
NADH-ubiquinone oxidoreductase 75 kDa subunit, mitochondrial
NDUFS1
Functioni
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:10852722, PubMed:18721790).
Essential for catalysing the entry and efficient transfer of electrons within complex I (By similarity).
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 (By similarity).

Subunit structurei
Core subunit of respiratory chain NADH dehydrogenase (Complex I) which is composed of 45 different subunits (PubMed:10852722, PubMed:18721790, PubMed:25209663). This is the largest subunit of complex I and it is a component of the iron-sulfur (IP) fragment of the enzyme (PubMed:10852722, PubMed:25209663). Complex I associates with ubiquinol-cytochrome reductase complex (Complex III) to form supercomplexes (By similarity).
Interacts with MDM2 and AKAP1 (By similarity).
