The recombinant human NDUFA7 protein is a key component of mitochondrial Complex I (NADH:ubiquinone oxidoreductase), the first enzyme in the electron transport chain responsible for oxidative phosphorylation. As part of the NADH dehydrogenase (ubiquinone) complex, NDUFA7 is one of approximately 45 subunits that form the functional assembly of Complex I, which transfers electrons from NADH to ubiquinone while pumping protons across the mitochondrial inner membrane to generate ATP. Specifically, NDUFA7 is categorized as an accessory subunit within the membrane-bound fraction of Complex I, contributing to structural stability or regulatory functions, though its precise mechanistic role remains under investigation.
Genetic mutations in the NDUFA7 gene have been linked to mitochondrial disorders, such as Leigh syndrome and other neurodegenerative or metabolic diseases associated with impaired energy production. Recombinant NDUFA7 protein, typically expressed in prokaryotic or eukaryotic systems like *E. coli* or mammalian cell lines, enables researchers to study its biochemical properties, interaction partners, and pathogenic variants in vitro. Its production facilitates functional assays, antibody development, and therapeutic exploration for mitochondrial dysfunctions.
Studies using recombinant NDUFA7 also contribute to understanding Complex I assembly mechanisms and its role in reactive oxygen species (ROS) regulation, providing insights into aging, neurodegeneration, and cancer. Continued research on this protein may advance diagnostic tools and targeted therapies for mitochondrial-related pathologies.
