背景信息

NDUFAF1 (NADH:ubiquinone oxidoreductase complex assembly factor 1) is a nuclear-encoded protein critical for the assembly and function of mitochondrial respiratory chain Complex I (CI), the largest enzyme complex in the electron transport chain. CI, also known as NADH dehydrogenase, plays a central role in oxidative phosphorylation by catalyzing electron transfer from NADH to ubiquinone, coupled with proton translocation across the mitochondrial inner membrane. Defects in CI assembly or function are linked to severe mitochondrial disorders, including Leigh syndrome and cardiomyopathy.

NDUFAF1 is localized to the mitochondrial matrix and interacts with CI subunits during early assembly stages. It acts as a chaperone-like protein, facilitating the incorporation of specific subcomplexes into the mature CI structure. Mutations in the NDUFAF1 gene disrupt this process, leading to CI deficiency, impaired ATP production, and increased oxidative stress. These cellular dysfunctions manifest clinically as energy-deficient tissues, particularly affecting the brain, heart, and skeletal muscles.

Recombinant NDUFAF1 protein is produced using heterologous expression systems (e.g., E. coli or mammalian cell cultures) for structural and functional studies. Researchers employ it to investigate CI assembly mechanisms, model mitochondrial diseases, and screen potential therapeutic compounds. Its purified form enables in vitro reconstitution experiments to dissect protein-protein interactions within CI assembly pathways. Additionally, recombinant NDUFAF1 serves as an antigen for antibody production in diagnostic assays detecting CI-related disorders. Recent studies also explore its potential in gene therapy approaches, where functional NDUFAF1 delivery could rescue CI defects in patient-derived cells. However, challenges remain in achieving proper mitochondrial targeting and sustained expression of the recombinant protein in therapeutic contexts.
