NADH:ubiquinone oxidoreductase complex assembly factor 5 (NDUFAF5) is a protein that plays a crucial role in the mitochondrial respiratory chain, specifically in the assembly and stabilization of complex I, also known as NADH:ubiquinone oxidoreductase. Complex I is the largest and first enzyme complex in the mitochondrial electron transport chain (ETC), which is vital for the process of oxidative phosphorylation, the primary method by which eukaryotic cells generate ATP.NDUFAF5 functions as an assembly factor, meaning that it helps in the proper formation and maintenance of the complex I structure. It is involved in the early stages of complex I assembly, facilitating the incorporation of various subunits into the nascent complex. Without the action of NDUFAF5 and other assembly factors, complex I would not form correctly, leading to potential deficits in energy production.

The importance of NDUFAF5 is underscored by its association with mitochondrial diseases. Mutations in the gene encoding NDUFAF5 have been linked to mitochondrial complex I deficiency, which is a heterogeneous group of disorders characterized by a reduction in complex I activity. This can result in neurodegenerative diseases, muscle weakness, and metabolic dysregulation, highlighting the protein's essential role in cellular metabolism and energy homeostasis.Structurally, NDUFAF5 contains domains that likely mediate interactions with other proteins, specifically the subunits of complex I. These interactions are critical for the stepwise assembly of the complex, ensuring that each subunit is correctly positioned and that the enzyme complex achieves its proper conformation and function.
