NADH:ubiquinone oxidoreductase complex assembly factor 5, also known as NDUFAF5, is a protein that in humans is encoded by the NDUFAF5 gene. This protein is an assembly factor involved in the maturation and assembly of Complex I of the mitochondrial respiratory chain, which is also known as NADH:ubiquinone oxidoreductase. Complex I is the largest of the five complexes that comprise the electron transport chain, a crucial part of oxidative phosphorylation, and is responsible for the initial transfer of electrons from NADH to ubiquinone.

The role of NDUFAF5 is particularly important as it assists in the correct formation and stabilization of Complex I, which consists of over 40 different subunits. The process of assembling these subunits is intricate and highly coordinated, requiring several assembly factors, like NDUFAF5, to ensure proper assembly and function of the complex. NDUFAF5 is believed to participate in the early stages of the Complex I assembly process, where it might be crucial for the incorporation of iron-sulfur clusters, redox centers that play a pivotal role in electron transfer processes.Mutations in the NDUFAF5 gene have been associated with mitochondrial diseases and Complex I deficiency, highlighting the significance of this protein in cellular energy metabolism. Such deficiencies can lead to a range of manifestations, including muscle weakness, neurodegeneration, and cardiomyopathy, reflecting the fundamental role of Complex I in ATP production in various tissues.
