Ubiquinol-cytochrome c reductase complex assembly factor 1, often abbreviated as UQCC1, is an essential protein implicated in the mitochondrial respiratory chain, specifically within the context of complex III assembly. Complex III, also known as the cytochrome bc1 complex or ubiquinol-cytochrome c oxidoreductase, is a critical component of the mitochondrial electron transport chain that generates the electrochemical gradient used to produce ATP, the cell's energy currency.

UQCC1 is involved in the early stages of complex III assembly, where it plays a pivotal role in the stabilization of pre-complexes that precede the formation of the fully functional complex III. The exact mechanism through which UQCC1 facilitates the assembly is not fully elucidated, but it is known to interact with other assembly factors and core components of the complex, suggesting a direct role in the proper integration of these subunits into the nascent complex.Mutations or deficiencies in UQCC1 can lead to disorders related to mitochondrial function, as the proper assembly and function of complex III are paramount for oxidative phosphorylation. Manifestations of such deficiencies are typically multisystemic, reflecting the critical role of mitochondria in various tissues. These phenotypes underscore UQCC1's importance in maintaining the integrity of mitochondrial respiration.
