**Recombinant human COX18 protein** is a genetically engineered form of the cytochrome c oxidase assembly factor COX18. which plays a critical role in mitochondrial function. COX18. also known as COX20 in some organisms, is a conserved transmembrane protein localized to the mitochondrial inner membrane. It facilitates the assembly of cytochrome c oxidase (Complex IV), a key enzyme in the electron transport chain responsible for oxygen reduction and ATP synthesis. Specifically, COX18 interacts with the Cox2 subunit, aiding its membrane insertion and maturation during the biogenesis of Complex IV.
Dysregulation of COX18 has been linked to mitochondrial disorders and metabolic diseases, underscoring its physiological importance. Recombinant COX18 is typically produced using expression systems like *E. coli* or mammalian cell cultures, enabling high-purity yields for functional studies. Its recombinant form allows researchers to investigate mechanisms of mitochondrial respiratory chain assembly, screen for therapeutic targets, or model diseases associated with COX18 mutations. Applications extend to studying pathologies such as neurodegenerative diseases, cancer, and rare genetic syndromes tied to oxidative phosphorylation defects. Advances in structural biology and proteomics using recombinant COX18 have also shed light on its interaction networks, enhancing our understanding of mitochondrial dynamics and bioenergetics.
