Recombinant human CABC1 protein, also known as COQ8A or ADCK3. is a key player in cellular energy production and mitochondrial function. As a member of the ancient ubiquitous kinase-like (ABC1) family, it functions as a regulatory kinase in the biosynthesis pathway of coenzyme Q10 (CoQ10), an essential lipid-soluble electron carrier in the mitochondrial electron transport chain. The native CABC1 protein is anchored to the mitochondrial inner membrane and interacts with multiple CoQ biosynthesis enzymes, facilitating the stabilization and organization of the CoQ synthome complex.
The recombinant form is produced through heterologous expression systems like E. coli or mammalian cell cultures, enabling controlled study of its structure-function relationships. Structural studies reveal conserved ATPase and kinase-like domains critical for maintaining CoQ biosynthesis under metabolic stress. Mutations in the CABC1 gene are associated with cerebellar ataxia and CoQ deficiency disorders, making recombinant CABC1 invaluable for disease modeling, drug screening, and understanding mitochondrial respiration mechanisms.
Current research focuses on its dual role as both a metabolic sensor and a chaperone protein, particularly its interaction with lipid intermediates in energy-depleted conditions. Therapeutically, recombinant CABC1 serves as a potential target for treating mitochondrial encephalopathies and age-related degenerative diseases linked to CoQ dysfunction. (Word count: 198)
