SDHC (Succinate Dehydrogenase Complex Subunit C) is a key component of mitochondrial complex II (succinate-ubiquinone oxidoreductase), which plays a dual role in the tricarboxylic acid (TCA) cycle and the electron transport chain (ETC). As part of the succinate dehydrogenase (SDH) complex, SDHC anchors the catalytic SDHA and SDHB subunits to the inner mitochondrial membrane, facilitating the oxidation of succinate to fumarate and transferring electrons to ubiquinone. This process is critical for ATP production and cellular energy homeostasis.
Mutations in the SDHC gene are linked to hereditary paraganglioma-pheochromocytoma syndromes and other mitochondrial disorders, driving interest in studying its structure-function relationships. Recombinant SDHC protein is produced using expression systems like *E. coli* or mammalian cells, enabling researchers to investigate its role in disease mechanisms, enzyme kinetics, and interactions with other complex II subunits. Its production often involves tagging (e.g., His-tag) for purification and detection.
Studies using recombinant SDHC have advanced understanding of how SDH dysfunction contributes to tumorigenesis, particularly via pseudohypoxia pathways, and have supported drug discovery efforts targeting metabolic diseases or cancers. However, challenges remain in maintaining the protein’s native conformation and membrane-associated properties *in vitro*. Ongoing research focuses on optimizing expression protocols and reconstituting functional SDH complexes to model mitochondrial pathologies or screen therapeutic compounds.
