SDHC also known as succinate dehydrogenase complex subunit C or succinate dehydrogenase cytochrome b560 subunit is an integral component of the mitochondrial complex II. It has a mass of approximately 15.3 kDa. SDHC is embedded in the inner mitochondrial membrane and is expressed in various tissues with a high mitochondrial content including skeletal muscle heart and brain. Mechanically SDHC anchors the succinate dehydrogenase (SDH) complex to the mitochondrial membrane facilitating effective electron transport during cellular respiration.

Biological function summary

The subunit SDHC plays a role in the conversion of succinate to fumarate in the tricarboxylic acid (TCA) cycle. By being part of the larger succinate dehydrogenase complex which also functions as part of the electron transport chain SDHC contributes to both energy production and metabolic regulation within cells. The SDH complex consists of four subunits: SDHA SDHB SDHC and SDHD. SDHC serving as an integral membrane protein ensures the proper anchoring and assembly of the complex which is essential for efficient electron transfer.

Pathways

SDHC is involved in both the TCA cycle and the mitochondrial electron transport chain. Within these pathways it enables the transfer of electrons from succinate to ubiquinone connecting two primary bioenergetic pathways. SDHC exhibits a relationship with other complex II subunits such as SDHA which catalyzes the oxidation reaction of succinate to fumarate. The electron flow through SDHC has an impact on the entire process of oxidative phosphorylation ultimately influencing ATP production in cells.

SDHC mutations and dysfunctions have links to conditions such as paragangliomas and pheochromocytomas. These tumors are associated with altered cellular metabolism and abnormal SDH complex activity. Mutations in the SDHC gene can lead to a disruption of normal electron transport chain function causing oxidative stress and contributing to tumorigenesis. Moreover SDHC mutations often co-occur with alterations in other SDH complex components such as SDHB further emphasizing the role of this complex in certain disease states.
