SDHA Flavoprotein (FP) subunit of succinate dehydrogenase (SDH) that is involved in complex II of the mitochondrial electron transport chain and is responsible for transferring electrons from succinate to ubiquinone (coenzyme Q). Can act as a tumor suppressor. Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily. 3 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
