Protein

Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial

Gene

SDHA

Organism
Bos taurus (Bovine)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

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 (By similarity).By similarity

Catalytic activityi

Succinate + a quinone = fumarate + a quinol.
