FSP1 (Ferroptosis Suppressor Protein 1), formerly known as AIFM2 (Apoptosis-Inducing Factor Mitochondrial 2), is a NADH-dependent coenzyme Q reductase that suppresses ferroptosis independently of the GPX4 pathway. FSP1 catalyzes the reduction of coenzyme Q10 (CoQ) to ubiquinol, which acts as a lipophilic antioxidant preventing lipid peroxidation in membranes.
FSP1 functions as an NADH-dependent CoQ reductase:
FSP1 prevents ferroptosis through CoQ reduction:
FSP1 is widely expressed:
