AIFM1 (apoptosis inducing factor mitochondria associated 1) possesses redox activity, which helps in oxidative phosphorylation. In the mitochondria, AIFM1 helps in assembling or maintaining the mitochondrial respiratory complexes I and III. It plays a vital role in apoptosis. This gene is associated with COXPD6 (combined oxidative phosphorylation deficiency, encephalomyopathy, Cowchock syndrome and X-linked deafness with neuropathy.
