ATP synthase inhibitory factor 1 (ATPIF1) is a key regulator of the ATP synthase complex, which is responsible for producing ATP.[8] ATPIF1 has been implicated in various biomedical processes, for instance visual impairment, ischemia‐reperfusion injury, apoptosis, and carcinoma.[9] However, the role of ATPIF1 in PNR and Wallerian degeneration remains elusive. The gene discussed is ATP5IF1; the disease is carcinoma.
