Funkcija
urediMitohondrijska ATP-sintaza katalizira sintezu ATP-a, koristeći elektrohemijski gradijent protona preko unutrašnje membrane tokom oksidativne fosforilacije. Sastoji se od dva povezana kompleksa sa više podjedinica: rastvorljivo katalitsko jezgro, F1 i komponenta koja se proteže kroz membranu , FO, koji sadrže protonski kanal. Kompleks F1 sastoji se od pet različitih podjedinica (alfa, beta, gama, delta i epsilon), sastavljenih u omjeru od 3 alfa, 3 beta i po jednog predstavnika ostala trz. F O ima devet podjedinica (a, b, c, d, e, f, g, F6 i 8). Ovaj gen kodira F6 podjedinicu kompleksa FO, neophodnu za nterakcijeF1 i FO. Za ovaj gen identificirane su alternativno prerađene varijante transkripta koje kodiraju različite izoforme.[7]
Podjedinica F6 je dio periferne drške koja povezuje komplekse F1 i FO i koja djeluje kao stator, kako bi spriječila određene podjedinice da rotiraju sa centralnim rotirajućim element. Periferna drškaka razlikuje se u sastavu podjedinica između mitohondijskih, hloroplastnih i bakterijskih F-ATPaza. U mitohondrijAma, periferna drškaka sastoji se od po jedne kopije podjedinica OSCP (oligomicin senzitivni vezni protein), F6, b i d.[8] U bakterijskoj ili hloroplastnoj F-ATPazi, ne postoji homolog[ podjedinice F6, čije se periferne drške sastoje od jedne kopije podjedinice delta (homologne OSCP) i dvije kopije podjedinice b u bakterijama, ili jedne kopije svake od podjedinica b i b' u hloroplastima i fotosintetskim bakterijama.
