Predicted to contribute to proton-transporting ATP synthase activity, rotational mechanism. Predicted to be involved in proton motive force-driven mitochondrial ATP synthesis. Predicted to act upstream of or within ATP biosynthetic process and proton transmembrane transport. Predicted to be located in mitochondrial inner membrane. Predicted to be part of proton-transporting ATP synthase complex. Orthologous to human ATP5MF (ATP synthase membrane subunit f).
