ATP synthase F(0) complex subunit C3 (ATP5G3) and similar proteins
ATP5G3 (also called ATP synthase lipid-binding protein, ATP synthase proteolipid P3, ATP synthase proton-transporting mitochondrial F(o) complex subunit C3, ATPase protein 9, or ATPase subunit c) transports protons across the inner mitochondrial membrane to the F1-ATPase protruding on the matrix side, resulting in the generation of ATP.
