Biol. Chem. 294:1128-1141(2019). CC -!- FUNCTION: Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or CC Complex V) produces ATP from ADP in the presence of a proton gradient CC across the membrane which is generated by electron transport complexes CC of the respiratory chain. F-type ATPases consist of two structural CC domains, F(1) - containing the extramembraneous catalytic core and F(0) CC - containing the membrane proton channel, linked together by a central CC stalk and a peripheral stalk. During catalysis, ATP synthesis in the CC catalytic domain of F(1) is coupled via a rotary mechanism of the CC central stalk subunits to proton translocation. Part of the complex CC F(0) domain. A homomeric c-ring of probably 10 subunits is part of the CC complex rotary element. CC -!- SUBUNIT: F-type ATPases have 2 components, CF(1) - the catalytic core CC - and CF(0) - the membrane proton channel. CF(1) has five subunits: CC alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) has three main CC subunits: a, b and c. Interacts with TMEM70 and TMEM242 (By CC similarity). {ECO:0000250|UniProtKB:P48201}. CC -!- SUBCELLULAR LOCATION: Mitochondrion membrane {ECO:0000250}; Multi-pass CC membrane protein {ECO:0000250}. CC -!- PTM: Trimethylated by ATPSCKMT at Lys-110. Methylation is required for CC proper incorporation of the C subunit into the ATP synthase complex and CC mitochondrial respiration. {ECO:0000269|PubMed:30530489}. CC -!- DISEASE: Note=This protein is the major protein stored in the storage CC bodies of animals or humans affected with ceroid lipofuscinosis (Batten CC disease). CC -!- MISCELLANEOUS: There are three genes which encode the mitochondrial ATP CC synthase proteolipid and they specify precursors with different import CC sequences but identical mature proteins. {ECO:0000305}. CC -!- SIMILARITY: Belongs to the ATPase C chain family. {ECO:0000305}.
