Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - containing the extramembraneous catalytic core, and F(0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation. Subunits alpha and beta form the catalytic core in F(1). Rotation of the central stalk against the surrounding subunits leads to hydrolysis of ATP in three separate catalytic sites on the beta subunits (Probable). Required during male mating behavior for the response to hermaphrodite contact, acting with lov-1 and pkd-2. May be involved in polycystin signaling. ATP + 4 H(+)(in) + H2O = ADP + 5 H(+)(out) + phosphate Subunit of the F-type ATPase which has 2 components, CF(1) - the catalytic core - and CF(0) - the membrane proton channel (Probable). Interacts (via N-terminus) with lov-1 (via PLAT domain). Peripheral membrane protein. Localizes to the cilium only in male-specific sensory neurons. Expressed in three categories of adult male sensory neurons: tail ray B neurons, HOB hook neuron and head cephalic (CEM) neurons. Widely expressed throughout development in both males and hermaphrodites. Belongs to the ATPase alpha/beta chains family.
