Function

function

Contributes to K+/H+ antiport activity by supporting proton efflux to control proton extrusion and homeostasis in chloroplasts in a light-dependent manner to modulate photosynthesis. Prevents excessive induction of non-photochemical quenching (NPQ) under continuous-light conditions. Indirectly promotes efficient inorganic carbon uptake into chloroplasts.
