Abstract
Inactivation of the Ca2+ extrusion mode of the retinal rod Na-Ca + K e xchanger is suggested to be the mechanism that prevents lowering of cy tosolic free Ca2+ to < 1 n M when rod cells are saturated for a prolon ged time under bright light conditions. Under these conditions, Ca2+ f luxes across disk membranes can contribute significantly to Ca2+ homeo stasis in rods.
