The resting membrane potential (Δψ) of the cell is negative on the cytosolic side and determined primarily by the plasma membrane's selective permeability to K<sup>+</sup> We show that lysosomal Δψ is set by lysosomal membrane permeabilities to Na<sup>+</sup> and H<sup>+</sup>, but not K<sup>+</sup>, and is positive on the cytosolic side. An increase in juxta-lysosomal Ca<sup>2+</sup> rapidly reversed lysosomal Δψ by activating a large voltage-dependent and K<sup>+</sup>-selective conductance (L ...[more]
