The mitochondrial calcium uniporter, which mediates mitochondrial Ca2+ uptake, regulates key cellular functions, including intracellular Ca2+ signaling, cell-fate determination, and mitochondrial bioenergetics. Here, we describe two complementary strategies to quantify the uniporter’s transport activity. First, we detail a mitochondrial Ca2+ radionuclide uptake assay in cultured cell lines. Second, we describe electrophysiological recordings of the uniporter expressed in Xenopus oocytes. These approaches enable a detailed kinetic analysis of the uniporter to link its molecular properties to physiological functions. For complete details on the use and execution of this protocol, please refer to and.
