Scientists have moved another step closer to solving a decades-long mystery of how the flow of calcium into the cell's power source, the mitochondria, is controlled. By shutting down 50 genes, one at a time, they have identified a protein, MCUR1, that is part of an elaborate channel pore system and acts as an accelerator to help regulate calcium coming into the mitochondria.
