    Previous UsesCa2+ flux across the inner mitochondrial membrane regulates cell bioenergetics, cytoplasmic Ca2+ signals and activation of cell death pathways. Ca2+ uptake from the cytoplasm is driven by the electrochemical gradient generated during ATP production, mediated by a Ca2+ ion channel called the mitochondrial Ca2+ uniporter. Molecular components of the uniporter include MCU, the Ca2+ conducting pore, and MICU1, a MCU regulator that limits Ca2+ permeation through MCU at rest. MCUR1 is as an essential third component of the uniporter complex. In the absence of MCUR1, mitochondrial Ca2+ uptake is markedly reduced, with adverse cellular consequences, including compromised cellular bioenergetics, diminished oxidative phosphorylation and activation of autophagy.
