Mitochondria are primarily appreciated for the generation of adenosine triphosphate (ATP), a chemical store of energy required by all cells. These organelles, however, also play key roles in apoptosis, autophagy and shaping cytosolic calcium (Ca2+) signaling via Ca2+ uptake into the mitochondrial matrix. This Ca2+ uptake is mediated chiefly via the mitochondrial Ca2+ uniporter (MCU), an inner mitochondrial membrane protein that oligomerizes to form a Ca2+ selective pore. MCU is regulated by several protein binding partners, including the recently identified MCU regulator-1 (MCUR1). MCUR1 stabilizes a higher order MCU heterocomplex through interactions with MCU …
