It has come to our attention that Baughman et al. reported similar findings in parallel to those discussed in this Research Highlight, identifying the core component of the elusive mitochondrial calcium uniporter (MCU), which they termed MCU, through genomic, physiological, biochemical and pharmacological approaches. We apologize to the authors of this paper for the omission.
