== Function ==
[https://www.uniprot.org/uniprot/MICU1_HUMAN MICU1_HUMAN] Key regulator of mitochondrial calcium uniporter (MCU) required to limit calcium uptake by MCU when cytoplasmic calcium is low. Acts as a gatekeeper that senses calcium level via its EF-hand domains and sets a threshold for mitochondrial calcium uptake by MCU, thereby preventing mitochondrial calcium overload. Regulates glucose-dependent insulin secretion in pancreatic beta-cells by regulating mitochondrial calcium uptake. Induces T-helper 1-mediated autoreactivity, which is accompanied by the release of IFNG.<ref>PMID:16002733</ref> <ref>PMID:20693986</ref> <ref>PMID:23101630</ref> <ref>PMID:22904319</ref>
