Key regulator of mitochondrial calcium uptake required for calcium entry into mitochondrion. May act as a calcium sensor via its EF-hand domains, gating the activity of a calcium channel partner. Induces T-helper 1-mediated autoreactivity, which is accompanied by the release of IFNG. Belongs to the MICU1 family. 5 isoforms of the human protein are produced by alternative splicing.
