| + | [https://www.uniprot.org/uniprot/MICU2_HUMAN MICU2_HUMAN] Key regulator of mitochondrial calcium uniporter (MCU) required to limit calcium uptake by MCU when cytoplasmic calcium is low (PubMed:24503055, PubMed:24560927, PubMed:26903221). MICU1 and MICU2 form a disulfide-linked heterodimer that stimulate and inhibit MCU activity, depending on the concentration of calcium (PubMed:24560927). MICU2 acts as a gatekeeper of MCU that senses calcium level via its EF-hand domains: prevents channel opening at resting calcium, avoiding energy dissipation and cell-death triggering (PubMed:24560927).<ref>PMID:24503055</ref> <ref>PMID:24560927</ref> <ref>PMID:26387864</ref> <ref>PMID:26903221</ref> | ||
