GeneCards Summary for MICU2 Gene
MICU2 (Mitochondrial Calcium Uptake 2) is a Protein Coding gene. Gene Ontology (GO) annotations related to this gene include calcium ion binding and protein heterodimerization activity. An important paralog of this gene is MICU3.
UniProtKB/Swiss-Prot for MICU2 Gene
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).
