MICU2 controls mitochondrial calcium signaling and migration in neurons during development
Berezhnaya et al. showed that MICU2 is present in the brain during development but is replaced during maturation by MICU3. MICU2 loss during development results in neuronal overmigration in the cortex...

Dependence of mitochondrial calcium signalling and dynamics on the disaggregase, CLPB - Nature Communications
CLPB is a protein disaggregase that has been linked to human disease. Here, the authors show that in different models of chronic or acute loss of the mitochondrial disaggregase, mitochondrial Ca2+ han...
