MICU1 and MICU2, two peas in a pod or entirely different fruits?
Fluctuations in mitochondrial matrix Ca2+ plays a critical role in matching energy production to cellular demand through direct effects on oxidative phosphorylation and ATP production. Disruption in mitochondrial Ca2+ homeostasis, particularly under pathological conditions such as ischemia or heart failure, can lead to mitochondrial dysfunction, energy deficit, and eventually death of cardiomyocytes. The primary channel regulating acute mitochondrial Ca2+ influx is the mitochondrial Ca2+ uniporter (mtCU), which is regulated by the mitochondrial Ca2+ uptake (MICU) proteins that were examined here.
期刊介绍:
Cell Calcium covers the field of calcium metabolism and signalling in living systems, from aspects including inorganic chemistry, physiology, molecular biology and pathology. Topic themes include:
Roles of calcium in regulating cellular events such as apoptosis, necrosis and organelle remodelling
Influence of calcium regulation in affecting health and disease outcomes
