Dear Editor,Mitochondrial Ca2+homeostasis regulates energy production,cell division,and cell death.The basic properties of mitochondrial Ca2+uptake have been firmly established.The Ca2+influx is mediated by MCU,driven by membrane potential and using a uniporter mechanism(Vasington and Murphy,1962).Patch-clamp analysis of MCU currents demonstrated that MCU is a channel with exceptionally high Ca2+selectivity(Kirichok et al.,2004).
