PE export from mitochondria to the ER during ER stress was further reduced in cells lacking
Mdm10p, a component of an ER-mitochondrial tethering complex that may facilitated lipid
exchange between these compartments. We also found that reducing mitochondrial PC
levels induces mitophagy. In conclusion, we show that ER stress affected PE export from
mitochondria to ER and the Mdm10p is important for this process.
