cyclin C and mitochondria

 ROS-induced degradation of Med13 by SCF^Grr1 mediates mitochondrial fragmentation and cell death.

cyclin c --> mitochondria fission

ROS stress --> MAPK

No stress: cyclin C in nuclear
Stress translocate cyclin C to cytosal.

So, cyclinC may influence yeast lifespan through its influence on mitochondria?
