• Circadian regulation of dynamin-related protein 1 (DRP1), a key mitochondrial fission protein, results in daily cycles of fission and fusion which are essential for circadian oscillations in ATP production
• Genetic and pharmacological abrogation of DRP1 activity abolished circadian network dynamics and eliminated circadian ATP production
