From Metabolic Flux to Protein Degradation: How Metabolic Enzymes and Protein Degradation Systems Jointly Regulate Cell Fate

Cell fate is determined not only by signaling cascades composed of receptors, kinases, and transcription factors, but also by two more fundamental regulatory processes. Metabolic enzymes control the direction and rate of nutrient conversion, thereby determining the energy, biosynthetic ...
