title: Regulation of translation via TOR signaling: insights from Drosophila melanogaster.
abstract: The target of rapamycin (TOR) proteins are large protein kinases evolutionarily conserved from yeast to human. A large body of evidence demonstrates that TOR proteins function in a nutrient-sensing checkpoint whose role is to restrict growth under conditions of low nutrient availability. Under such conditions, TOR blocks the transmission of growth-promoting signals from extracellular stimuli. Recent data obtained by genetic studies in the fruit fly Drosophila melanogaster demonstrate the importance of both insulin-like signaling and TOR signaling in promoting growth. Importantly, these studies identified a major downstream target of TOR and insulin-like signaling as the translational machinery.
