Basal autophagy is as a compressive catabolic mechanism engaged in the breakdown of damaged macromolecules and organelles leading to the recycling of elementary nutrients. Thought essential to cellular refreshing, little is known about the origin of a constitutional rate of basal autophagy. Here, we found that loss of Drosophila vacuolar...

Eukaryotic initiation factor 4E (eIF4E) controls a crucial step of translation initiation and is critical for cell growth . Biochemical studies have shown that it undergoes a regulated phosphorylation by the MAP-kinase signal-integrating kinases Mnk1 and Mnk2 . Although the role of eIF4E phosphorylation in mammalian cells has remained elusive ,...

In metazoans, factors of the insulin family control growth, metabolism, longevity, and fertility in response to environmental cues. In Drosophila, a family of seven insulin-like peptides, called Dilps, activate a common insulin receptor. Some Dilp peptides carry both metabolic and growth functions, raising the possibility that various binding...
