The Drosophila epidermal growth factor receptor (EGFR) is active in different tissues and is involved in diverse processes such as patterning of the embryonic ectoderm, growth and differentiation of imaginal discs and cell survival. During oogenesis, . . .

The ancient origin of sleep is evidenced by deeply conserved signaling pathways regulating sleep-like behavior, such as signaling through the Epidermal growth factor receptor (EGFR). In Caenorhabditis elegans, a sleep-like state can be induced at any . . .
