- 요약The highly conserved ERK cascade controls organism development and homeostasis and is genetically deregulated in birth defects, neurocognitive disorders, and cancers. While the list of the ERK functions is vast and steadily growing, the full spectrum of processes controlled by any specific ERK activation event remains unknown. Here we show how new ERK functions can be systematically identified using targeted perturbations and global readouts of ERK activation. Our experimental model is the early Drosophila embryo, where ERK signaling at the embryonic poles has thus far only been associated with transcriptional patterning of the terminal structures of the future larva. Through a combination of imaging and phosphoproteomic analyses of the effects of acute optogenetic perturbations, we demonstrate that ERK activation at the poles is also critical for maintaining the speed and synchrony of embryonic cleavages throughout the embryo. Furthermore, through whole-genome sequencing of ribosome-protected footprints, we set the stage for understanding how ERK signaling affects mRNA translation at this embryonic stage. The presented approaches to interrogating phosphorylation networks, based on global analysis of short-term effects of acute optogenetic stimuli, reveals new functions of an extensively studied signaling event, and sets the stage for comprehensive understanding of signaling systems.
