Abstract
The development of optogenetic control over signaling pathways has provided a unique opportunity to decode the role of signaling dynamics in cell fate programing. Here I present a protocol for decoding cell fates through systematic interrogation with optogenetics and visualization of signaling with live biosensors. Specifically, this is written for Erk control of cell fates using the optoSOS system in mammalian cells or Drosophila embryos, though it is intended to be adapted to apply generally for several optogenetic tools, pathways, and model systems. This guide focuses on calibrating these tools, tricks of their use, and using them to interrogate features which program cell fates.
