Beschreibung:
<jats:p>Cellular processes such as proliferation, differentiation, or migration depend on precise spatiotemporal coordination of protein activities. Correspondingly, reaching a quantitative understanding of cellular behavior requires experimental approaches that enable spatial and temporal modulation of protein activity. Recently, a variety of light‐sensitive protein domains have been engineered as optogenetic actuators to spatiotemporally control protein activity. In the present review, we discuss the principle of these optical control methods and examples of their applications in modulating signaling pathways. By controlling protein activity with spatiotemporal specificity, tunable dynamics, and quantitative control, light‐controllable proteins promise to accelerate our understanding of cellular and organismal biology. <jats:italic>WIREs Dev Biol</jats:italic> 2015, 4:545–554. doi: 10.1002/wdev.188</jats:p><jats:p>This article is categorized under:
