Optogenetics in Developmental Biology: using light to control

Common optogenetic reagents (Welberg, 2013) are currently optimized for extremely rapid and transient activation or suppression of action potential firing in individual cells. Moreover, while optogenetic reagents that stay active for minutes or longer are available (Berndt et al., 2009), their use for

This allows a targeted analysis of individual signalling hubs devoid of inter-connectivity with endogenous interacting components.

These were initial attempts at designing optogenetic 4EBP2 and eIF4E constructs, which encountered difficulties with in vitro characterization. Altogether, the constructs presented in this work expand the current optogenetic toolbox and will hopefully allow researchers to dissect the dynamic molecular events underlying translation.


optogenetic control of transgene expression has been illustrated by a successful modular exchange of the intracellular domain of the G-protein coupled receptor rhodopsin, which is responsible for downstream signal-ing.24,25 In doing so, these chimeric receptors, called optoXRs, could be triggered by light of a distinct wave-
