“…The Magnet system (pMag and nMag pair) derived from Vivid has the advantage of small size (151 aa), allowing rapid heterodimerization reversibility (half‐life is 6.8 s) . Additionally, a CAD‐Magnet system with increased avidity between pMag and nMag was developed and used to induce membrane ruffling . There are two reports that the Magnet system is superior to the CRY2/CIB1 system for application to gene expression systems.…”

“…Screening methods and random mutations could help enhance photoswitch performance, as demonstrated by the iLID, TULIP, and FKF1 systems. Additionally, it should be possible to enhance the avidity of photoswitches by using assembled domains, such as CAD and ferritin, as demonstrated by the development of the CAD‐Magnet system by the Sato group …”

Signal transductions are the basis for all cellular functions. Previous studies investigating signal transductions mainly relied on pharmacological inhibition, RNA interference, and constitutive active/dominant negative protein expression systems. However, such studies do not allow the modulation of protein activity with high spatial and temporal precision in cells, tissues, and organs in animals. Recently, non-channelrhodopsin-type optogenetic tools for regulating signal transduction have emerged. These photoswitches address several disadvantages of previous techniques, and allow us to control a variety of signal transductions such as cell membrane dynamics, calcium signaling, lipid signaling, and apoptosis. In this review we summarize recent advances in the development of such photoswitches and in how these optotools are applied to signaling processes.

Controlling Cells with Light and LOV

et al. 2018

Optogenetics is a powerful method for studying dynamic processes in living cells and has advanced cell biology research over the recent past. Key to the successful application of optogenetics is the careful design of the light‐sensing module, typically employing a natural or engineered photoreceptor that links the exogenous light input to the cellular process under investigation. Light–oxygen–voltage (LOV) domains, a highly diverse class of small blue light sensors, have proven to be particularly versatile for engineering optogenetic input modules. These can function via diverse modalities, including inducible allostery, protein recruitment, dimerization, or dissociation. This study reviews recent advances in the development of LOV domain‐based optogenetic tools and their application for studying and controlling selected cellular functions. Focusing on the widely employed LOV2 domain from Avena sativa phototropin‐1, this review highlights the broad spectrum of engineering opportunities that can be explored to achieve customized optogenetic regulation. Finally, major bottlenecks in the development of optogenetic methods are discussed and strategies to overcome these with recent synthetic biology approaches are pointed out.

Since the neurobiological inception of optogenetics, light-controlled molecular perturbations have been applied in many scientific disciplines to both manipulate and observe cellular function. Proteins exhibiting light-sensitive conformational changes provide researchers with avenues for spatiotemporal control over the cellular environment and serve as valuable alternatives to chemically inducible systems. Optogenetic approaches have been developed to target proteins to specific subcellular compartments, allowing for the manipulation of nuclear translocation and plasma membrane morphology. Additionally, these tools have been harnessed for molecular interrogation of organelle function, location, and dynamics. Optogenetic approaches offer novel ways to answer fundamental biological questions and to improve the efficiency of bioengineered cell factories by controlling the assembly of synthetic organelles. This review first provides a summary of available optogenetic systems with an emphasis on their organelle-specific utility. It then explores the strategies employed for organelle targeting and concludes by discussing our perspective on the future of optogenetics to control subcellular structure and organization.
