Summary
Optogenetics uses light and genetics to control cellular events. New tools based on Light, Oxygen, or Voltage (LOV) and Blue-Light-Utilizing flavin adenine dinucleotide (BLUF) domains offer advanced applications in biology and biotechnology.
Area of Science:
- Biotechnology
- Cell Biology
- Neuroscience
Background:
- Optogenetics enables non-invasive control of cellular events using light and genetics.
- Its applications extend beyond neuroscience to diverse biological systems.
- The development of novel light-sensitive proteins is rapidly expanding the optogenetic toolkit.
Purpose of the Study:
- To review the photochemical properties of LOV and BLUF photosensors.
- To highlight recent advances in using these flavoproteins for biological regulation and imaging.
- To discuss their application in synthetic photoswitches and fluorescent reporters.
Main Methods:
- Review of photochemical properties of LOV and BLUF domains.
- Analysis of recent advancements in their application.
- Summary of their use in designing synthetic photoswitches and reporters.
Main Results:

Channel Rhodopsins
Most organisms use photoreceptors to sense and respond to light. Examples of photoreceptors include bacteriorhodopsins and bacteriophytochromes in some bacteria, phytochromes in plants, and rhodopsins in the photoreceptor cells of the vertebral retina. The light-sensitive property of these receptors is because of the bound chromophores, such as bilin in the phytochromes and retinal in the rhodopsins.
Rhodopsins belong to the family of cell surface proteins called G-protein coupled receptors,...

Protein Dynamics in Living Cells
Different fluorescence-based techniques are used to study the protein dynamics in living cells. These techniques include FRAP, FRET, and PET.
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
