Light-Sensitive Intracellular Biomolecules

Light-sensitive intracellular biomolecules are specialized proteins that respond to specific wavelengths of light, playing roles in vision, circadian rhythms, photosynthesis, and cellular signaling. They are increasingly used as optogenetic tools to control cellular functions. These biomolecules often require a chromophore to absorb light, which then undergoes a conformational change that alters the protein's function and initiates downstream signaling pathways. Researchers engineer these proteins for applications like controlling neuronal activity and regulating gene expression with light.
