BcLOV4
Multi-Component SwitchBcLOV4 is a blue-light-responsive photoreceptor from Botrytis cinerea that functions as a single-component optogenetic module for rapid plasma membrane recruitment. Illumination drives cytosol-to-membrane translocation through direct protein-lipid electrostatic interaction, and fused cargo such as RhoA GTPase or RhoA-activating GEFs can be relocalized to the membrane with light.
