Lamprey parapinopsin (UVLamP)
Multi-Component SwitchLamprey parapinopsin (UVLamP) is a Japanese lamprey (Lethenteron camtschaticum) parapinopsin used as a bistable, narrow-bandwidth optogenetic probe for control of the Gi/o pathway. It is activated by a millisecond UV light pulse and switched off by a millisecond blue light pulse, enabling reversible optical control of GPCR signaling.
