Activating an invertebrate bistable opsin with the all-trans 6.11 retinal analogue

M. J. Rodrigues, O. Tejero, J. Muhle, F. K. Pamula, I. Das, C.-J. Tsai, A. Terakita, M. Sheves, G. F. X. Schertler

This study shows that the all-trans 6.11 retinal analogue activates the invertebrate bistable opsin JSR1 and enables complex formation with downstream signaling partners.
