Rhodopsins are ubiquitous light-driven membrane proteins that have diverse functions in nature, and value as optogenetics tools. Here the authors characterise type 1 viral channelrhodopsins, showing that they regulate intracellular calcium and can be used for the photocontrol of muscle contraction in vivo.
