Abstract:
Genetically-encoded calcium actuators (GECAs) stemmed from STIM1 have enabled optical activation of endogenous ORAI1 channels in both excitable and non-excitable tissues. These GECAs offer new non-invasive means to probe the structure-function relations of calcium channels and wirelessly control the behavior of awake mice.
