Green fluorescent protein (GFP)-based calcium probes have been developed, but their limited signal intensity has made it difficult to measure calcium concentrations with good spatial and temporal ...
Schematic drawing of Cal-Light system. M13 and calmodulin proteins are fused to c-terminus and n-terminus of TEV protease (TEV-C and TEV-N), respectively. When Ca2+ arises in the cytosol, M13 and ...
