A variety of methods, devices and compositions are implemented for light- activated molecules. One such method is implemented for generating secondary messengers in a cell. A nucleotide sequence for expressing a chimeric light responsive membrane protein (e.g., rhodopsin) is modified with one or more heterologous receptor subunits {e.g., an adrenergic receptor (alpha1, Beta2)}. The light responsive membrane protein is expressed in a cell for producing a secondary messenger in response to light. |
