PLC hydrolyses phosphatidylinositol 4,5-bisphosphate (PIP2) into the second messengers inositol-1,4,5,-triphosphate (IP3) and diacylglycerol (DAG). The second messengers, including cGMP, activate channels that result in transmission of the light signal through the synapses. Typical examples are rhabdomeric photoreceptors in the eyes of protostomes.
