Biology: The Dynamic Science, Chapter 7 amplification An increase in the magnitude of each step as a signal transduction pathway proceeds. cell signaling The system of communication between cells through signaling pathways. cross–talk Interaction by which cell signaling pathways communicate with one another to integrate their responses to cellular signals. cyclic AMP (cAMP) In particular signal transduction pathways, a second messenger that activates protein kinases, which elicit the cellular response by adding phosphate groups to specific target proteins. cAMP functions in one of two major G–protein–coupled receptor–response pathways. diacylglycerol (DAG) In particular signal transduction pathways, a second messenger that activates protein kinases, which elicit the cellular response by adding phosphate groups to specific target proteins. DAG is involved in one of two major G–protein–coupled receptor–response pathways. effector
