The protein kinase activated in the cAMP signal transduction pathway subsequently activates other proteins or enzymes in the cell, leading to a cellular response. This is a part of the amplification step in the signaling pathway where the signal is relayed and amplified to produce a significant cellular response.

In the CAMP Signal Transduction Pathway, a Protein Kinase Is
