What Are The Basics Of Intracellular Signaling?

What Are The Basics Of Intracellular Signaling? The targets of such signaling pathways frequently include transcription factors that function to regulate gene expression. Intracellular signaling pathways thus connect the cell surface to the nucleus, leading to changes in gene expression in response to extracellular stimuli. What are the 4 steps in extracellular signaling? Communication by
