3.8 Activation of transcription factors

We have already come across several examples of signalling pathways leading to activation (or inactivation) of transcription factors, which in turn modulate transcription of sets of genes leading to, for example, programs of differentiation or proliferation. You will also meet several other specific examples in subsequent chapters. For now, we shall examine one particular scenario, namely the activation of immediate early genes by MAP kinases, which illustrates some of the principles and deta

3.4.2 Cyclic AMP

The concentration of cyclic AMP (cAMP) in the cytosol increases 20-fold within seconds of an appropriate stimulus. This is achieved by the action of the plasma membrane-embedded protein adenylyl cyclase, which synthesizes cAMP from ATP (Figure 34). cAMP is short-lived, as with all second messengers, because it is continuously degraded by <
