Function

Hormonal stimulation of cyclic adenosine monophosphate (cAMP) and the cAMP-dependent protein kinase PKA regulates cell growth by multiple mechanisms.

A hallmark of cAMP is its ability to stimulate cell growth in many cell types while inhibiting cell growth in others.

Features

 cell type-specific effects of cAMP on the mitogen-activated protein (MAPs) kinase (extracellular signal-regulated kinase, or ERK) cascade and cell proliferation
 activation of the GTPase Rap1
